Filed: 1985-09-18
Abstract: PURPOSE:To irradiate a high output laser beam to one point by making a light emitting element of each light source of a light source array coincide with the focal position of each collimating lens of a collimating lens array. CONSTITUTION:From each semiconductor laser 2... of a semiconductor laser array 1, divergent laser beams L... are emitted, and led to a collimating lens array 3. This array 3 is constituted by arranging plural pieces of collimating lenses 4... such as spherical lenses, etc., and a light emitting point of each semiconductor laser 2... of the semiconductor laser array 1 is made to coincide with a focal position of said each lens 4.... Accordingly, the divergent laser beams L... which are led to this collimating lens array 3 are converted to a parallel luminous flux whose section is elliptical by passing through the collimating lens array 3, and thereafter, led to a refracting prism 5 being a beam shape converting means, and converted to a parallel luminous flux whose sectional shape is corrected, by passing through this refracting prism 5. In such a way, even if plural light emitting points exist, the laser beams L... can be condensed to one point by one piece of lens 6.

Abstract: PURPOSE: To obtain a synchronizer in which instability for synchronizing a digital signal by AC is avoided by providing a first counter for generating a total count, second counter for conducting second count sequence and a latched circuit. CONSTITUTION: A first counter 34 responds to a preset line pulse on a line 36 to preset and start first count sequence at a predetermined phase point. A latched circuit 44 is useful as dividing means for receiving only a bit from a selected upper part 48 of the counter 34 and dividing clock value by a selected integer '1'. Further, a second counter 54 sends to a decoder 66 via a bus 64. The decoder 66 senses the time when complete countdown to '1' is performed, and generates an achievement signal on a line 68. If next line pulse arrives at a line 56, the counter 54 is reset, and continued counted number is received by the but 52 from the latch 44.

Title: Controller for stepping motor
Inventor: NAGAI KAZUNOBU
IPC: H02P8/00
Filed: 1991-08-19
Abstract: PURPOSE:To suppress rotational fluctuation by operating an auxiliary switching element in non-saturated region when the reduction rate of current command value for motor winding, defined by a current command signal, exceeds a set value. CONSTITUTION:An operating means 24 operates reduction rate of current command value for motor windings 2, 3 based on a current command signal. When the current command value decreases abruptly and the reduction rate exceeds a set value, operation control means 21, 25 control auxiliary switching elements 8, 9 to operate in non-saturated region based on the operation content of the operating means 24. Consequently, impedances of the auxiliary switching elements 8, 9 increase and the electrical time constants of the motor windings 2, 3 decrease equivalently during an interval when a circulation current flows through the auxiliary switching elements 8, 9, resulting in suppression of rotational fluctuation.

Title: Degenerate trouble detection circuit for logic circuit lsi
Inventor: SUENAGA FUMIHIRO
IPC: G01R31/317
Filed: 1989-08-11
Abstract: PURPOSE:To enable the detection of a degenerate trouble without a specific test pattern by a method wherein an input, an output, and a detection switch are controlled through a first external pin, the logic concerned is designated through a second external pin, and the logic '1' or '0' is read out through a third external pin and discriminated. CONSTITUTION:An input switch 13, an output switch 14, and a detection switch 18 are controlled through a first external switch 19-1 of a logic LSI 10 through the intermediary of a control line (single dotted chain line). The logic '1' or '0' is assigned for a logic generation section 15 through a second external pin 19-2 through the intermediary of a control line (double dotted chain line). The assigned logic '1' or '0' appearing in the output of a discrimination gate 17 is read out through a third external pin 19-3 to discriminate if a degenerate trouble occurs or not. If the logic generation section 15 outputs the logic '1' and the output of the external pin 19-3 is fixed at '0', it is clear that a '0' degenerate trouble occurs, and if the logic generation section 15 outputs the logic '0' and the output of the external pin 19-3 is fixed at '1', it indicates that a '1' degenerate trouble occurs. By this setup, the detection of a degenerate trouble can be executed without a conventional logic function check test pattern.

Title: Erasable programmable read-only memory
Inventor: TSUJI KAZUTO
IPC: G11C16/18
Filed: 1985-09-19
Abstract: PURPOSE:To readily manufacture an erasable programmable read-only memory by forming the lower surface of a light transmitting plate in a concave-curved surface to avoid the contact of the plate with connecting wirings even if the center is displaced. CONSTITUTION:A light transmitting plate 7 is contracted longitudinally and laterally, and the surface 7a is formed in a spherical concave-curved surface. The plate 7 is used in combination with a semiconductor chip 1 formed with bonding pads 1b on four sides. Since an interval from the periphery of the plate 7 to connecting wirings 3 is large at this time, it can be readily associated. Since the plate 7 can disperse an incident light L after passing the surface 7a, the size (c) of the plate 7 may be smaller than the size (a) of a memory cell 1a, and even if both are slightly displaced at the centers, the light L can be projected to the entire cell 1a.

During the decompression, the coolant is evaporated, and the oil is cooled by its heat of vaporization, and then, the cooled oil is mixed in the intake hole 5 without receiving incoming heat from the surroundings as the throttling part 25 is arranged near the intake port 5. The oil mixed in the intake port 5 enters an intake chamber and moves to a compression chamber together with a roller 13. A part of the oil enters a sliding part between a roller 13 and a vane, and forms an oil film.

Title: Magnetic head and manufacture thereof
Inventor: MUKAIDE NORIAKI
IPC: G11B5/187
Filed: 1991-08-20
Abstract: PURPOSE:To prevent the generation of an adjacent crosstalk by arranging a metal magnetic film exposed to a medium sliding surface that a nearby part extending from a magnetic gap is made parallel along the direction of the medium at the same angle as an azimuth. CONSTITUTION:A pair of cores 21 comprising a non-magnetic body is joined integral through a metal magnetic film 24 with high saturation flux density between joint surfaces thereof and a magnetic gap (g) with a specified azimuth is formed on a medium sliding surface of a core chip 22. The metal magnetic film 24 exposed to the medium sliding surface 23 is so arranged that a nearby part (m) extending from a magnetic gap (g) is made parallel along the direction in which the medium runs at the same angle as the azimuth. As a result, when information with the magnetic gap is read out, the metal magnetic film 24 will not be positioned with a recording track adjacent to a recording track from which a reading is performed into the medium. This eliminates the generation of an adjacent crosstalk, which otherwise will cause a reading of information from the adjacent recording track and thus, there is no generation of undesired noise in the reproduction.

Title: Testing method of heat resistant spalling for electrically non conductive refractory
Inventor: TANAKA SEIJIROU
IPC: G01N3/60
Filed: 1983-11-04
Abstract: PURPOSE:To enable relative evaluation of the heat resistant spalling property of non-electrically conductive refractory by providing an electric conductor adjacent to a non-electrically conductive refractory sample to perform a high frequency induction heating. CONSTITUTION:A specified high frequency output is applied to an electric conductor 1 as heating medium set adjacent to an non-electrically conductive refractory 2 from a high frequency coil 3. With the application of a specified high frequency output to the high requency coil 3, the electric conductor 1 causes a secondary induction current thereinside and generates heat sharply by the Joule heat generation thereof. Then, the heat transmits to the adjacent non-electrically conductive refractory sample 2 to develop a temperature gradient therein, ultimately causing a cracking accompanied by the generation of a thermal stress. Thus, depending on the difference in the condition with and without cracking, the propriety of the heat resistant spalling property can be evaluated.
