Patent JP-H041409-A (JP)
Title: Silencer
Inventor: NAKAJIMA HIKARI
IPC: F01N1/02
Filed: 1990-04-16
Abstract: PURPOSE:To make resonance frequency follow changeably a change in the noise frequency of fluid for effectively silencing sounds over the whole frequency range by bisecting the interior of a main body with a movable member elastically supported by an elastic member having a non-linear spring constant to compose and expansion chamber of one chamber and a resonance chamber of the other. CONSTITUTION:Exhaust from an engine flows from an inlet pipe 5 into an expansion chamber 3 to be expelled from an outlet pipe 6 to the atmosphere. The increase of exhaust pressure F along with the increase of the rotational frequency of the engine urges a free pitch 2 against a spring 8 to reduce the volume V of a resonation chamber 4. Since the spring 8 is of a non-linear property, the volume V is reduced to the inverse multiple of the increase multiple of the exhaust pressure F. Thus, resonance frequency f is increased linearly to the increase of the exhaust pressure F, i.e. the rotational speed of the engine to change in the same way as exhaust noise frequency. Thus, the exhaust noise of frequency in which a noise amount reaches a peak irrespective of the rotational speed of the engine is effectively silenced so that a high silencing effect can be held over the whole rotational range of the engine.

Title: Form control equipment of reflecting mirror, form control method and aligner
Inventor: TAKEUCHI HITOSHI
IPC: G03F7/20
Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To adjust surface temperature distribution of a reflecting mirror, and restrain thermal deformation to the utmost, by a method wherein a temperature adjusting equipment heats or cools at least partly the surface of the reflecting mirror, on the basis of detection results of a detection equipment. SOLUTION: An infrared radiation detector 105 measures the surface temperature of a reflecting surface, and outputs the result to a temperature distribution analyzing part 106. On the basis of the judgment result outputted from the analyzing part 106, a temperature control part 104 heats partly the rear of a reflecting mirror M2 with a heater 101. Since the reflecting mirror M2 is thin, the corresponding position of the reflecting surface is also heated by heating the rear. The temperature of the reflecting surface is detected by the infrared radiation detector 105, and the so-called feedback control is performed wherein the heating amount of the heater 101 is adjusted by a temperature control part 104.  By heating a relatively low temperature part of the reflecting surface in the above manner, the temperature of the reflecting surface is uniformly maintained, so that the local thermal deformation is prevented and the form of the reflecting surface, i.e., the flatness is precisely maintained.

IPC: G01C22/00
Filed: 1999-04-06
Abstract: PROBLEM TO BE SOLVED: To provide a new vehicle-speed detecting system whose performance exceeds that of a conventional vehicle speed sensor which causes a detection error due to the slip of a wheel. SOLUTION: Markers 2 in which resonators resonated with raio waves in a medium-wave to high-wave band of 100 to 500 kHz are built are buried at equal intervals in the center of a road traffic lane 1. An antenna 4 which can transmit the radio waves and a plurality of antennas 5, 6, 7 which can receive the radio waves are installed at a vehicle 3 in three places, i.e. in the right, the left and the center, of the front bumper. The radio waves are transmitted from the transmitting antenna, and the radio waves which are reflected from the markers 2 are received. Thereby, the markers 2 can be detected with good accuracy. Since the interval between the markers 2 is decided in advance, the running distance and the running speed of the running vehicle 3 can be detected with good accuracy.

Title: Control circuit of inverter for driving motor
Inventor: ISHII SHINICHI
IPC: H02P1/26
Filed: 1986-04-28
Abstract: PURPOSE:To prevent a voltage of an induction motor from abruptly varying at starting time by altering the proportional term of a voltage regulator at a predetermined change rate when starting the motor. CONSTITUTION:A deviation between a voltage command value input to voltage regulating means and actual voltage value is input to a multiplier 21. A proportional constant is fed to a soft starting integrator 23, and the output of the integrator is gradually varied at predetermined time change rate only at starting time. The result of the multiplication of a deviation between the voltage command value and the actual voltage value and a varying proportional constant by a multiplier 21 is input to an integrator 22 for a regulator. The output of the multiplier 21 is added to the output of the integrator 22, the voltage command value is further added thereto as the output signal of the voltage regulator. Thus, it can prevent a rush current from generating upon abrupt change of the voltage when a motor is started.

Abstract: PURPOSE: To reduce the generation of noxious components especially at a warming- up period and providing the improved engine braking, by varying according to the temperature of an engine, the dushpot effect of preventing a throttle valve inside a carburetor from being abruptly closed.  
     CONSTITUTION: A throttle valve 16 inside a carburetor 10 is linked to a diaphragm unit 18 for a dushpot by a lever 17 and a rod 24 which can freely contact with the lever. A chamber within the unit 18 is communicated with an atmosphere port 22 by a channel on the way of which a negative pressure delay valve 20 consisting of a check valve 20a and an orifice 20b is formed. The chamber is communicated with the atmosphere port 22 by another channel of a bypass passage 30 on the way of which are equipped thermostatic valve 34 and a restriction 36. The thermostatic valve 34 is closed at the warming-up of an engine performed when the temperature of a cooling water 32 stands under a specific temperature. In case the temperature exceeds the specific value, air is purged from both the passages so that the dushpot effect may be dampened.

Title: Sample hold circuit
Inventor: KASHIMOTO KOJI
IPC: G11C27/02
Filed: 1989-04-18
Abstract: PURPOSE:To suppress fluctuation in the charging voltage of a capacitor even when a sampling circuit is made inactive for a long time by adding a current source to cancel and leaked current of the capacitor when the sampling circuit is made inactive. CONSTITUTION:A current source IH is newly added to cancel the leaked current of a capacitor C1 when a sampling circuit A is made inactive. When the sampling circuit A is made inactive (when a control signal P is 'L',) any current is not supplied from a current source I0 to the capacitor C1 and the capacitor C1 is charged only by the current source IH. Since the current value of the current source IH is determined to be equal with the leaked current value of the capacitor C1, the charging voltage of the capacitor C1 is not fluctuated even in case the sampling circuit A is made inactive for a long time. As a result, the level of a signal to an output terminal 7 is not changed as well.
