Title: Electronic timepiece
Inventor: USHIKOSHI KENICHI
IPC: G04G5/00
Filed: 1978-09-21
Abstract: PURPOSE: To improve the manipulating property of an electronic timepiece, by indicating a battery voltage fall detection function or the like together with the preparing state of another function.  
     CONSTITUTION: Usually, a signal is applied from a frequency division circuit 12 to a driving circuit 13 to drive hands 15. When the signal of a switch signal circuit 27 for correction of time difference or a battery voltage detection circuit 16 becomes HIGH, an unusual wave form generation circuit 18 produces a signal to move the hand by two seconds each time. The adjustment of the hands is started by actuating a switch 1 after another switch 3 is pressed for correction of time difference. At the beginning or end of the actuation of the switch 1, an updown counter 28 is switched to up-operation 30 or down-operation 31 to quickly advance the hands by a time cost for time adjustment.

Title: Display device
Inventor: MATSUMOTO TOSHIO
IPC: G09G3/36
Filed: 1992-05-11
Abstract: PURPOSE:To reduce the cost of a liquid device as a whole. CONSTITUTION:A liquid crystal display device (LCD) 11 is driven by 480 data signal lines 12 and 640 scanning signal lines 13 and displays video data in accordance with the VGA spec. A picture element 14 located at a cross point of the lines 12 and 13 consists of a thin film transistor(TFT) 17 and a picture element electrode 18. Signals of display data are given to the data signal line 12 by a data signal line driving circuit 15. When one of the scanning signal lines 13 is selected by a scanning signal line driving circuit 16, picture data are displayed by the crystal near the picture element electrode 18. The cost to drive the lines 12 is larger than the cost to drive the lines 13. Since the number of the lines 12 is less than the number of the lines 13, the cost of the display device as a whole is reduced.

IPC: B24B37/00
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To measure the worn amount of a grinding wheel or polishing cloth accurately without the drop of the efficiency of the grinding work of a wafer. SOLUTION: As the worn amount of cup type grinding wheels 54, 64 is measured by a non-contact type worn amount measuring instrument 68 consisting of a floodlight 70 and optical receiver 72, the worn amount measuring instrument 68 can be fixingly arranged to the position in which the polish of the wafer 26 by the cup type grinding wheels 56, 64 is not disturbed.

Title: Material for high pressure fuel injection pipe and manufacture thereof
Inventor: USUI MASAYOSHI
IPC: C23C8/04
Filed: 1978-09-26
Abstract: PURPOSE: To prevent an attack due to cavitation on the internal wall surface of a small diameter, thick walled pipe, either by quenching the pipe from outside after it is carburized at the internal wall and is heated as a whole, or by allowing it to cool after it is carburized and its inner wall alone is heated by high frequency induction.  
     CONSTITUTION: A small diameter, thick walled steel pipe 1 for charging fuel to a diesel engine is carburized at the inner wall side 4. The pie is heated as a whole, it is then cooled as fast as possible from outside. Or after the carburizing as described above, the inner wall alone of the pipe is heated rapidly by high frequency induction, then it is allowed to cool. By the treatment, the hardness of the thick walled part 2 of the pipe 1 is increased to give a hardness distribution of about HV 150 to HV 230 from the outside to the inside. With increase in hardness, the attack due to cavitation is prevented efficiently because a residual compressive stress layer 5 of high carbon content is formed in the peripheral direction including the longitudinal axis direction, and a dense crystal structure is formed.

Abstract: PURPOSE:To search automatically at a high speed a practical path by executing a temporary wiring between a designated source and target by using a computer, applying and connecting a prescribed pattern, and using a mesh just before an obstacle, as a new source, when the obstacles exists. CONSTITUTION:When an operator designates a source S1 and a target T1 which are two points to be connected, a computer applies a pattern P1 between these two points and executes a temporary wiring.

Title: Flip-flop circuit
Inventor: KIMURA HIROMICHI
IPC: H03K3/2885
Filed: 1979-09-14
Abstract: PURPOSE:To make it possible to provide the function of waveform shaping while increasing a noise margin by feeding antiphase output signals of FF back to either base of data writing transistor. CONSTITUTION:To the base of data writing transistor TRQ4', the collector of TRQ3' is connected to provide positive feedback. Namely, when data input terminal 1' of FF is at ''L'', TRQ4' turns on and as the voltage of terminal 1' is gradually increased from the point mentioned above, a current shunt to TRQ3' starts on the forward base-emitter biasing of TRQ3', so that TRQ4' will rapidly be turned off according to characteristics of feedback to the base. Namely, input-output voltage characteristics of the data writing part vary as shown by curve 50 and even if a waveform slow in rise and fall is applied to terminal 1', a shaped output can be expected while the noise margin is made large through the hysteresis effect.
