Title: Ventilator
Inventor: NAGANUMA TATSUYA
IPC: F24F7/08
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To ventilate while suppressing a drop in heating efficiency by providing a heat exchanger on a stack of a fireplace. SOLUTION: A ventilation device 2 is provided with a ventilation duct 8 which includes a stack 6 of a fireplace 4 inside, a fan 10, which distribute an open air in the ventilation duct 8 and a first opening 14 which guides the open air which has been distributed through the ventilation duct 8. Therefore, the open air is introduced into the ventilation duct 8 by way of a ventilating opening 18 provided on a wall 16 of a room 12. A heat exchanger 804 of the ventilation duct 8 which includes the stack 6 inside, is arranged to heat the open air with the exhaust heat from the fireplace 4 while the open air is being distributed. Then, the open air is exhausted from the first opening 14 into the room 12.  Since the open air is heated with the exhaust heat of the fireplace 4, this construction makes it possible to suppress a drop in heating efficiency dramatically compared with the mere introduction of the open air into the room 12.

Title: Telephone set circuit
Inventor: KARAKI MASATO
IPC: H04M1/58
Filed: 1989-03-10
Abstract: PURPOSE:To prevent the generation of noise sound from a receiver during call by attenuating a transmission signal prior to the input to an output circuit when the saturation or a state just before the saturation of the output circuit is detected. CONSTITUTION:The circuit is provided with a saturation detection circuit 100 detecting the saturation or the state just before the saturation of the output circuit and a transmission signal attenuation circuit 200. When the saturation detection circuit 100 detects the saturation or the state just before the saturation of the output, the transmission signal prior to the input to the output circuit is attenuated. Consequently, even when a large noise due to an installation work or the like is inputted to a transmitter and an excess transmission signal takes place, the transmission signal level fed to the output circuit is suppressed to a proper level by the attenuation circuit 200 when the output circuit reaches the saturation or the state just before the saturation by the transmission signal. Thus, the balance state of the side tone preventing circuit is maintained and the generation of noise is prevented.

IPC: F02D11/10
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To provide an electronically controlled throttle valve device enhancing vibration resistance by a simple constitution. SOLUTION: Through a fixing bolt 6, an actuator fixing base plate 7 is fixedly tightened to a flange part 1B of a main unit 1A, so as to support an actuator 2 to the main unit 1A. Further, between a peripheral surface of a protruded part 2C and an internal peripheral surface of a case part 1C of the main unit 1A receiving the protruded part 2C, an elastic unit 9 is interposed, in this way, a side of one end 2B of a body of the actuator is also supported to the main unit 1A. In this way, a cantilever structure as in the past can be formed in a center structure, so that though a constitution simple with a cost reduced, vibration resistance can be effectively improved.  By interposing the elastic unit 9, considering position accuracy or the like of the actuator 2, necessity for enhancing work accuracy is eliminated, apprehension such as worsening assembly workability and increasing a cost can be eliminated.

Title: Method for cutting optical fiber
Inventor: SEIKE TAKEO
IPC: C03B37/16
Filed: 1989-03-11
Abstract: PURPOSE:To cut an optical fiber square to have a specular surface by loading tension on the optical fiber by the slip gripping force of clamps having the specified slip gripping force and thereby cutting the fiber. CONSTITUTION:The optical fiber 2 exposed by removing the coating in the terminal part of the coated optical fiber 1 is gripped approximately horizontally in the air by a pair of the clamps 3 which can make slip gripping of the fiber with the specified slip gripping force. An initial score is given to the surface of the optical fiber 3 by applying a scoring blade 4 on the optical fiber 2 between the clamps 3 in the direction vertical thereto and thereafter, a flat pressing block 5 is pressed vertically to the side opposite to the initial score. The tension is then loaded on the optical fiber 2 by the slip gripping force of the clamps 3 and the fiber is thereby cut. The cutting of the optical fiber 2 square to the specular surface is enabled in this way and the connection loss is decreased in the field of the connection of the optical fiber 2, etc.

IPC: G03B7/10
Filed: 1990-03-09
Abstract: PURPOSE:To photograph a subject with an excellent aperture quantity even if the subject has a high-brightness part by adjusting a clip voltage in response to a stop control means. CONSTITUTION:A clip voltage control circuit 28 is connected to the output of a comparison control circuit 24 and includes a filter circuit 32 which converts a control signal into a DC voltage, a bias circuit 30, and an adder 34 which adds the outputs of the bias circuit 30 and filter circuit 32 and supplies the sum to a clip circuit 20 as the clip voltage. Then the clip circuit 20 does not fix the clip voltage for clipping the high-brightness part of a video signal at a 1st clip voltage, but varies it according to the aperture quantity of the stop 12. Consequently, even if the subject has the high-brightness part, the subject can be photographed with the excellent aperture quantity.

Filed: 1978-05-19
Abstract: PURPOSE: To prevent pressure loss due to leak of solenoid valves and enhance the precision of pressure automatic calibration, by providing a device to store the reference calibration value and an operator, and additionally attaching solenoid valves.  
     CONSTITUTION: Solenoid valves 2, 8 are energized by a calibration signal, and valve port F-D-C- B-pressure transmitter 3 are made to conduct, and an atmospheric pressure is transmitted to the transmitter 3, so that a signal corresponding to the reference pressure may be outputted. This output is fed into a device 5 to store the reference calibration value through a changeover device 4, and the difference from the theoretical output signal value is stored as the reference calibration value. Next, the valves 2, 8 are de-energized by a measuring signal, and measuring point H-valve port A-B-transmitter are made to conduct. At the same time, point H'- valve port E-D-C in the vicitnity of point H are also made to conduct. Therefore, since there is no pressure difference between the valve port A-C and the valve port B-C, leak does not occur, so that the pressure in a piping 1 may be transmitted to the transmitter 3 without pressure loss. This output is supplied into an operator 6 through the changeover device 4, and, adding the calibration value from the device 5, a correct measuring value is outputted. Thus, along with the effect to prevent pressure loss, high precision of measurements may be achieved.
