Title: Gear form rolling tool
Inventor: TAKEDA SHIN
IPC: B21H5/02
Filed: 1985-09-20
Abstract: PURPOSE:To improve the dimension accuracy of a gear by providing a detaining plate on both end faces of a tooth part of a die, and also providing a chamber forming part on a boundary of the tooth surface of the tooth part and the detaining surface of the detaining plate. CONSTITUTION:Detaining plates 6, 7 are placed on both side faces of a die 1, and also, its inside surfaces are formed to the same tooth profiles 6a, 7a as a tooth profile of a rolling die. Subsequently, a chamfer forming part is formed by connecting the detaining surfaces 6b, 7b and the surfaces 6a, 7a by straight lines 6c, 7c whose inclination angle is 15-75 degrees, or a circular arc curve. When a blank is welded by pressure by plural dies 1 and rotated, a material of the blank flows into the detaining surfaces 6b, 7b and the chamfer forming parts 6c, 7c, too, and by the chamfered part of the detaining plate, a chamfered part is formed exactly on both ends of the tooth profile of the blank. According to this method, the dimension accuracy of a gear is improved.

Title: Air-fuel ratio control device of internal combustion engine
Inventor: IWASAKI YASUKO
IPC: F02D45/00
Filed: 1994-09-02
Abstract: PURPOSE: To reduce emissions by improving the responsiveness of an air-fuel ratio sensor when the engine is cold. CONSTITUTION: If an engine is judged to be in a cold state (S11, S12), cold engine states SLH2, SLL2 are selected in which two slice levels SLH, SLL are more closely spaced than in a hot engine state. Correspondingly, during cold engine operation the responsiveness of an oxygen sensor worsens and emissions also worsen, but since the time required to cross one of the slice levels and then cross the other, i.e., response time can be reduced, the responsiveness can be enhanced and thus the emissions reduced.

Title: Method of computing target image coordinates on monitor screen
Inventor: MURAKAMI NAOYUKI
IPC: A63F13/426
Filed: 1999-07-26
Abstract: PROBLEM TO BE SOLVED: To make computable target coordinates from the measuring time by measuring the length of the time from the generation of a vertical synchronous signal of a composite signal for displaying a target image on a video monitor until a video signal changes peculiarly. SOLUTION: A composite signal flows from a video camera by light emission of a target 1A, and a vertical synchronous signal is generated in every field. A video signal appears an analog signal of voltage magnitude, and when the analog signal is shown on a plane of one field, as it approaches the center of a target image 1, the higher the voltage becomes. When it exceeds the comparator level, it is recognized that the video signal changes peculiarly. The vertical synchronous signal resets a binary counter 18 and a flip-flop(FF) 14. When it becomes above the comparator level, a video signal input to a voltage comparator 13 is input to the FF 14 to be put in the set state, so that a circuit 17 is interrupted to end counting of a counter 18. The count time is inputted to Y-axis ROM memories 19, 20 to compute X-axis and Y-axis coordinates.

IPC: B65G1/04
Filed: 1999-07-26
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous detection of protrusion by swelling of packing and a label by arranging a protrusion detecting means for separately detecting whether it is protrusion of an article itself or protrusion of packing and outer packing such as a label in a carrying device for detecting protrusion of the article from a cargo bed of the carrying device. SOLUTION: A stacker crane 2 of an automatic warehouse lifts a transfer device 12 for transferring an article 6 together with a pallet 10 by a lifting table 14, and prevents protrusion of the article 6 by blowing wind against the article 6 from nozzles 16 of four air blowers installed on a cage 22 of this lifting table 14. In this case, the lifting table 14 is provided with a noncontact protrusion detecting sensor having a light emitting part 24 and a light receiving part 26. A signal processing part 30 checks whether or not a protrusion detecting signal from the light receiving part 26 continuously exists for a prescribed time or more to judge that it is protrusion of packing 8 when the duration of the protrusion detecting signal is less than the prescribed time and that it is protrusion of the article 6 itself when the duration is not less than the prescribed time.

Title: Manufacture of semiconductive fluororesin molding and its use method
Inventor: ONISHI KAZUAKI
IPC: B29C48/32
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of a large disorder of a local electric resistance by melt extrusion molding a thermoplastic fluororesin containing conductive carbon black by a screw extrusion molding machine so that a shearing ratio at the time of the melt extrusion molding becomes a specific value or less. SOLUTION: A thermoplastic fluororesin containing conductive carbon black is melt extrusion molded by a screw extrusion molding machine so that particularly a shearing ratio at the time of the melt extrusion molding becomes 130 or less or preferably a range of 60 to 125. Here, the reason why the ratio is specified at 130 or less is because first the ratio is a ratio of a shearing ratio stress to be loaded to melted mixed resin in an extrusion step in the screw extruder and in the case of applying to a suitable application the ratio depends upon whether a large disorder occurs at the electric resistance value or not. If the ratio is 130 or less and the resin is melt extrusion molded, no occurrence of the disorder and further the molding can be manufactured with a high surface accuracy.

Title: Electric pot
Inventor: KITAZAWA SATORU
IPC: A47J27/21
Filed: 1999-07-26
Abstract: PROBLEM TO BE SOLVED: To contain purifying materials in a water purifier as much as possible by effectively using a restricted space in a vessel. SOLUTION: A tubular water purifying passage 14 is formed in a water purifier 11. A hole for discharging water or hot water to a vessel 1 is not formed in any part of the water purifying passage 14. The water or the hot water uniformly comes into contact with purifying materials 15 when it passes through the water purifying passage 14 so that an efficient water purification is carried out when the water or hot water reaches a discharge port 13. Since the water purifying passage 14 is tubular, the water purifying passage 14 can be arranged so as to be laid on the upper part of the vessel 1. Accordingly, a resticted space in the vessel 1 can be effectively used so that much content volume of the water purifying passage 14 for containing the purifying materials 15 can be ensured.

Title: Noise canceling system
Inventor: NAMEKAWA MAKOTO
IPC: G10K11/178
Filed: 1992-08-07
Abstract: PURPOSE:To enhance an engine noise canceling effect by canceling a secondary harmonic component and other harmonic components in addition. CONSTITUTION:A noise cancel controller 36 constantly cancels a harmonic component (a secondary harmonic component) which is on the highest level among harmonic components which are included in an engine noise and which are derived from an engine speed, regardless of the engine speed. On the other hand, with regard to harmonic components other than the harmonic component which is on the highest level, the harmonic component to be canceled is either automatically indicated by a harmonic component indicating part 34, corresponding to the engine speed, or selectively indicated by a switch 35. A reference signal generating part 33 inputs a reference signal of the harmonic indicated into a noise cancel controller 37, so that the harmonic component is canceled by adaption signal processing.

Title: Synchronous system, synchronous subsidiary station and synchronizing method in wide area radio network
Inventor: NAKAJIMA NOBUO
IPC: H04B7/26
Filed: 1999-07-26
Abstract: PROBLEM TO BE SOLVED: To prevent synchronization from being collapsed and to enable accurate synchronization establishment. SOLUTION: This system consists of a synchronous reference station 21, primary subsidiary stations 22 (221 and 222) and secondary subsidiary stations 23 (231 to 236). A signal for synchronization is distributed in the steps of a synchronous reference station 21 → a primary subsidiary stations 22 → a secondary subsidiary stations 23 → a tertiary subsidiary stations, and the system has a hierarchical structure as a synchronous system. The oscillators of the stations 21 and 22 that are at upper positions in the hierarchical structure are composed of an atomic oscillator such as highly stable cesium atomic oscillator and rubidium atomic oscillator.  The synchronous reference station intermittently transmits a signal for synchronization to the primary subsidiary stations (one time a day or an hour), and the primary subsidiary stations frequency (almost continuously) transmit the signal for synchronization to the secondary subsidiary stations.

Title: Arrangement method for charge coupled device of scanner
Inventor: UU BIN-SHIU
IPC: H04N1/193
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To facilitate a control process of a CCD by setting an effective scan range according to a positioning mark that is identified from the image data arrangement of a test area formed by the CCD and an A/D converter. SOLUTION: A scan module 20 is moved to a position under a black slip by a step motor and scans a test area 32 to form an image data arrangement consisting of the images of the area 32 by means of a CCD 22 and an A/D converter. Then a positioning mark is identified from the image data arrangement, and an effective scan area is formed to decide the start and stop positions of the allowed image data and then stored in a memory. These processes are carried out when the power supply of a scanner is turned on to set an effective scan range of the CCD 22 or can be carried out before every scanning of a new document. Thus, a production process where the CCDs are accurately arranged can be omitted since the effective scan range of each CCD is automatically set.

Title: Supermagnetstriction alloy
Inventor: KOBAYASHI TADAHIKO
IPC: C22C28/00
Filed: 1989-08-18
Abstract: PURPOSE:To obtain the subject alloy showing high supermagnetstriction in a low magnetic field, having good temp. characteristics and furthermore having excellent mechanical characteristics by regulating a Laves type intermediate compound layer of Dy-Tb-Fe-Mn series having specified compsn. as the main phase. CONSTITUTION:The supermagnetstriction alloy is the one having the compsn. of, by atomic ratio, (TbxDy1-x) (Fe1-yMny)z and having a Laves type intermetallic compound AB2 phase as the main phase; where 0.35<=x<=0.9, 0.001<=y<=0.6 and 1.4<=z<=2.1 are regulated. In the alloy, when the ratio of rare earth metals to transition metals is >2.1z, a compound phase having the above ratio of 1:3 is formed to deteriorate the magnetstriction characteristics. Moreover, in the case of >1.95z, the volume ratio occupied by the compound AB2 is approximately 100% to deteriorate the toughness, so that <=1.95z is preferably regulated. Furthermore, in the case of <1.4z, the ratio occupied by the compound AB2 is less than 50% to deteriorate the magnetstriction characteristics. Extremely high magnetstriction constant can be obtd. by (x) in the above range and, as for (y), the quantity more than the lower limit is needed in the view of toughness and workability and, for the upper limit or more, there occurs a problem in the point of temp. stability.

Title: Portable radio communication equipment
Inventor: SAITO TAKESHI
IPC: H04W88/02
Filed: 1989-08-18
Abstract: PURPOSE:To realize an equipment having a receiver section adhered closely to everyone's ear without a sense of disorder offering excellent sense of wearing contact and click by devising the receiver section that a contact angle of the receiver section to the ear is revised desirably with no adjustment in response to the preference of a user or the like. CONSTITUTION:When external forces A-D are exerted to a receiver section 5, a thin section 5b as shown in figure is easily deflected in response to the external forces A-D thereby allowing an angle of a main body 5a of the receiver section 5 to be changed. Suppose that the external forces A-D are external forces exerted to the receiver section 6 when the user wears the receiver section 5 to the ear, then the main body 5a, that is, the part of the receiver section 5 in contact with the ear follows and is displaced in an optional direction according to the external forces A-D and the contact angle is changed. Thus, it is possible for the user to contact the receiver section 5 to the ear at a desired angle and the contact angle is varied with everyone's preference. Moreover, the receiver section 5 has a proper reaction by the deflection thereby improving the excellent contact of use with a proper contact reaction to the user, not a 'flabby' contact sense.
