Title: Laminate and its manufacture
Inventor: FUJII KENTARO
IPC: B29L9/00
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To obtain a light-weight plastic molding with a beautiful design formed on the surface by laminating a transfer layer or an insert sheet integrally on the surface of the moldings comprising a mixture of paper powder dispersed and mixed with a resin component at a specific ratio. SOLUTION: A decorating sheet is placed in an injection mold, then a mixture of 140-140wt.% of paper powder dispersed and mixed with a resin component is thermally melted and molded by injection into the mold. Consequently, a monolithic laminate of the decorating sheet and the mixture is obtained after cooling. The decorating sheet to be used is a transfer material or an insert sheet. The paper powder is crossings of papers including used ones. A crusher is used for crushing the paper, and a kneader is used for mixing the resin component with the paper powder and kneading these materials for uniform dispersion after adding the latter to the heat softened former. The kneaded mixture is pelltized or formed into a chip as a molding material.

Title: Sound multiplex video tape recorder
Inventor: OOTSUKA SUSUMU
IPC: H04N5/92
Filed: 1983-04-15
Abstract: PURPOSE:To convert the modulation output given to a TV from a VTR into a monaural signal to reduce a buzz by using a switching circuit which mutes sound and at the same time switches off a sound multiplex control signal at a variable speed mode. CONSTITUTION:The signal given from a 55.125kHz control signal oscillator 12 is applied to a mixer 4 via a multiplex control signal generating circuit 11. When a VTR is set in a variable speed reproduction mode (still, double speed, etc.), the oscillation is stopped for the oscillator 12 by a switching circuit 13. As a result, the signal given from the circuit 11 is also stopped in response to the muting of sound. Then no multiplex control signal is transmitted to obtain a monaural reproduction mode, and to reduce therefore the buzz.
Patent JP-S6390742-A (JP)
Title: Moisture indicator
Inventor: ALASAARELA ESKO
IPC: G01N/
Filed: 1987-03-19
Abstract: The invention relates to an optical device for measuring moisture in a substrate, in which device water is conveyed from the substrate along a porous absorption part (5) on a surface (4) of a prism so that is causes the critical angle of the total reflection to be changed thereon as a result of the change of the index of refraction. Another surface of the prism is dyed or patterned and covered in such a manner that it becomes visible only through reflection from the surface (4) when the surface is dry. When the surface (4) is moist, only the absorption part is visible through the viewing surface. The invention is advantageous in that due to the application of the principle of total reflection the change from an indication of the presence of moisture to an indication of the absence of moisture takes place sharply, not gradually.

Title: Air-fuel ratio control device for engine
Inventor: MATSUSHIMA MICHIO
IPC: F02D41/04
Filed: 1994-03-08
Abstract: PURPOSE:To prevent torque shock due to the switching of a set air-fuel ratio at the time when the engine load is high, and improve fuel consumption and output at the time when the engine load is low, by delaying the switching speed of the set air-fuel ratio when the detected engine load is high. CONSTITUTION:A set air-fuel ration, which differs for each of plural operating ranges, is set by an air-fuel ratio setting means P1. An actual air-fuel ratio is adjusted to become the set air-fuel ratio by an air-fuel ratio adjusting means P2. In such an air-fuel ratio control device, the engine load is detected by an engine load detecting means P3. As a result, when the detected engine load is high, the switching speed of the set air-fuel ratio is altered to be delayed by a switching speed altering means P4. Thus, the prevention of torque shock due to the switching of the set air-fuel ratio at the time when the engine load is high (when torque diffential is large), and the improvement in fuel consumption and output due to rapid switching of the air-fuel ratio at the time when the engine load is low (when torque differential is small), can be achieved.

The data of the memory 4 can be written by a memory read-write part 7 from outside or the electric characteristic data of the lighting discharge lamp can be written. The lighting of the discharge lamp having the different electric characteristic can be controlled by just replacing the electric characteristic data of the discharge lamp in the table memory.

Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To reduce engagement shock as it occurs when a clutch is engaged and to prevent clutch durability from being degraded when quick pressure boost control cannot be executed immediately after an engine has been restarted. SOLUTION: When it is determined, through a sequence (S380) of determining whether or not a quick pressure boost control can be executed, that it 'cannot be executed', an engine torque is dropped (S400) as compared with a time during which the quick pressure boost control can be executed.

Title: Differential amplifier gain adaptive type level shift circuit
Inventor: TAKAHASHI AKIRA
IPC: H03G3/10
Filed: 1986-03-25
Abstract: PURPOSE:To apply level shift corresponding to the gain of a differential amplifier by providing the differential amplifier for level shift using a bias of a constant current source of the differential amplifier as a noninverting input and using the inverting/ noninverting output of the level shift differential amplifier so as to control the shift of the level shift circuit connected to the input/output section of the differential amplifier for signal amplification. CONSTITUTION:In decreasing the value of a variable resistor 11, a current flowing to a constant current source is decreased and the gain of a differential amplifier is decreased, the collector potential of a transistor (TR) 7 is increased, the potential of an output signal terminal 27 and when the potential rise is large, the TR of the circuit connected to the next stage is saturated. Thus, when the gain of the differential amplifier is increased and the collector potential of the TR 7 is decreased, the input potential of the differential amplifier is shifted toward the low potential side, and when the gain of the differential amplifier is reduced conversely and the collector potential of the TR 7 rises, the potential at the output signal terminal 27 is shifted toward the low potential. Thus, the TR 7 or the TR of the circuit connected to the next stage is prevented from being saturated.
