Title: Magnetic disk device
Inventor: SUKEGAWA TAKESHI
IPC: G11B21/10
Filed: 1991-10-04
Abstract: PURPOSE:To shorten an inspecting time in the shipping inspection of a servo system and to perform the shipping inspection at a low cost and with high reliability by providing a loop gain switching mechanism on a magnetic disk device. CONSTITUTION:When the magnetic disk device is operated at a normal track follow-up mode, a gain changeover switch 1 is connected with A by the instruction of an instruction interface 14a. The switch 1 is connected with B by the instruction of the interface 14a at the time of the shipping inspection of the servo system, and by multiplying K times a signal outputted from a servo controller 3 and inputting to a servo amplifier 4a, the loop gain of the servo system is increased. The constant K of a stability constant (K) 2 for this is decided by the degree to expect the stability of the device. The magnetic disk device is operated, the switch 1 is connected with B and read/write is operated at the track follow-up mode. Thus, the inspection time is shortened and the shipping inspection is performed at a low cost and with high accuracy.

Abstract: PURPOSE:To improve the cooling effect of the cooling device in the caption, by installing mutually different liquid level detectors at a plural number of positions in a coolant chamber surrounding a combustion chamber and, spraying coolant through a nozzle located near a liquid level detector which has detected a low liquid level, when only said level detector detects the level lower than the pre-determined level. CONSTITUTION:A plural number of coolant nozzles 34, 36 are provided in mutually separated several positions in the direction of the array of cylinders in the upper area of a coolant chamber 14 which surrounds combustion chambers 12 of an internal combustion engine 10, each of nozzles, 34, 36 being connected to a coolant pump 52 via a flow switching valve 42. Liquid level sensors 62, 64 are installed positions corresponding to the respective nozzles 34, 36, the output signal of each level sensor being input in a control device 60. When both of the sensors 62, 64 detect the levels lower than the pre-determined level, a coolant pump 50 is actuated and, at the same time, the flow switching valve 42 is so controlled as to be switched to make the nozzle on the side of detected lower liquid level spray coolant.

Title: Photoelectric semiconductor device
Inventor: KATSUMOTO SHINGO
IPC: H01L31/04
Filed: 1986-10-29
Abstract: PURPOSE:To obtain a device which can initiate a switching operation by means of photovoltaic force of a diode by irradiating a beam of light by a method wherein an operating point is changed by making use of the change in the current-voltage characteristic when a beam of light is irradiated on a tunnel junction diode or a reverse junction diode. CONSTITUTION:A transparent surface electrode 3, a diode part 5 containing a tunnel junction 4, a resistor layer 6, a substrate 7 and a reverse-side electrode 8 are piled up in succession as counted from the top. If an external voltage V is raised gradually from O(V) and is set to a voltage value of VO, an operating point becomes a in the diagram. If a beam of light 30 is irradiated from the upper part of a device by keeping the state as it is, the current-voltage characteristic of the device having the tunnel junction 4 is shifted to i=f'(VD) in the diagram due to the photovoltaic force. As a result, the operating point is shifted from a to b. The external voltage, however, remains constant at VD+VR=VO thanks to a voltage-stabilizing circuit. If the beam of light is cut off again in this state, the characteristic is returned to the original one, i.e. i=f(VD) and the operating point is shifted from b to c. That is to say, a photoelectric semiconductor device initiates its switching operation at ia ic by the irradiation of light.

Title: Scramble processing system
Inventor: ABE HIKARI
IPC: H04L7/00
Filed: 1984-12-06
Abstract: PURPOSE:To prevent the generation of malfunctions by setting an artificial random code for scramble processing so that no correlation is produced to two orthogonal polarized waves. CONSTITUTION:When both bipolar signals 100v and 100h are cut off, the inputs 102v and 102h of scramble circuits 4v and 4h are set to 0 or 1 continuously. Thus artificial random codes are outputted as they are from circuits 4v and 4h. The artificial random codes produced from code series generators 5v and 5h for V and H polarized waves are not equal to each other and have no correlation. Under such conditions, the modulated input signals 103v and 103h are not equal to each other by changing the state of the initial value input 108 of each of shift registers S1-S7 set by a reset code 107 and therefore shifting greatly the bit phase between two (m) series codes with a simple code generator.

Abstract: PURPOSE: To reliably connect chip part tapes to each other in a short time by providing two intermediate reels between a chip part reel and a rewind reel and driving the intermediate reels to rotate only when the chip part tape is to be rewound. CONSTITUTION: A jig 1 is placed between a rewind reel 2 and first and second intermediate reels 3, 4, and a rear end of a chip part tape 5a wound around a reel of the wind reel 2 is connected to a front end of a chip part tape 5a wound around a reel of the first or second intermediate reel 3, 4 via a connection tape. Only when the chip part supply tape 5a is to be rewound around the respective intermediate reels 3b, 4b, reversely winding motors 3a, 4a are driven to rotate. Thus rewinding of the chip part tape 5a already connected and reverse winding of the tape 5a to be connected next for taking out its rear end are simultaneously done, thereby shortening the time required for connection.

Abstract: PROBLEM TO BE SOLVED: To make the change characteristic of the pressure of a hydraulic fluid equal when the steering torque is increased and when it is decreased by operating the second spool and the first spool for communicating a liquid feed discharge chamber and a liquid discharge chamber and for communicating a liquid feed chamber and the liquid feed/discharge chamber. SOLUTION: As the steering torque is decreased, a liquid feed/discharge chamber 48 and a liquid feed chamber 51 are kept in a noncommunicative state, and a liquid discharge port 56 and a liquid discharge chamber 54 are opened or closed in response to the balance of the steering torque applied to the second spool 45 against the hydraulic reaction of the hydraulic liquid in a pressure regulating chamber 70 and the pressing force of a pressing pin. The liquid discharge port 56 and the liquid discharge chamber 54 are kept at the communicative state until the pressure of the hydraulic liquid in a reaction chamber 46 becomes the set pressure or below, and the pressure of the hydraulic liquid in a cylinder chamber is quickly decreased.  When the pressure of the hydraulic liquid in the reaction chamber 46 becomes the set pressure or below, the hydraulic reaction corresponding to the steering torque is generated in the pressure regulating chamber 70, the liquid discharge port 56 and the liquid discharge chamber 54 are made in a communicative state, and the decreasing rate of the pressure of the hydraulic liquid in the cylinder chamber is reduced.

Title: Method for locating breakage of shielding sheet and shielding sheet detectable of breakage
Inventor: ONO FUMIYOSHI
IPC: E02D33/00
Filed: 1995-10-05
Abstract: PROBLEM TO BE SOLVED: To form a shielding sheet excellent in workability, quality control and durability by composing the shielding sheet such that a breakage can be located according to the presence of a current flowing through the conductive layer or conductive line in each of a large number of sections. SOLUTION: The shielding sheet 6 is composed of a large number of shielding sheet units U1-U16 where a conductive layer or a conductive part (line) is formed for each of a large number of sections on an insulating sheet 2. Conductors E1, E2, E3, E4,... of respective unit U1-U16 are connected in parallel with a power supply and a selector detects the current flowing through the conductive line 4 of each unit U1-U16. When one sheet 2 is broken to open the line 4, no current flows between the conductors E and thereby a broken unit U can be detected. Since the breakage of sheet 2 can be located by detecting the current flow, manufacturing cost of measuring instrument can be reduced significantly. Furthermore, since the detecting part is built in the sheet 2, the detection electrode is not corroded by decoction and the durability is enhanced.
