IPC: G01N21/89
Filed: 1986-06-30
Abstract: PURPOSE:To eliminate noise produced in a detection signal by transmitting linearly polarized light through a film base by the use of flying spot system and reflecting the light to an incident direction. CONSTITUTION:The optical beam outputted from a laser luminous source 1 is inputted to a rotating polygon mirror 3 through a lens 2 by means of the flying spot system and scanned at right angle to a transit direction of the film base 4. The scanning beam is made incident on the film base 4 at a Brewster's angle beta in the state of linearly polarized light through a half mirror 5. The transmitted light is reflected at a concave mirror 6, and the reflected light is transmitted again through the film base 4, then it is reflected at the mirror 5 and inputted to a detecting part 7 having photomultiplier to be detected the intensity of the transmitted detection light. Then in order to compensate the detection signal noise produced by the film base 4, the difference to a compensate data prepared previously in an operation means is to be obtained, or making the mirror 5 as a stripe mirror 9 consisting of a half mirror part 9a and a metallic mirror 9b to eliminate the noise.

Abstract: PURPOSE:To realize the stabilization of min. light receiving sensitivity to the change in temp., by negating a dark current component by using an element having a same reverse direction current-voltage characteristic other than a light receiving element. CONSTITUTION:A light receiving diode 6, a temp. compensating element 7 having the same quality and temp. characteristic as said diode 6 or same thereto but prevented from the incidence of light, current detecting resistors 8, 9, overcurrent preventing resistors 10, 11 and bias power sources 12, 13 are provided. In the change in temp. is generated when respective voltage drops are made equal in such a state that the light to the light receiving diode 6 is blocked, a dark current changes but a change ratio is same and min. light receiving sensitivity does not change while, when light is incident to the diode 6, a current corresponding to light is flowed to the resistor 8 to obtain voltage receiving no effect of temp. By this method, the dark current of the light receiving diode is stabilized to the change in temp. and the stabilization of min. light receiving sensitivity can be realized.

Title: Program timer
Inventor: ITOU MASAO
IPC: G05B15/02
Filed: 1978-12-12
Abstract: PURPOSE: To enable program timer operation from the initial set day in a program timer by comparing the start and end set times repeated in every day with present time to thereby control a timer operation.  
     CONSTITUTION: When the program time starting and ending times are set, the set times are written in the RAM209 of a microcomputer 200 for controlling the execution of a program. The storage in the RAM209 is read at the present time written in response to clock to allow a comparator C to compare the set time with the present time as to their magnitude to determine whether the program set with the present time is ON or OFF time together with erroneous set. In case of ON time it immediately becomes program time state without waiting next day in response to the output of the comparator C in case of day period program. Accordingly, the revision of setting the program and the program therefor are immediately responded to readily operate the change of the set program or the like.

Title: Exhaust device engine
Inventor: EGUCHI NOBUJI
IPC: F02B27/04
Filed: 1990-06-13
Abstract: PURPOSE:To enable afterburing of unburnt components in exhaust gas by forming a throttle passage at an exhaust port, and fitting a throttle valve for throttling the throttle passage, to an exhaust valve, thereby throttling the throttle passage by the throttle valve during the period from the opening starting time to the specified lift of the exhaust valve. CONSTITUTION:A throttle passage 31 provided at one part, particularly on the cylinder 11 side, of an exhaust port 22 is formed by providing the exhaust port 2 with steps. In correspondence with this throttle passage 31, a throttle valve 32 is fitted to the step part of an exhaust valve 24. When the exhaust valve 24 is opened by a cam during the operation of an engine, the throttle passage is throttled by the throttle valve 32 during the opening stroke of the exhaust valve 24. The flow of exhaust gas is therefore temporarily contracted from the opening starting time to the intermediate time of the exhaust valve 24 to perform internal exhaust gas recirculation. The formation quantity of nitrogen oxides is thereby reduced, and also the internal temperature of a cylinder 11 becomes temporarily high to enable the afterburning of unburnt fuel and particulates in exhaust gas.

Filed: 1993-06-25
Abstract: PURPOSE: To acquire an execution form in a CMOS by generating a prescribed output signal at the time of receiving a receiving pulse that has the same polarity or the opposite polarity to a 1st receiving pulse, following it. CONSTITUTION: A receiver circuit 10 forms a band filter, based on four sample data counters 16, 18, 26 and 28 and eliminates a signal that does not exist in a prescribed frequency range through filtering. The circuit 10 receives a P pulse from a comparator 12, and when the P pulse has a pulse width that is larger than the smallest pulse that has been preliminarily selected by the P pulse, the counter 16 generates an active P pulse. Also, the counter 18 receives an N pulse, and when the N pulse has a pulse width that is larger than the smallest pulse width that has been selected by the N pulse, the counter 18 generates an active N pulse. When it is smaller than the pulse width that is created and selected by the counters 16 and 18, the counters 26 and 28 generate an active length pulse output signal, respond, and trigger receiving data.  Then, an embodiment form can be acquired only with a CMOS.

Abstract: PURPOSE:To automatically prepare diagnostic data having a high detection rate at the time of diagnosing an input flip flop group, output flip group, and a combinational circuit surrounded by the groups by providing a signal route exclusively used for diagnosis only. CONSTITUTION:Fault occurring at a faulty point 18 in a combinational circuit 2 is propagated to an input FF group 1 and further propagated to a selector circuit 6 from a gate output point 19 which connects the group 1 to a peripheral section 14 through a signal route 20 exclusively used for diagnosis only. The propagated results of the signal of the circuit 2 are stored in an FF group 7 for diagnosis by selecting the internal signal of a logical section 13 as the input of the selector circuit 6 and turning off a shifting operation switching signal 17 based on a select control signal 9. Then, the value stored in the FF group 7 is fetched from a shift-out edge pin 11 by turning on the signal 17 and sending shift clock signals 15 and 16 to the FF group 7. Therefore, the signal propagating results of the combinational circuit 2 can be observed from the pin 11.
