Title: Disc motor controller
Inventor: NAKANE HIROSHI
IPC: G11B25/04
Filed: 1994-08-31
Abstract: PURPOSE: To obtain a disc motor controller in which the time to be elapsed before the relative speed between a disc and a head is settled after a track jump can be controlled by differentiating the torque being generated from a disc motor at the time of acceleration and deceleration. CONSTITUTION: Based on a motor drive signal received from a power amplifier 17, a level detection circuit 20 delivers a voltage level corresponding to the level of a current flowing through a disc motor 12 to a level comparison circuit 21. A reference level generation circuit 23 determines whether the motor 12 is accelerated or decelerated through a torque direction decision circuit 22 and delivers a first or second reference level selectively to the circuit 21 based on a decision signal. The circuit 21 compares the outputs from the circuits 20 and 23 each other and delivers a torque limit signal corresponding to the level difference to a current limit circuit 24. The difference between the output voltage level from the circuit 20 and the first reference level is set lower than the difference between the output voltage level from the circuit 20 and the second reference level.

Title: Scramble method in pay television system
Inventor: HOSOYA NOBUKAZU
IPC: G06F21/10
Filed: 1983-11-04
Abstract: PURPOSE:To accelerate a subscriber's poling speed by encoding reserved information and channel information and by inserting it within a period of blanking. CONSTITUTION:Terminals 1 and 2 are inputted by input and output trminals and scramble data are inputted from a terminal 27. By scrambling a signal within the blanking period during television signaling by an integral-fold pulse of horizontal frequency in order to allow the signal not to descramble, the method is devised to prevent deterioration of a printed image. Furthermore, reserved information and channel information are encoded by a code which is correlated with said pulse and inserted into a blanking period, which allows obtaining only data whose program is selected, thereby permitting acceleration of each subscriber's poling speed.

Title: One-way clutch unit
Inventor: HORI SEIJI
IPC: F16D41/06
Filed: 1993-07-30
Abstract: PURPOSE:To reduce the extent of manhours for assembling by installing a hollow shaft integrally in the inner diametral part of a rotational transmission member in one side of both input and output sides, having a one-way clutch, using it as an inner ring, built-in another rotational transmission member, and installing a sliding bearing surface in a spot undone from each hollow shaft of both these rotational transmission members. CONSTITUTION:An input gear 1 forms an inner diametral surface into a stepped cylindrical surface, and a hollow shaft 5 is integrally secured to the large diametral part. This hollow shaft 5 serves as an inner ring of a one-way clutch 3 which is housed in an annular recess of an inner circumference of an output gear 2, whereby it is prevented from slippting off by a ringlike cover member 6. An inner diametral surface of the output gear 2 is formed into a stepped cylindrical surface, an intermediate diametral part 2b is somewhat larger in diameter than an outer diameter of the hollow shaft 5. Rotation of the input gear 1 is transmitted, one direction alone, to the output gear 2 via the one-way clutch 3. Both these gears 1 and 2 are supported by two sliding bearing surfaces 1a and 2a consisting of each inner diametral surface of these gears 1, 2 themselves on a fixed shaft 4. Therefore another sliding leering falls into disuse, through which the number of part items is reduced, and manhours for assembling is also reduced, so that manufacturing cost can be cut down yet cheap.

Title: Substrate for contact type linear sensor
Inventor: SAITO TAKASHI
IPC: H04N1/028
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To increase flexibility in a sensor fixing position and pattern arrangement by forming a floating pattern at a sensor fixing part except for the pattern of a substrate for adhering a sensor thereto so as to stably fix a sensor chip. SOLUTION: A floating pattern (abandoning pattern) 2d is formed at a part having no pattern on the lower surface of a sensor chip. The pattern 2d is used for the fixed pedestal of the sensor chip and is not connected to any part electrically. In this case, the pattern is simultaneously formed with a wiring pattern at a part which is wider than the sensor chip and is not arranged with a wiring pattern where the sensor chip is extended across. By simultaneously forming with the wiring pattern, is can be used as the pedestal of the sensor chip without increasing a manufacturing cost, the sensor chip can stably be fixed. Further, restriction is eliminated in the arrangement of he sensor chip and the criteria of the fixing position of the sensor chip is made.

Title: Surface grinding device
Inventor: IKEMOTO KIYOSHI
IPC: B24B37/28
Filed: 1997-07-17
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of rolling-off by setting a gear ratio among a carrier, a solar gear and an inner gear to a specified ratio. SOLUTION: A gear ratio among a carrier 14, a sun gear 12, and an inner gear 13 is set to 1:3:5. In other words, if the radius of the carrier 14 is (r), the radius of the sun gear 12 is 3r, and the radius of the inner gear 13 is 5r. Thus, the inner and outer peripheral radiuses of surface plates 10 and 11 approximately become 3r and 5r, and a part of about 2/5 of the outer peripheral side of the surface plate having the radius 5r is used as a work surface for grinding. This means that a surface plate is large and the ratio of the width H of the work surface with respect to the surface diameter is small, and thus a difference in circumferential speeds between the inner and outer peripheral sides of the surface plates 10 and 11 is greatly reduced. Therefore, the occurrence of rolling- off caused by such circumferential speed difference is prevented.

Abstract: PURPOSE:To attain logical verification by making a signal type coincident with each other between signals whose signal type differs through the use of a type conversion function in the system describing the hardware of a logic circuit comprising components having plural signal types. CONSTITUTION:A conversion graph generating section 31 reads signal type data to generate a conversion graph. A signal collation section 32 extracts a component, checks a signal type defined in the inside of the component and extracts a signal type of an input signal and an output signal to/from the component.
