Title: Bone conduction microphone
Inventor: OKI YUKA
IPC: H04R1/00
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a bone conduction microphone capable of preventing noise generated due to the attachment/detachment of a bone conduction microphone body or the like from being outputted to other equipments without deteriorating the sensitivity of voice oscillation detection. SOLUTION: The bone conduction microphone is provided with a voice oscillation detection part 5 for detecting and converting voice oscillation propagated through bones into an electric signal, an amplifier 6 for outputting the output of the detection part 5 to other equipments, a gain control part 11 for controlling the amplification factor of the amplifier 6, and a drive signal preparing part 30 for driving the control part 11. At the time of detecting that voice oscillation detected by the detection part 5 includes much noise, the gain control part 11 reduces the amplification factor of the amplifier 6 or completely reduces the factor up to '0' so that a signal including many noise components is not outputted from the amplifier 6 to other equipments.

Title: Fuel feeder
Inventor: OOYAMA TAKASHIGE
IPC: F02D45/00
Filed: 1978-06-28
Abstract: PURPOSE:To prevent the wrong distribution of fuel and the fall in the output of an engine, by setting the degree of opening of a second throttle valve through a diaphragm which is actuated depending on the average of the negative pressure in a venturi part at the upstream side of a first throttle valve and the positive pressure at the upstream side of the second throttle valve. CONSTITUTION:Negative pressure necessary to actuate the diaphragm 27 is synthesized in a passage connected to a first negative pressure outlet port 32 provided in the narrowest section of the venturi part 23 and to a second negative pressure outlet port 33 provided at the upstream side of a throttle valve 2'. In the slow rotation of the engine with a small quantity of supplied air, only another throttle valve 2 is opened and the speed of flow through the nozzle port 11 of an injector 4 is kept high because the negative pressure in the negative pressure outlet port 32 is too low to actuate the diaphragm 27. As a result, the atomization of fuel is accelerated and the wrong distribution of fuel and the fall in the output of the engine are prevented.

Abstract: PROBLEM TO BE SOLVED: To obtain an image pickup optical system which can enlarge and record a photographed image on an imager and a silver salt film although the size is small by providing the fiber optical plate(FOP) which operates for enlargement. SOLUTION: The FOP 103 has a different in size between its incidence end surface and projection end surface and has, for example, ×2 enlarging power. The FOP 103 is so arranged that the formation position of a 1st intermediate image 102 formed by an image pickup lens 101 meets the position of the incidence end surface of the FOP 103. A 2nd intermediate image 104 is formed on the projection end surface of the FOP 103. The image receiving surface of the imager 105 is arranged in contact with the projection end surface of the FOP 103. Or the imager 105 and FOP 103 are integrated. The image picked up by the image pickup lens 101 is enlarged double by the FOP 103, so the image pickup lens 101 can be made small-sized.

Title: Waveguide type electro-optical element
Inventor: SONODA SHINICHIRO
IPC: G02F1/295
Filed: 1994-04-15
Abstract: PURPOSE:To decrease DC drifts even if input light is short in wavelength or high in intensity by forming buffer layers of a material having a dielectric constant. CONSTITUTION:Resist patterns of EOG electrodes are formed by photolithography on an optical waveguide 11 and thereafter the film of HfO2 is formed as the buffer layers 12 on these electrode patterns. Al which is an electrode material is deposited by evaporation thereon and the resist is lifted off, by which EOG electrodes 13 are obtd. In such a case, the buffer layers 12 which are separated by each of the respective electrode parts are formed. The material having the dielectric constant 20 to 200 is preferably formed in terms of ease of film formation. Since the dielectric constant of the buffer layer material is large, the capacitance thereof increases. A change in effective voltage, i.e., the DC lift is suppressed exclusive of the case the resistance of the optical waveguide 11 is larger than the resistance of the buffer layers 12.

When the sheet 5 is held down with the pressing leg parts 9 and a higher elongation than that of the sheet 5 extending within the range of service temperature of the greenhouse is preliminory applied, the strength for pressing the sheet 5 with both ends of the pressing legs 9 in the longitudinal direction is reduced as compared with that in the case where the tilted parts (9a) is not installed. Thereby, the sheet 5 is not damaged.
