IPC: C22C38/00
Filed: 1984-11-08
Abstract: PURPOSE:To produce easily sintered parts having excellent corrosion resistance and dimensional accuracy by using Ni-Fe alloy powder as a raw material for sintered parts in the stage of producing the ferrous sintered parts. CONSTITUTION:A lubricating material is mixed with the powder of the Ni-Fe alloy contg. 30-55% Ni and the mixture is put into a metallic mold by which the mixture is molded under the pressure and the molded parts having a desired shape are manufactured.

Abstract: PURPOSE:To make it possible to observe a fine sight not only at the time of reflected light but also at the time of transmitted light and to improve the quality of a display device by joining a character part to the back side of a mask part by adhesive. CONSTITUTION:As to the mask part 2 and the character part 3, an adhesive layer 4 is formed on the back side of the mask part 2 by means of silk printing, etc., and the character part 3 is joined to the back side of the mask part 2 so as to be completed as one display panel 1. Since the mask part 2 and the character part 3 are separately formed, a space part corresponding to the character part 3 shown by 2c is generated in the mask part 2 even after joining the mask part 2 and the character part 3, so that paint, etc., forming the character part 3 does not flow into the space part 2c, and there is no possibility that colors are mixed. Thus, the boundary line between the mask part 2 and the character part 3 can be made drastically clear when it is observed by the reflected light.

Abstract: PURPOSE:To make the film thickness of a gate electrode thick sufficiently even at side walls of an operating layer and effectively prevent occurrences of malfunctions due to disconnection of the gate electrode by forming an insulating film on the side walls of the operating layer which is traversed with the gate electrode. CONSTITUTION:An insulating film 10 consisting of SiN or SiO2 and the like is deposited by a plasma CVD process or sputtering in such a manner that its film is wound round an inverse mesa part. Upper parts of an n<+> type GaAs epitaxial layer 2 and an n-type GaAs epitaxial layer 1 are treated with wet etching by using the insulating film 10 on which a recessed part formation region is opened as a mask and then, a recessed part 3 is formed. Source and drain electrodes 5 and 6 are formed and finally, a gate electrode 11 is formed so that its electrode traverses the recessed part 3. As parts 10a and 10b of the insulating film 10 are deposited to side walls 8a and 8b of an operating layer having the inverse mesa part, a cut inwards on the above operating layer is relaxed. Consequently, the film thickness of the gate electrode is secured sufficiently even on its shoulder parts, that is, the side wall parts 8a and 8b of the operating layer.

Abstract: PURPOSE:To form copy forgery preventive paper suitable for a color copying machine by a method wherein when both of a design pattern having an ornamental effect and a background pattern composed of a tint which is clearly identified from the pattern are erased when they are processed with the copying machine. CONSTITUTION:A large size design pattern 2 provided at a surface central part of base paper 1 is constructed from 165 lines 10% dot composed to thick red. Then, a background pattern 3 other than the design pattern is constructed from 165 lines 10% dot composed of blue green in complementary color relation to red. Further a note 4 with statement 'this paper contains a red design and a blue green pattern.' is printed on a surface lower part of the base paper 1. When this paper is processed with a latest color copying machine, the 165 lines 10% dot is not reproduced with the copying machine irrespective of a shade of coloring, and neither the design pattern nor the background pattern appear on copying paper 5. Therefore, a appearance as if they had disappeared is presented and besides, only the note 4 is reproduced. Then, said copy can be easily recognized not to be a true document.

Title: Recording or reproducing device
Inventor: KATSUKI SHINJI
IPC: G11B7/09
Filed: 1994-09-05
Abstract: PURPOSE: To shorten the adjusting time by executing automatic adjustments and storing adjusting values in a memory at the time of shipment from the factory, reading out then at the time of starting up the device and transferring them to their respective adjusting parts to be settled. CONSTITUTION: At the time of shipment from the factory, all adjustments are performed, and each adjusting value for each individual adjusting item is stored in an EEP-ROM 21. When a power source of the device is turned on by the user, a control value is read out of the ROM 21 by a system controller 11. Then, this adjusting value is supplied to a servo circuit 9 and an RF amplifier 7, etc., and after setting the individual setting items to their adjusting values, the reproducing operation is allowed to take place. By this method, the start-up operation can quickly be finished. After starting the reproducing operation, an error rate is monitored by the controller 11, and when the rate is deteriorated from a prescribed value, the automatic adjustment is executed during a nonreading period. Consequently, the start-up time for the recording/reproducing operation can thus be shortened.

Abstract: PURPOSE:To simplify a circuit and to make a fast response by varying the frequency of a clock signal for time measurement so that variation in the sound speed of an ultrasonic wave with temperature is compensated. CONSTITUTION:The sound wave has a temperature characteristic of upsilon=331.45+0.607tm/sec. For example, the ambient temperature is 20 deg.C and the real distance from an ultrasonic oscillator to a body to be measured is 1m. At this time, the time T (distance measurement section) from the transmission of the ultrasonic wave from the ultrasonic oscillator to the reception of its reflected wave by the same oscillator is measured by an arithmetic circuit 14 on the basis of the counted value of a clock of 1MHz (1mus) counted by a counter 11, so that the counted value (n) is 5820. Then, when the ambient temper ature is 0 deg.C, the counted value of the clock is 6034 and an error in measurement of 3.7% occurs at 0 deg.C. Namely, a clock frequency only has a temperature characteristics of -0.18%/ deg.C and a clock oscillation circuit 14 is controlled by a temperature sensing element 13 for the purpose.

Title: Friction clutch
Inventor: OIKE TATSUYA
IPC: F16D25/06
Filed: 1986-10-02
Abstract: PURPOSE:To enable the whole clutch to be miniaturized, by pushing or separating input side friction plates toward or from output side friction plates by means of the discharge pressure from a hydraulic pump, so that a large spring load is not added to a piston at any time. CONSTITUTION:A part of operating oil discharged from a discharge communicating hole 227 by the displacement of a spool is introduced into a piston push-back chamber 407 side. Consequently, a pressure plate 408 and an input side friction plates 417 are separated from an output side friction plates 416, and the torque of an input side shaft 102 is not transmitted to an output side shaft 530. If the spool displaces more than a prescribed value, the discharge side pressure of a pump is introduced into a piston push-out chamber 406, and inversely the suction side pressure is introduced into the piston push-back chamber 407. Consequently, a piston 414 displaces to the pressure plate 408 side. Receiving this displacement, the pressure plate 408 and input side friction plates 417 displace so as to come into contact with the output side friction plates 416. Accordingly, it is not necessary to burden the friction plates always with a large spring load, and the whole clutch can be miniaturized.
