Title: Oil-refilling system for torque converter in automatic speed change gear
Inventor: SUZUKI HOSEI
IPC: F16H61/64
Filed: 1982-03-12
Abstract: PURPOSE:To enable to speedily raise a feed pressure for a torque converter, by a method wherein a negative pressure exerted on a vacuum-controlling diaphragm of an oil pressure controlling valve is maintained to be low irrespectively of a suction pipe negative-pressure, at the time of cold starting. CONSTITUTION:At the time of stating an engine, when the gear is shifted into a neutral or parking range, an inhibitor switch 10 is in a closed state. Therefore, until the engine is warmed up, a closed state of a temperature-controlling switch 12 causes a signal to be impressed on a solenoid 8a, thereby energizing the solenoid 8a to change over a three-way valve 8 so as to maintain a vacuum chamber 2a in the communicated condition to the atmoshere, whereby the chamber 2a is prevented from being communicated to the suction pipe side through a line 3. Under this condition, the internal pressure in a line 4 is raised by driving a pump 5, concurrently with which the refilling of an oil into the torque  converter 7 proceeds speedily.

Title: Method and device for generating vector coordinate from dot pattern
Inventor: MOCHIZUKI YASUSHI
IPC: G06T7/60
Filed: 1994-02-14
Abstract: PURPOSE:To extract vector coordinates for faithful scaling to an original dot pattern by expanding the dot pattern even times at the time of extracting outline points from the dot pattern. CONSTITUTION:A scalable font corresponding to an input character code is stored in a font ROM 6, and an incorporated RAM 7 includes a work memory used at the time of generating vector coordinates of the dot pattern. A CPU 3 takes the dot pattern, whose vector coordinates should be extracted, into this work memory and extracts outline point strings of the outer outline and the inner outline into the work memory by the outline point tracing method. Next, the CPU 3 acquires the start points of outlines and corrects respective outline point strings by looping the same number of times as outlines and expands outline points even times. The CPU 3 performs the coordinate correction processing based on the tracing direction as direction information of expanded outline points. Thus, outer outline points as well as inner outline points are converted at regular intervals.

IPC: H03K19/088
Filed: 1982-03-17
Abstract: PURPOSE:To pevent the generation of waveform distortion appearing in an output signal, by forcibly discharging the charge accumulated in an output transistor. CONSTITUTION:When one of input signals supplied to terminals T1, T2 attains to L level, collector voltage of a transistor (TR) Q2 attains to H level, a TRQ3 turns on, and a part of an emitter current is reduced to a base current of a TRQ4. Accordingly, the TRQ4 turns on, and no base currnt is supplied to a TRQ5, so that it turns off. As a result, an output level of an output signal appearing in a terminal T4 is switched to an H level from an L level. When the TRQ3 is switched to an on-state, a base current is supplied to a TRQ6 through a resistance R5. Subsequently, to the collector of the TRQ6, base voltage VBE of the TRQ5 is supplied as collector voltage. Accordingly, from the instant when the Q3 turns on, the TRQ6 turns on by synchronizing with the Q3. In this way, discharge of the charge is executed.
