Abstract: PURPOSE:To stabilize the operating action of a burst control oscillator by using a circuit element produced with addition of a digital signal processing function to form the oscillator which extracts the clock signal corresponding to a prescribed subcarrier frequency out of a burst signal contained in a video signal. CONSTITUTION:A voltage control oscillator 11 has its transmission frequency which is controlled in response to the input of an analog phase difference signal and produces a clock signal of a frequency four times as much as the subcarrier frequency of a burst signal to output it through a terminal 35 and also to send it to a frequency counter 12. The counter 12 divides the received clock signal down to the 1/2 and 1/4 frequencies, and the former clock signal is sent to an A/D converter 1 as well as to registers 2 and 7. While the latter clock signal is outputted through a terminal 54 and also sent to a selector 5. Thus the clock signal corresponding to the subcarrier frequency of the burst signal received via a terminal 51 and forming a digital phase control system is outputted from the oscillator 11. Then the operating action of the oscillator 11 is stabilized.

Title: Semiconductor pressure sensor
Inventor: HIDA TOMOYUKI
IPC: G01L9/00
Filed: 1989-12-22
Abstract: PURPOSE:To obtain the small-sized, high-performance sensor by arranging a hermetic seal terminal for sending out the electric signal of a heat sensing element, an electric conductor for sensor temperature compensation, and an element on a pedestal except in a semiconductor single crystal substrate mounted area. CONSTITUTION:A pressure sensing element 1 is mounted on the pedestal 2, which is expanded in area more than a semiconductor single crystal substrate 10; and the hermetic seal terminal, electric conductor for the temperature compensation of the sensor, and element (resistance, thermistor, etc.) are arranged in the expanded area. Consequently, the pedestal 2 has a function for mounting the pressure sensing element 1 and also functions a base with the hermetic terminal 5 and the electric conductor plate which are prepared separately so far. Consequently, the number of components of the sensor is decreased to reduce the size of the sensor. Then the structure is rationalized and airtight connection parts between components are reduced to improve the assembly performance. Further, when the pressure sensing element is mounted and joined on the pedestal, a joining layer is extremely thin and the pedestal is made equal or close in coefficient of linear expansion to the semiconductor single crystal substrate which becomes the pressure sensing element to maintain the airtightness of the sensor.

Title: Foodstuff pulverizing device
Inventor: YANAGIDAIRA CHUKEI
IPC: B02C18/08
Filed: 1993-12-28
Abstract: PURPOSE:To improve the product yield and reduce cost by forming a ventilating hole for air vent which penetraes through an annular partitioning wall whose diameter is reduced towards the bottom part. CONSTITUTION:When a container body 43 is gradually tilted to drain water, and the water level lowers, a gap having the lower pressure than the atmospheric pressure is generated at the part surrounded between the outer peripheral surface of an annular partitioning wall 41, inner peripheral surface of the container body 43 and the water surface. Since a ventilating hole 42 which penetrates through the obverse and reverse surfaces is formed, midway on the cylinder partitioning wall of the annular partitioning wall 41, the outside air is gently introduced into the gap which has the low pressure and is formed between the annular partitioning wall 41 and the container body 43 through the ventilating hole 42, without agitating and mixing the objective substance to be pulverized, and the discharge of the pulverized substance together with water is suppressed, and the product yield is improved. Further, even if an accommodation container 40 is tilted in the horizontal direction, and water is continuously discharged from one end, the pulverized substance intrudes into the part between the outer peripheral surface of the annular partitioning wall 41 and the inner peripheral surface of the container body 43, and the quantity of the flow-out of the pulverized substance together with water is reduced, and the product yield is increased, and the production cost is reduced.

Title: Rotary damper
Inventor: TAKAHASHI KENJI
IPC: F16F9/14
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To reduce rotational torque caused by friction between an O ring and non-rotational member by dispensing with a large diameter flange to be provided at a rorary member, and performing prevention of leakage of viscous fluid around the rotary member at a position around an extension part whose diameter is smaller than that of a shaft part. SOLUTION: A seal member 12 on a rotary member 16 sealing visous fluid in a chamber 11 is attached onto an extending part whose diameter is smaller than that of a shaft part 17. With the constitution, the contact area of the member 12 with an inner diameter part of an end cover 13 is made small, thereby minimizing the influence of frictional force generating thereat on the rotational torque of the member 16. Since there is no large diameter flange part defining an axial end of the chamber 11 in the member 16, even if high pressure causing a large damping action in the chamber 11 of a housing 10 is generated, no thrust force acts on the member 16, thereby generating no friction between the member 16 and the cover 13 of the housing 10.

Abstract: PURPOSE:To execute an optimum temperature control even if thickness of a form changes by controlling a temperature by correcting a temperature control reference of a heat fixing part, based on heat conduction information of the form, in a printing state of an electrophotography system. CONSTITUTION:A heating element temperature control part 1 controls a heating element 2 so as to become a prescribed temperature. A form detecting element 3 such as a thermistor, etc., is placed so as to be opposed to the heating element 2, and detects a temperature of a form 4. A heat fixing roller 6 is heated by a control output of a heat fixing part temperature control circuit 5, and feeds out the form 4, while rotating. A heat fixing roller temperature detecting element 7 comes into slide-contact with the roller 6 and detects a temperature, and brings it to feedback to the control circuit 5. In this constitution, a temperature of the element 3 is compared with a reference value and held until the form 4 passes through the roller 6. By comparing a detection signal of the element 7, based on this difference signal as a reference, a temperature of the roller 6 is controlled. In such a way, even if the form changes, a temperature of the roller 6 for fixing a toner is held automatically at an optimum temperature.
