Title: Optical reader
Inventor: TSUKADA MINORU
IPC: H04N5/335
Filed: 1989-09-19
Abstract: PURPOSE:To simplify the constitution by connecting plural photoelectric conversion elements to a switching means in common, driving sequentially light emitting elements so as to input only a signal from a photoelectric conversion element group receiving light to the switching means. CONSTITUTION:Analog switches SP11-SP1m are sequentially driven at a lighting period of a light emitting section L7 and only a signal from photodiodes PD51- PD5m is read. For example, the photodiode PD 11 is connected to the analog switch SP11 in this case, but no new light incidence is applied to the group P1 after the radiation of a light from an original by the preceding lighting of the light emission section L1 and the charge in capacitors C11-C1m is charged again at the preceding read of the signal. Thus, the input of the signal from the photodiode PD11 is prevented. Then the constitution is simplified in comparison with the case of controlling the photoelectric conversion element group by the switching means individually.

Filed: 1989-09-20
Abstract: PURPOSE:To attain fast analysis of numerical values by resolving an external circuit equation firstly at the time of analyzing the transient characteristic of an element unified integrally with an external circuit by numerical simulation. CONSTITUTION:The element whose transient characteristic should be obtained is a MOS transistor S, and the external circuit consisting of a resistance R, an inductance L, a diode D, and a power source E is connected between its source and drain electrodes.

Title: Valve system for engine
Inventor: SHIRAI EIJI
IPC: F01L13/00
Filed: 1992-09-14
Abstract: PURPOSE:To miniaturize an entire valve system by constituting a lifter with a body, a slider engaged with a high speed cam over a width equal to that of the latter, a spring, a pin for regulating the relative movement between the body and the slider, and a rotary mechanism. CONSTITUTION:A lifter 20 does not rotate due to cooperation between a plate 15 and a rotation preventing groove 51, and pins 41 to 14 can regulate the relative movement between bodies 30, 32 and a slider 37. A high speed cam 12 is always engaged only with the top surface of the slider 37 while low speed cams 13, 14 are always engaged with the top surface of the body 30. When the relative movement between the body 30 and the slider 30 are regulated, the high speed cam 12 engaged with the slider 37 causes the lifter 20 to open and close intake and exhaust valves. Meanwhile when it is not regulated, the low speed cams 13, 14 engaged with the body 30 causes the lifter to open and close the intake and exhaust valves. Since the width of the slider 37 is equal to that of the high speed cam 12, it is possible to miniaturize the entire valve system.

Abstract: PURPOSE:To obtain strobe data by detecting the secondary electrons in case of precharging in a reference phase phi0, sequentially obtaining an addition average, and detecting the saturation of the precharge when the change rate becomes smaller than the set value to finish the precharge. CONSTITUTION:The accumulated output of a digitized accumulator 26 of the secondary electron signal is divided by a divider 29 by the output of a counter 30 to obtain an addition average, which is stored in the second register 33 through a changeover switch 31, and compared by a comparator 34 with the previous set value stored in the first register 32.
