Title: Air valve
Inventor: MORITA EIJI
IPC: F16K24/00
Filed: 1990-02-02
Abstract: PURPOSE:To regularize the required force at time of air hole opening or closing by making it so as to materialize a specific relationship between each distance up to a valve element and both first and second push rods from a link lever fulcrum and a sectional area of the air hole and each pressure receiving area of both first and second diaphragm pistons. CONSTITUTION:A weight 8 is hung from an endpoint 6 of a link lever 5 via a first push rod 7 which is surrounded by a first diaphragm piston 9. In addition, a valve element 12 is hung from a sling point 11 of the link lever 5 and an air hole 13 is opened or closed, while a second push rod 15 is suspended on an endpoint 14, receiving some action of a second diaphragm piston 16. When each distance up to those of valve element 12, push rods 7, 15 from the fulcrum 4 is set to La, L1 and L2, while a sectional area of the air hole 13 is set to Aa, and each pressure receiving area of these first and second diaphragm pistons 9, 16 to A1, A2, respectively, the relation in an equation I is set so as to be almost materialized. With this constitution, such a force as closing the air hole 13 with the valve element 12 moved comes only pressing force by dint of energizing force overcoming gravity of the weight so that it becomes constant.

Filed: 1984-02-10
Abstract: PURPOSE:To improve a knocking detecting precision by detecting the engine vibration above a prescribed level from the starting time to the finishing time of the knocking detection based on the period of a basic igniting signal corresponding to a basic igniting spark advance. CONSTITUTION:A base igniting signal generating period is determined by a basic igniting signal generating time by a timer 8e incorporated in a microcomputer 8 according to the judgement of a basic igniting signal generation by a pick up coil 14 opposing to a signal rotor 12 in a spark advance apparatus and a signal similar to the last time stored in a RAM8c. The base igniting spark advance angle is read from a ROM, and the starting time and the finishing time of the knocking detection and a variation starting time, etc. corresponding to a judging level variation starting crank angle are determined accurately. The comparing standard level through the computer 8, a D/A converter 10 in the knocking time and an engine vibration level from a knocking sensor 2 are compared by a comparator 6 to judge the knocking. The knocking detecting precision is improved by the knocking time determined accurately.

A function between the power consumption 'P' of a fan motor 1 and the efficiency of it is previously set in a corrector-comparator 8. It automatically controls the efficiency of an exhaust fan so as to be constant by controlling a power controlling circuit 4 by comparing an input voltage with a controlling voltage 5, and at the same time it corrects the efficiency of a fan by correcting the output value of a multiplier 10 by giving a correction 'etaP' to it, so that the optimum air/fuel ratio can be obtained over the whole variable range of combustion rates.

IPC: H03K17/78
Filed: 1987-02-06
Abstract: PURPOSE:To make a resonance circuit large in capacity unnecessary, by detecting a reception signal by differentiating and amplifying it. CONSTITUTION:An optical signal received by a photodetector 1, after being converted to an electrical signal and differentiated by a differentiation circuit of a capacitor C1 and a resistor R1, is amplified by an amplifier 2.

Title: Telescopic pole device for vehicle
Inventor: YOSHIDA KOICHI
IPC: B60Q1/32
Filed: 1995-01-19
Abstract: PURPOSE: To prevent air from going in and out of a housing caused by pressure difference acompanying expansion and contraction of a pole. CONSTITUTION: A drive cord 8 is passed inside a telescopic pole 1 provided with an indicating lamp 19 on the extreme end, and a winding drum 5 for winding or unwinding the drive cord 8 and a motor 14 for driving the winding drum 5 to rotate normally or reversely in both directions are received in a housing 3 connected to the lower end of the telescopic pole 1. The detachably fitting port 3b of the motor 14 in the housing 3 is covered with a cap 34 made of synthetic rubber having a flexible thin wall part 34a capable of being bent in the inner and outer directions. When the telescopic pole 1 is expanded or contracted, the pressure in the housing 3 is intended to vary, but the flexible thin wall part 34a of the cap 34 is bent so as to keep pressure balance between the inside and the outside.  Consequently, the inner pressure of the housing 3 is not lower than the outside, and hence water content does not remain in the housing because air does not go in and out against the housing 3.

Abstract: PURPOSE: To operate the sample-and-hold operation with high accuracy by providing a means applying a potential of an input signal to a hold capacitor, transistors(TRs) in emitter follower operation, an amplifier and a means supplying a base current to the TRs to the sample-and-hold circuit. CONSTITUTION: When a clock signal 14 is at an H level and an inverted clock signal 12 is at an L level, an input level of an analog signal charges up a hold capacitor 11. Since a current of a constant current source 344 of a differential amplifier 301 flows to a TR 341, an emitter current of a TR 215 and an emitter current of a 341 in a leakage current compensation circuit 201 are made equal to each other. The current 14 is supplied to a current mirror circuit, then a current 15 nearly equal to the current 14 is outputted to a terminal 241 and fed to a base of the TR 341. As a result, a leakage current from a capacitor 11 by a base current of the TR 341 is compensated by a current from the circuit 201 and then the sample-and-hold circuit is operated with high accuracy.

CONSTITUTION:At the position of no voltage impression, a light from a backlight 1 is transmitted through a color filter 14 and the 1st polarizing plate 12, but optically polarized by the liquid crystal 8 in a TN type liquid crystal cell 2, so that the light can not be transmitted through the 2nd polarizing plate 13 and becomes dark background. Since the part excluding the display pattern on the inside of a display base 4 is covered with the black mask layer 9 and the black two-color coloring matter 7 is contained in the liquid crystal 8, a color due to light interference in the cell 2 or the color of the color filter 14 is canceled by the mask layer 9 and the two-color coloring matter 7 and a color close to pure black can be obtained. In addition, the background becomes dark such that the border between a red area 14a and a blue area 14b of the color filter 14 can not be distinguished and the brightness of the background part is uniform even if the polychromatic color filter 14 is used.
