Title: Optical disk device
Inventor: KONO KAZUHIKO
IPC: G11B7/126
Filed: 1999-12-13
Abstract: PROBLEM TO BE SOLVED: To prevent an erroneous recording or an erroneous erasing on another information surface being different from the one being recorded in a recording operation in an optical disk having a plurality of layers of information surfaces. SOLUTION: A focus monitoring means 16 monitors the increase of a focus differential signal (or a reflection light amount monitoring means monitors the reduction of the reflection light amount, the movement of the layer of the information surface is detected during recording) so that a light intensity control means 4 reduces the intensity of a light beam to the degree of a reproduction intensity. When a signal is recorded over the plurality of layers of information surfaces, the light intensity is temporarily reduced to the degree of the reproduction intensity, a layer movement control means moves the layer which the focus of the light beam follows and, then, the light beam intensity is increased to be a recording intensity again.  Then erroneous recording or erroneous erasing is prevented when focus control is out of order owing to a disturbance vibration or the physical defect of a disk, etc., or when the signal is recorded over the plurality of layers of the information surfaces.

Title: Liquid level detecting probe
Inventor: SHIGEMOTO AKIHIKO
IPC: G01F23/26
Filed: 1998-12-11
Abstract: PROBLEM TO BE SOLVED: To keep the output to be a fixed value and correctly detect a liquid level by coating fixed length from the tip of a liquid level detecting probe with an insulating film so as to keep insulation after the probe penetrates through a film until it contacts with a sample liquid level. SOLUTION: At the moment when a liquid level detecting probe 2 contacts with a film 8, it the film 8 is conductive, the probe 2 and the film 8 are in a conductive state, and change due to the contact appears in the output of an electrostatic capacity detecting circuit. When the probe 2 pierces through the film 8, the change disappears, and it returns to a signal in the non-conductive state. When the probe 2 contacts with the liquid level, change due to the contact with liquid appears in the output of the detecting circuit, and contact with liquid can be detected by a liquid level circuit.  Even when an insulating film 22 is coated only on the way part of a metallic tube 21, after the probe 2 penetrates through the film, by contacting the film 22 with the film 8, it returns to the signal in the non-conductive state, and when the probe 2 contacts with liquid level, the output of the detecting circuit largely changes. In this way, insulation is kept up to contact with liquid, change of the detected signal at contacting with liquid becomes large, and hence it can be correctly detected.

Title: Car steering device
Inventor: OMURA HIROSHI
IPC: B62D137/00
Filed: 1992-12-10
Abstract: PURPOSE:To enhance the maneuvering stability by controlling the rear wheel steering angle using the yawrate. CONSTITUTION:When the rear wheel steering angle is to be controlled in accordance with the turning angle of a steering wheel, the actual yawrate sensed is used as parameter. Therein an actual yaw acceleration calculating means 31 calculates the actual yaw acceleration from the actual yawrate which is sensed by a yawrate sensor 28, and a presumed yawrate calculating means 32 calculates the presumed yawrate from the output of a wheel speed sensor 27, and a presumed yaw acceleration calculating means 34 calculates the presumed yaw acceleration from the fore-foregoing presumed yawrate and the foregoing presumed yawrate. An allowable value setting means 35 cumulatively adds the specified allowable value to the presumed yaw acceleration at each calculation of the actual yaw acceleration and sets the updated yaw acceleration allowable value. An actual yawrate restricting means 36 admits the use of the updated actual yawrate if the updated actual yaw acceleration lies within the actual yaw acceleration allowable value and prohibits the use if lies outside of the region. This ensures an enhanced maneuvering stability.

Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To eliminate projections and sharp parts of the outside so as to make possible safe joint by fixing levers inside a clamp main body, and pressingly fixing a pipe to be joined by lever operation of a setscrew penetrating through the center of the lever. SOLUTION: Levers 3 having presser parts 2 are fixed with fixing parts 4, inside this clamp main body 1 joining together two pipes at right angles. The presser part 2 is formed into an elliptical flat plane, integratedly constituted with the lever 3, and a setscrew 5 is penetrated through the center of the lever 3. By rotating the setscrew 5, the lever 3 is rotationally moved, and the presser part 2 on the extreme end is moved up and down. Namely, when the setscrew 5 is twisted in one direction, by threaded engagement with the threaded groove of the lever 3, the lever 3 is elevated, hence the presser part 2 is pressure- contacted with a steel pipe 7 fitted to the clamp main body, and the steel pipe 7 is firmly fixed to the clamp main body 1.  When the setscrew 5 is twisted in the other direction, the lever 3 is brought down, pressing of the presser part against the steel pipe 6 is removed, and fixing can be released. Consequently, the clamp can be safely used after installation, and the pipes can be firmly fixed to the clamp.
