Title: Knocking control device for engine
Inventor: MIYAMOTO KOJI
IPC: F02P5/152
Filed: 1987-04-20
Abstract: PURPOSE:To improve durability and reliability of an engine by detecting an engine temperature to lessen the maximum correction amount when an engine is cold, whereby sudden lowering of engine output is restrained, and when true knocking occurs, the knocking is restrained. CONSTITUTION:When an engine cooling water temperature is less than about 85 deg.C, there is the possibility of misdetecting noise caused by strong contact of a piston 4 with a cylinder 3 by a knock sensor 35, so that when a controller 37 receives a detection signal of a cooling water temperature sensor 40, a drop width (correction amount) of a duty ratio signal value of a duty solenoid valve 26 is changed and reduced from 100% to 50%. Thus, the maximum supercharging pressure becomes the intermediate supercharging pressure (PH+PL)/2 between supercharging pressure PH corresponding to 100% and super-charging pressure PL corresponding to 0% and it will not be lowered to the minimum value, so that sudden lowering of engine output can be prevented. Furthermore, even if true knocking occurs, as the maximum supercharging pressure is lowered from the supercharging pressure value PH to supercharging pressure value (PH+PL)/2, knocking can be prevented.

Title: Liquid crystal display device using diffuse reflection type hologram
Inventor: HOTTA TAKESHI
IPC: G02F1/1335
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To make a display picture easy to see and to write by making the position of a scattering reflection surface to be reproduced from a diffuse reflection type hologram and the position of the liquid crystal layer of a liquid crystal display element coincide to confrom the scattering reflection surface with the liquid crystal layer or a touch panel surface. SOLUTION: The scattering reflection surface 2 recorded in a diffuse reflection type hologram 1 is flcated from a hologram surface to cincide with the liquid crystal layer 45 of a liquid crystal display element 40. As a result, when illiminating lights 32 are made incident from the display side of the element 40, lights duffusingly reflected on the hologram 1 by being passed through transparent pixels are diffracted as scattered lights 33 Just as going out only in angle ranges θs conforming to observation areas of a liquid drystal display device from the scattering reflection surface 2. Thus, a bright display is made possible without using a self-emitting backlight in a bright place.  Moreover, since the scattering reflection surface 2 coincides with the liquid crystal layer 45 being the display surface of the liquid crystal display device, a prallax is not present in between a display picture and the scattering surface and the display picture is made to be extremely easy to see.

Title: Production of dialkylphenol
IPC: B01J21/16
Filed: 1992-03-25
Abstract: PURPOSE:To prevent a raw material alkylphenol from solidifying in a condenser, a line and a valve in distilling and recovering the raw material alkylphenol in producing a dialkylphenol using a high-melting monoalkylphenol and an olefin. CONSTITUTION:Reaction is carried out by using a reactional solvent distilling together with a high-melting monoalkylphenol. After completing the reaction, the unreacted raw material monoalkylphenol is distilled and recovered together with the reactional solvent. The condensation of the low-melting monoalkylphenol in a condenser, a line and a valve is eliminated in the distillation by using the reactional solvent having the boiling point similar to that of the high-melting monoalkylphenol. Thereby, this method is effective in simplifying the equipment.

Title: Output circuit for pwm inverter
Inventor: KISHI TORU
IPC: H02M7/537
Filed: 1993-04-23
Abstract: PURPOSE:To reduce the control error and power consumption of the output circuit by constituting a first and second IGBTs in such a way that the IGBTs are not substantially turned on at the same time and their safety can be secured, and then, the floating time can substantially become '0'. CONSTITUTION:The gate of a first N-channel IGBT l is connected to the emitter of a second P-channel IGBT 2 so that the potential difference between a gate signal voltage 50 and motor winding terminal voltage 51 can fall within a fixed range and no shortcircuit state can be generated between the (+) and (-) terminals of a main DC power source due to simultaneous flow of electric currents to the IGBTs 1 and 2. When a motor releasing signal 156 instructs a low level, NAND means 106 and 107 become high in level irrespective of a switching command signal 42 and the base signals 123 and 29 of a PNP transistor 119 and transistor 29 respectively become high and low in level. As a result, the gate signal voltage of the IGBTs 1 and 2 becomes the same potential as the terminal voltage 51 through a resistor 105 and the IGBTs 1 and 2 are set to freely running states. When the signal 156 instructs a high level, the IGBTs 1 and 2 are shifted to another states.

Patent JP-H05296908-A (JP)
Title: Gas sensor
Inventor: MATSUNO GEN
IPC: G01N29/00
Filed: 1992-04-17
Abstract: PURPOSE:To simultaneously measure the concentration of a gas and the distribution factor of the gas against an adsorption film with one gas sensor by combining a pipe with an internal surface coated with the adsorption film with two surface acoustic wave (SAW) elements. CONSTITUTION:When a gas to be measured is sucked through an intake 3 for gas to be measured, a gas adsorption film 14 starts to adsorb the molecule of the gas. A computer 6 measures decreases in oscillation frequency of SAW elements 13a through an oscillator 4 and frequency counter 5. On the other hand, the rise of variation of the oscillation frequency is delayed, since the component of the gas is adsorbed in the film 14 in a pipe 1 having a length L. In other words, the pipe (gas sensnr) 1 acts as the column of gas chromatography. The computer 6 calculates the concentration of the gas from a specific expression. For a multicomponent gas, each kind of gas can be separated and distribution factors to each component can be measured, since the outputs of the elements 13b are outputted in step-like states.
