Title: Azimuth sensor
Inventor: KUMAGAI TATSUYA
IPC: G01C19/72
Filed: 1991-12-17
Abstract: PURPOSE:To perform highly precise azimuth detection without any influence of an environment with a short start time. CONSTITUTION:The optical fiber loop of an optical system 1 composing a sensor part 10 is vertically stood, and the rotational speed of the earth on its axis when rotation is performed centering a gravity axis by the use of a turn table 2 is detected. The rotational speed of the earth omega is shown in the expression of omega=k.sin(theta+a)+omega0 when amplitude k, rotation angle of the turn table theta, phase (a) and offset value omega0 are shown. The phase (a) in the expression is in the north direction to the main axis of an azimuth sensor and a main axis azimuth is calculated from the phase (a) by means of a control part 20. Particularly, while the direction of a loop face is changed with the turn table 2 rotated, current applied to an optical system light source is cut off or in the case where a gyro is a phase modulation type, with a modulation signal cut off, the circuit noise of the control part 20 is detected for purpose of the finding of a reference voltage value of sensor output. Before the angular velocity of the earth is measured, drive current or a phase modulation signal is input and, with the change quantity from the above reference voltage value measured, the angular velocity is found.

Title: Sliding gate plate
Inventor: ITO KAZUO
IPC: B22D41/36
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To make it possible to lower sliding resistance and to maintain a service life by forming a lubricating film of thermal decomposition carbon on the sliding surface of a sliding gate plate used for a sliding nozzle device. SOLUTION: A sliding gate plate body 20 is arranged in a heat treating furnace 10 and the temp. in the furnace is set at 800 to 1700 deg.C. Gaseous hydrocarbon 16, such as gaseous propane and gaseous ethylene, and a carrier gas, such as hydrogen, are introduced into the furnace while the flow rate thereof is controlled by a flow meter 14 to allow the thermally cracked carbon to deposit on the sliding surface 20a of the sliding gate plate. The pressure in the heat treating furnace 10 is preferably reduced by a pressure reducing means. As a result, the sliding gate plate has a lubricating film of the thermal cracking carbon on its sliding surface 20a and, therefore, even if this surface receives heat, the easy dislodgment of the lubricating film does not arise and the small sliding resistance is maintained. The life is thus prolonged.

Title: Piezoelectric driving conveyer
Inventor: MISAKI MASATOKI
IPC: H02N2/00
Filed: 1994-12-08
Abstract: PURPOSE: To provide a piezoelectric driving conveyer having a high conveying speed further with a speed almost not fluctuating even by an aging of conveyed object weight, by using two or more vibration exciters formed of bimorph, and fixing the vibration exciter vertically provided to tilt to a base by providing a specific tilt angle with respect to a base plane. CONSTITUTION: When AC voltage is applied to a piezoelectric element 2, a vibration exciter 1 formed of bimorph structure generates a bending vibration according to extending/contracting the piezoelectric element 2. This bending vibration is generated by positively/reversely changing polarity of the AC voltage applied. The vibration exciter 1 is vertically provided to tilt at a 55 deg. to 75 deg. tilt angle relating to a plane of a base 6, and when the vibration exciter 1 and a connecting member 4 are non-linearly fixed, a vibration is caused obliquely upward in a conveyed object 5 by receiving a bending vibration of the vibration exciter 1. Consequently, pressing force is applied obliquely upward to a conveyed part 8, to instantaneously levitate it in the air, and by resetting at this moment the fine displaced conveyed object 5 to the original position, the conveyed part 8 can be conveyed.

IPC: G11B7/004
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To provide a recordable optical disk device capable of determining a non-recorded area within a short time. SOLUTION: A TOT signal (total signal) corresponding to the total quantity of reflected light is compared with a defect detecting level L1 by a comparator 26 to generate an output. An RFRP signal corresponding to the envelope of an RF signal obtained from the reflected light is compared with a non-recorded area detecting level L2 by a comparator 25 to generate an output B. After the output B is inverted by a NAND 32 to generate an output C, the output A and the output C are multiplied by an AND 33 to generate a non-recording detecting signal D. By eliminating a short pulse from this non-recording detecting signal D, a non-recorded area determining signal is generated and, based on this signal, determination is made as to whether an area being scanned by an optical spot is a recorded area or a non-recorded area.

Title: Preventing device for adhesion of cooked rice inside cooking vessel
Inventor: NAGASAWA TEIZO
IPC: A47J27/14
Filed: 1988-12-27
Abstract: PURPOSE:To make it easy to transfer cooked rice in a lump to the other vessel, by a method wherein the cooked rice is alternately turned clockwise and anticlockwise by an agitating plate as soon as rice is cooked. CONSTITUTION:After a cooking vessel 1 washes and cooks rice automatically, it is transported on rollers 2 by their rotation. It is stopped by a projecting rod 3 and then held by holding arms 4, 4a which are projected from both the sides, right and left. After that, an agitating plate 5 suspended from above is lowered into the cooking vessel 1 and is alternately turned clockwise and anticlockwise for about ten minutes. The cooked rice adhering inside the cooking vessel 1 is thus separated from the cooking vessel 1 and then transferred to the other vessel. Since the cooked rice is separated from the cooking vessel 1, it does not happen that a part of the cooked rice remains on a bottom 1a by adhesion.

Title: Deflection circuit
Inventor: SEKINE AKIHIKO
IPC: H04N3/27
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To prevent the destruction of a transistor switch and to eliminate the expensive transistor switch of high pressure by providing a diode connected between an aspect change-over switch and a constant voltage source. SOLUTION: The diode 7 connected between the transistor switch 6 as the aspect change-over switch and the constant voltage source 8 is provided and the transistor switch 6 is protected. Since voltage at both ends of the transistor switch 6 is lower than the constant voltage source 8 at normal time, the diode 7 is not turned on. When a trouble occurs in the element of a deflection circuit and voltage on both ends of the transistor switch 6 is raised the diode 7 is turned on and voltage at both ends of the transistor switch 6 is clipped by the voltage of the constant voltage source 8. When the unexpected trouble occurs in the element of the deflection circuit, voltage is protected from exceeding maximum rated voltage by using the transistor switch 6 of low pressure so as to prevent the destruction of the transistor switch 6.
