Title: Logical operation circuit
Inventor: KIMURA KAZUO
IPC: H03K19/086
Filed: 1983-05-17
Abstract: PURPOSE:To perform high-speed operation through simple circuit constitution by providing three pairs of transistors (TR) which perform switching operation, three two-phase signal sources, and a resistance for leading a signal out. CONSTITUTION:Two-phase output signals (a)-(f) of signal sources 1-3 are inputted to an OR operation circuit 40. When the highrer potential of each two- phase signal is 1 and the lower potential is 0, the output signal 1 of the OR operation circuit 40 is 1 and an output signal (k) is 0 when a TR27 is on and a TR26 is off, when the TR27 is off, a TR25 is on, and a TR24 is off, or when the TRs 27, 25, and 22 are off and the TR26, 24, and 23 are on. Consequently, the logical operation circuit is composed of a small number of TRs and the high- speed operation is performed.

Title: High frequency power superposing system
Inventor: UEDA TOSHIHIKO
IPC: H04B3/54
Filed: 1993-03-23
Abstract: PURPOSE:To obtain a high frequency power superposing system capable of transmission between a high frequency signal and AC power without influencing each other as a noise. CONSTITUTION:A low-pass filter 2 removes a high frequency noise from AC power and a high-pass filter 5 removes a low frequency noise from the high frequency signal from a signal transmission unit 7. A two-wire type power line 9 superposes AC power and the high frequency signal after removing noise from them and low-pass filters 3 and 4 provide only the AC power among the superposed signals for signal transmission units 7 and 8. The high-pass filter 5 provides only the high frequency signal among the super posed signals for the signal transmission unit 8.

Title: Intake system of engine
Inventor: ONODERA HIROKI
IPC: F02B25/16
Filed: 1980-06-28
Abstract: PURPOSE: To prevent the noise increase at the idling time by closing off the connecting passage between an intake passage at the down stream of a throttle valve of a carburetor and an empty chamber during the idling.  
     CONSTITUTION: A valve 17 is provided on the connecting pipe 16 between an intake passage 8' at the down stream of a throttle valve 13 of a carburetor 1.

Title: Speed control system of unattended cart
Inventor: YAMAUCHI KOUJI
IPC: G05D13/62
Filed: 1979-07-13
Abstract: PURPOSE: To obtain a stop precision and safety on operations with a simple constitution, by cutting off a part of the inductive band and by detecting this cut part to generate a speed reduction command.  
     CONSTITUTION: When unattended cart 18 goes from point A to point B (the cut position), where reflection bands 1A and 1B are not provided, while being driven in a high speed, the light radiated from lamp 6 is not reflected sufficiently onto detecting elements 4aW4j of reflection light detecting unit 3, and the detection signal is broken temporarily, and the speed reduction command is issued from running control circuit 8 to motor driving circuit 10 by the fall of the detection signal during passage through cut distance l 1  from point A to point B where said reflection bands are not provided. As a result, the speed of cart 18 is reduced, and cart 18 can be caused to run in a low speed in distance l 2  from point B to point C where stop point 17 is provided, and cart 18 can be stopped from the speed reduction state at stop point 17. Therefore, a high stop precision can be obtained.

Title: Controller of copying machine
Inventor: TACHIKA TETSUJI
IPC: G03G15/01
Filed: 1983-05-20
Abstract: PURPOSE:To perform plural copying operations different in mode without setting a copy mode every time one kind of copying operation is completed and to prevent data output at improper timing, by controlling the output of the 2nd data from a storage means on the basis of a key input signal after one copying operation based upon the 1st data is completed. CONSTITUTION:Several kinds of set data are transferred and stored in a storage circuit with an ENT switch K6 and then when a COPY switch K12 is pressed, the setting contents are read out of the storage circuit in the setting order to start copying operations. This switch is used to reastart the copying device which is stopped temporarily with a CHANGE switch K9 or PAUSE switch K10. When only one kind of copying operation is carried out without using the storage circuit, data are set with switches K1, K2, and K5, and then the COPY switch K12 is pressed; and a switch K13 is used for taking only one copy. Plural combinations of set data on the selection of necessary color, the selection of the necessary number of sheets, and the size of copying paper are stored in the storage circuit previously, and they are read out successively to carry out copying operations.

Abstract: PURPOSE:To simplify the cutting of heat-exchanging tube bundles and as well to prevent burring in a machining device for cutting tube bundles, etc., by replaceably attaching annular saw teeth to the front end of a pipe-like rotary member. CONSTITUTION:By hydraurically operating a piston rod 27 and a cylinder 22, the height of a machine and the position of annular saw teeth 1 at the front end of a pipe-like rotary member 6 are set at predetermined height and position. Then, a motor 16 is rotated to move the cylinder forward or backward. With this arrangement, the front end annular saw teeth 1 successively cuts tube bundles 25. At this time water is discharged to the cutting section from a valve 31. Similarly, a pipe wall is drilled in combination with a centering jig so that a branch pipe fitting hole may also be formed. With this arrangement the machining of a pipe may be simplified with no burring.

Title: Body detector
Inventor: HATSUTORI KATSUJI
IPC: G01V8/16
Filed: 1978-07-20
Abstract: PURPOSE: To prevent the effect of disturbance electromagnetic waves, by using a Fabry-Perot semiconductor laser and photo-fibers.  
     CONSTITUTION: A long photo-fiber 8 and a short photo-fiber 10 are each connected to end surfaces 6, 7 forming a resonator of a semiconductor laser 5 in non-reflecting shapes. An end surface 12 of a nose portion of the short photo-fiber 10 is obliquely cut in order to treat it so that reflection at the inside of the end of the fiber not take place. Thus, laser rays do not return to the semiconductor laser 5 when there is no body 13, and light reflected on the surface passes through the fiber 10 and returns to the laser 5 when there is the body 13. Consequently, light that is projected from the end surface 6 and connected to the fiber 8 changes, and photo-signals can be transmitted to long distances by means of the long fiber 8 without being subject to the influence of disturbance electromagnetic waves.

Title: Dry lithographic original printing plate of direct drawing type
Inventor: YANAGIDA SHUNICHI
IPC: B41C1/055
Filed: 1995-04-14
Abstract: PURPOSE: To improve sensitivity in a heat-sensitively broken, direct-type dry lithographic printing form plate by letting a heat-sensitively broken layer contain a pyrolytic compound dyed with dyestuffs. CONSTITUTION: A heat-sensitively broken layer is partially or totally decomposed by heat instantaneously. At this time, a dye is used as a compound to efficiently convert laser light to heat, preferably a dye that has the maximum absorption wavelength in the range of 400 1200nm is used. Specifically, various kinds of coloring matter such as cyanine series dyes for the electronics and recording purpose can be used. Although these kinds of dyes are effective by themselves to improve sensitivity, a combination of two or more kinds of dyes can improve sensitivity more. A pyrolytic compound such as nitrocellulose or the like is dyed with these dyes. Molecules of the dyes generate heat when absorbing infrared rays or near infrared rays, and the heat brings about a thermal decomposition in the adjacent pyrolytic compound efficiently.  Eventually, the sensitivity of a printing form plate is improved.
