Title: Method for eliminating nitrogen oxide in exhaust gas of diesel engine
Inventor: KOBAYASHI MOTONOBU
IPC: F02B3/06
Filed: 1989-02-02
Abstract: PURPOSE:To eliminate efficiently nitrogen oxide at a high level by controlling the flow rate of ammonia on the basis of the measured values of engine output, exhaust gas temperature, and intake air temperature and supplying ammonia into exhaust gas. CONSTITUTION:Respective signals outputted from an output meter 2 or an output proportional signal transmitter 2a, an exhaust gas temperature detector 5, and an intake air temperature detector 13 are inputted into a computing unit 14 in response to the load quantity of an engine main body 1. The total quantity of discharged nitrogen oxide is calculated in the computing unit 14, and this signal is inputted in a proportional setting device 15, then an ammonia quantity to be supplied by an ammonia/ nitrogen oxide ratio which is set beforehand by the proportional setting device 15 is decided. The output of the proportional setting device 15 is inputted into an ammonia flow rate controller 16 as an ammonia flow rate signal, and opening/closing of an ammonia adjusting valve 10 is controlled, so that the ammonia quantity mixed in exhaust gas flowing into a reactor 7 is controlled. It is thus possible to respond quickly to rapid changes in exhaust gas nature and rapid changes in nitrogen oxide quantity in association with the fluctuation of an engine load.

Abstract: PURPOSE: To enable setting of alarm time to be made in a short time by using the second hand and minute hand at the time of current time displaying as the minute hand and hour hand at the alarm time displaying in plural time system display of the current time and alarm time.  
     CONSTITUTION: When an alarm is going to be set at 7:00 while the current time is indicating, e.g., 4:10:0, first a crown 3 is operated to send a signal to a control circuit 20 which then causes a selection circuit to stop the selection of the driving signals. The minute hand 5 of the current time display is then read as the hour hand at the alarm time setting and the second hand 4 is read as the minute hand, and the quantity corresponding to the time difference 2 hours 50 minutes between the current time and alarm time is fast fed. At this time, the differece of 2 hours 50 minutes is indicated by the hour hand 5 and minute hand 4 for the alarm time display and the second current time of 4:12:50 is being displayed. Thereafter, the hands begin to clock the normal time as the current time display hands and an alarm is given after lapse of 170 minutes.

Filed: 1980-03-03
Abstract: PURPOSE:To make a testing transformer small-capacity and make a high voltage generator small-size and cheap and reduce the noise from the commercial power source, by using an ultralow frequency to reduce the charging current to the device to be tested. CONSTITUTION:High frequency oscillator 1 is the oscillator of, for example, 100kHz, and its high frequency is amplified by buffer amplifier 2, and the output is supplied to the input side (stator) of rotary transformer 3. The coupling degree of the output side (rotor) of transformer 3 to the input side is changed by rotation, and the output voltage is increased and reduced. If the rotor of transformer 3 is rotated once for one second by motor 4 and decelerator 5, modulation wave 3' modulated by 100kHz is obtained. Further, if rotary transformer 7 is rotated once for 10min by motor 8 and decelerator 9, the output voltage is increased from 0 gradually and becomes maximum after 10min. This voltage is amplified and is boosted by boosting transformer 11 and is rectified by rectifier 12 to obtain an ultralow-frequency high-voltage test voltage.

IPC: H01L29/84
Filed: 1994-02-23
Abstract: PURPOSE:To provide a semiconductor acceleration sensor enabling accurate acceleration detection to be carried out by reducing deflection of its flexible portions. CONSTITUTION:Four piezoresistances R1-R4 are formed on the surface of a pair of flexible portions 3 each of which is connected to a weight portion 2 at one end. The paired flexible portions 3 each have two of the piezoresistances R1-R4 which are formed in strips as seen from above a sensor portion A. A passivation film 5 is formed on the surface of the sensor portion A including the flexible portions 3. The length L of each flexible portion 3 from a support 4 to the weight portion 2 is approximately the same as that of those piezoresistance R2, R4 which are formed along the longitudinal direction of the flexible portions 3. Therefore, deflection of the flexible portions 3, caused by a difference in thermal expansion rate between the passivation film 5 and the flexible portions 3, can be reduced by reduction in the length of the flexible portions 3.

Title: Torsion damper
Inventor: KAMINAGA SEIJI
IPC: F16H45/02
Filed: 1983-02-18
Abstract: PURPOSE:To decrease frictional resistance, by preventing the movement in the diametric direction of a resilient member only by the end parts in the peripheral direction of a housing part so as to eliminate the contact with the resilient member by the other part except said end parts, in the case of a torsion damper for use of vehicle or the like. CONSTITUTION:A torsion damper, in which a spring 19 is arranged in a housing part 18 formed by penetrating input and output members 12, 13 and both ends in the peripheral direction of the spring 19 are respectively adapted to both ends of the housing part 18 when the torque is transmitted, performs the damping action by deforming the spring 19. In both end parts in the peripheral direction of the housing part 18 in any one of said input and output members, a circular arc shaped preventing part 20, which oppositely faces to an external diametric side end of the spring 19 and prevents the movement in the diametric direction of the spring 19, is formed around the center of rotation of the input and output members 12, 13 serving as the center, while a circular arc shaped relief part 21 is formed, avoiding the contact with the spring 19. In such way, decreasing the frictional force at relative angular displacement between the input and output members so as to decrease a change of width of hysteresis torque, wearing of the spring is reduced, thus durability of the torsion damper can be improved.

Abstract: PURPOSE:To obtain a fine MOS device by eliminating the generation of bird heads at the time of selective oxidation by a method wherein an Si3N4 film is stably left only on the side surface of the aperture of an Si substrate. CONSTITUTION:An SiO2 film 22 and an Si3N4 film 23 are superposed on the P type Si substrate 21, then the films 23 and 22 are opened by applying a resist mask 24, and when the substrate 21 is slightly etching-removed, the side surface is also etching-removed. Next, an aperture 21c is vertically provided by reactive ion etching, then B ions are implanted, and accordingly a channel stopper 25 is formed. An Si3N4 film 27' is provided over the entire surface by removing the mask and covering the aperture part with a thermal oxide film 26. An Si3N4 film 27' is left on the side surface of the aperture in self-alignment by reactive ion etching. Next, an SiO2 28 is formed by selective oxidation. Since bird heads are hardly generated, and a very deep field oxide film and a channel stopper are formed by this method, a fine MOSFET which has very high density and high accuracy and does not have the effect of narrow channel can be obtained.

Abstract: PURPOSE:To eliminate jitter from a transmission signal by providing a signal detector set by a start code in a reception signal and reset by a stop code and inputting a timing signal extracted from the reception data to a digital phase controlled oscillator only during the set period of the detector. CONSTITUTION:The input section of a DPLL (digital phase controlled oscillator) 104 is provided with an input block gate circuit 108 to block the input of the timing signal from a tuning circuit 102 to the DPLL in case the stop code of the reception signal is detected. The gate signal for the input block is given from the signal detector 107 set by detecting the start code at the head of the reception signal and reset by detecting the stopper code at the end of the reception signal, the gate signal brings the blocking gate into the passing state during the set period, that is, the DPLL is locked to the timing of the reception signal, the block gate blocks the timing of the reception during the reset period to make the DPLL run freely. Thus, the clock at the head of the transmission signal 118 from the data transmission section 106 has no jitter in the transmission clock for transmission data because the DPLL is run freely.
