Title: Manufacture using constraining jig
Inventor: ASAI TAKANAGA
IPC: B23K3/00
Filed: 1989-03-24
Abstract: PURPOSE:To prevent the member from being deformed by placing a spacer between the member and a constraining jig at the time of brazing plural members by using the constraining jig, and absorbing a difference of coefficients of thermal expansion of the constraining jig and the member at the time of brazing. CONSTITUTION:A holding plate 22 and 23 are placed in the upper part and the lower part of a member 14, a metallic spacer 18 made of a material which is half melted or melted at a melting temperature of a brazing filler metal is interposed between the member 14 and a constraining jig 16, and the member 14 is tightened with a nut 24 and a bolt 16 of the constraining jig 16. When the member 14 is heated in a state that it remains tightened by the constraining jig 16, the member 14 is brought to thermal expansion but since the spacer 18 is half melted or melted, the tightening pressure is not varied so much. In such a way, deformation and damage of the member can be prevented.

Title: Disturbing wave eliminating circuit
Inventor: HARA YASUHIKO
IPC: H01Q21/29
Filed: 1987-03-27
Abstract: PURPOSE:To facilitate the selection of a modulator in a loop circuit while making the response of the loop circuit constant regardless of an input level by amplifying an auxiliary signal of a side lobe canceller to a prescribed value decided by a limiter amplifier. CONSTITUTION:An auxiliary channel is provided with a directional coupler 23 to detect an auxiliary channel signal level, a level detection circuit 24, a switch 25 disconnecting the side lobe canceller circuit eliminating a disturbing radio wave from a detected signal from a main channel, and a limiter amplifier 22 amplifying the auxiliary channel signal to a prescribed level additionally. Through the constitution above, in amplifying a signal inputted to the auxiliary channel to be a prescribed value by using the amplifier 22, a half gain of the canceller is expressed as G¦h¦<2>, where (h) is an amplified output value, resulting that the response of a loop circuit is made constant independently of the input level. Moreover, the circuit 24 disconnects the canceller from the main channel when the detected level is lower than the setting value, allowing the switch 25 to eliminate the effect of noise.

Title: Controlling device for electric motor vehicle
Inventor: AWANO TOSHIAKI
IPC: H02P3/14
Filed: 1980-05-30
Abstract: PURPOSE: To reduce the number of equipment used in a main circuit by a method wherein a high speed current reducing device for regeneration is also used as a chopper shortening switch when a vehicle is on a power run.  
     CONSTITUTION: When the vehicle is on a power run, cam switches P1 and P2 are closed and current supply to a motor M is controlled by a chopper CH. When the revolution of the motor M increases to cause the current flow rate through the chopper CH to approach 1, a chopper shortening command signal closes a high speed current reducing device or breaker L3. Application of a brake closes cam switches B1 and B2 and the motor current is regenerated into a load LW via the high speed current reducing device or breaker L3. A large currency due to unsuccessful commutation by the chopper CH at the time of regeneration is reduced by the opening of the high speed current reducing device or breaker L3.

Title: Yc separator
IPC: H04N9/78
Filed: 1992-03-30
Abstract: PURPOSE:To easily obtain a picture with high resolution by adding a signal resulting from a video signal delayed by one horizontal scanning period only and a signal resulting from the video signal passing through an LPF with a prescribed cut-off frequency, thereby outputting luminance signal. CONSTITUTION:When a signal whose frequency is 14.32MHz is used for a clock signal used to transfer the charge of a CCD being the delay element of a one- horizontal scanning period delay element 3, the cut-off frequency of a low pass filter(LPF) 2 is set around 7MHz and the cut-off frequency of an LPF 4 is set around 5.5MHz for the purpose of band limit of an inputted video signal and elimination or the like of folding distortion and leakage component of a charge transfer clock of the CCD. Furthermore, the cut-off frequency of an LPF 9 is set around 15MHz and the LPF 9 has an equal delay time to that of the LPF 2. An adder 5 adds the output of the LPF 9 and the output of the LPF 4 resulting from the video signal delayed by one horizontal scanning period only to output a luminance signal having a prescribed frequency characteristic. Thus, the attenuation at the frequency of 7MHz is reduced.

Title: Production of friction material
Inventor: SUZUKI MASAMICHI
IPC: F16D69/00
Filed: 1984-04-13
Abstract: PURPOSE:To produce cheaply a friction material free of a problem of rusting without any change in frictional characteristics, by molding asbestos and an abrasion-resistant material together with a synthetic resin and bringing the molding into contact with water to decrease the amount of water-soluble substances in the asbestos. CONSTITUTION:Asbestos and an abrasion-resistant material (e.g., abrasion-resistant powder consisting of heat-cured cashew shell oil) are molded together with a synthetic resin (e.g., melamine-modified phenolic resin) into a desired shape and brought into contact with water to decrease the amount of water-soluble substances in the asbestos. Asbestos has a property of stiffening and undesirably changing its performances upon contact with water, but the properties of asbestos scarcely change in the above case, because it has already been molded. Conventionally, it sometimes happens that when an automobile is left undriven, its clutching operation becomes difficult because of the rusting of the clutch facing. By using a clutch facing formed from the above friction material produced cheaply without changing frictional characteristics, it is possible to start a car with smooth clutching operation even when the car is left undriven for a long period.

Title: Device for preventing production of excessive pressure in flexible film dam
Inventor: INOUE NOBUO
IPC: E02B7/20
Filed: 1981-05-20
Abstract: PURPOSE:To enable to perform an easy operation and maintenance of a device, by a method wherein, in a titled device for use with seawater dam at estuary, a water storage part is formed at an intake and exhaust system to and from a film dam, and a water storage part is placed underwater at the upstream side of the film dam. CONSTITUTION:If air is fed through an intake and exhaust pipe 7, a rubber dam 1 starts to rise up. If a water level of dammed water 11 is positioned higher than a forward end opening 10b of a pipe 10, a seal pressure in the intake and exhaust pipe 7 is brought to H for a head conversion. When the air pressure in the rubber dam 1 attains about a maximum allowable pressure, air is diffused into the air through the water 11 from the pipe 10. If rising of the rubber dam 1 is approximately complete, the intake and sicharge pipe 7 is reduced in an air amount flowing therein, and the pressure in the rubber dam 1 approximates to the pressure in the pipe 10. As a result, when an intake valve is closed, a blower 5, simultaneously, suspends operating, and this completes the rising of the rubber dam 1.
