Patent JP-H0916273-A (JP)
Title: Temperature control unit
Inventor: OGIWARA MOTONORI
IPC: G05B21/02
Filed: 1995-06-30
Abstract: PURPOSE: To obtain quick response and reduce discrete noises and aliasing noises by setting a proper thermal time constant for a temperature sensor and setting a control period to a control period shorter than the sampling period of a sampling temperature detector. CONSTITUTION: A temperature operation unit 3 receives operation information and feeds or absorbs heat to or from a controlled body 4 with a response time T1 and a temperature sensor 6 detects the temperature of the temperature operation unit 3 surrounded with a member which has a thermal time constant so as to reduce high frequency components of temperature variation. The sampling temperature detector 7 samples the output value from the temperature sensor 6 at a period T3 and outputs temperature information. A feedback information generator 8 generates feedback information at a period T0 obtained by equally dividing the temperature information by (n) according to the temperature information. A command sampling unit 1 samples command temperature at the period T0 and outputs command information.  A controller 2 outputs operation information at the period T0 according to the command information and feedback information. Then relations of T1<T0<T2<T3 and T0=T3/n are set.

Title: Hydraulic brake device
Inventor: NOMURA YOSHIHISA
IPC: B60T8/1761
Filed: 1987-07-28
Abstract: PURPOSE:To prevent the lowering of brake fluid pressure at the time of the failure of a second brake system by forming a cylinder bore into a stepped cylinder bore in which a small diameter part and a large diameter part are formed in front and in rear in a position between a pressurizing piston and an input piston and fitting a stepped piston in this part. CONSTITUTION:When a second brake system is in failure, if a brake pedal 98 is slightly stepped, a closing valve 104 is opened feeding a brake fluid pressure from an external fluid pressure source into a first power pressure chamber 52. However, since the brake fluid pressure is fed into the second brake system through a second connecting port 64 and a third power pressure chamber 56, the fluid pressure is leaked out without generating a fluid pressure in the pressure chamber 52. Hence, a pressurizing piston 18 and a stepped piston 44 are at rest. When the pedal 98 is further stepped in and as the advancing quantity of an input piston 94 reaches a defined value, the piston 94 is brought into contact with the stepped piston 44, closing the closing valve 104 to cut off the connection between the first power pressure chamber 52 and a second power pressure chamber 54. And, the stepped piston 44 is mechanically advanced increasing the fluid pressure P1 in the pressure chamber 52 while also increasing the fluid pressure in a pressurizing chamber 28.

Title: Ionization-type smoke sensor
Inventor: KIMURA TETSUO
IPC: G01N27/64
Filed: 1981-11-26
Abstract: PURPOSE:To sense the abnormality of a sensor and the density of smoke by turning a switching circuit ON according to the difference between the output voltage of a charging circuit conducting charge and discharge at a prescribed time constant and the output voltage of the sensor whose impedance is turned low. CONSTITUTION:Positive and negative powers are supplied from a receiver to an alarm line L1 and a common line L2, a capacitor (C)O is charged therewith through a diode D for preventing a reverse current, and based on the charged voltage of CO, a voltage is impressed between the internal electrode of an ionization-type smoke sensor 1 and the external electrode thereof. The output of the sensor is inputted in a low-impedance transformer 2 formed of FET. The output of the transformer 2 is given to the base of a transistor (TR)T1 via a Zener diode Z1. The emitter of T1 is connected to the contact of a resistor (R)1 and C1, and T1 is turned ON at a prescribed voltage to make T2 and T3 conduct operations of charge and discharge. Accordingly, the period of a pulse train appearing at both ends of a resistor R2 changes according to the output voltage of the sensor 1, and thus the abnormality of the sensor and the density of smoke can be sensed by monitoring or measuring the period.
