Title: 4-space type electromagnet device
Inventor: MATSUSHITA HIDETOSHI
IPC: H01F7/16
Filed: 1981-10-29
Abstract: PURPOSE:To maintain the sensibility of a polar electrical magnet device, by a method wherein the magnetization of a permanent magnet and that of a coil are paralleled. CONSTITUTION:The magnetic flux X of permanent magnets 9 and 10 flows towards the longitudinal elements 3 and 4 and the horizontal elements 15 and 16 of yokes 11 and 12, the right and left elements 7 and 8 of an armature 5, and the right and left elements 3 and 4 of the yoke 1. The magnetic flux of a coil Y flows towards the horizontal element 6 and the left side element 7 of the armature 5, the horizontal element 15 and 16, the right side element 8 of the yoke 11 and 12. The magnetic flux of the coil also flows towards the left side element 7 of the armature 5, the left side element 3, the lower element 2, and the right element 4 of the yoke 3, and the right side element 8 of the armature 5. Thus, the magnetic fluxes X and Y of the two are duplicated when they flow in the same direction, and they repell each other when one flows in the different direction from another, so the armature 5 moves horizontally to the left, and the right side element 8 is sticked on the right side yoke 12. With this method, the attracting force of the coil 18 is prevented from attenuation, enabling the polar electrical magnet device sensitivity to be maintained.

Abstract: PURPOSE:To promote sealing performance by filling a liquid sealing material into a recessed section of a channel in the shape of a trench in the vicinity of a side wall and inserting the lower end of a skirt member adhered and fixed to an extension section of a filter frame and the side wall to the inside of the sealing material. CONSTITUTION:Liquid sealing material 6 is filled into a recessed section of a trench shaped channel 1 placed in the vicinity of a side wall 9 in a ceiling frame hung from the ceiling, and an extension 8a of a filter frame 8 is inserted to the inside of the sealing material 6. A skirt member 10 is adhered and fixed to the side wall 9, and the lower end section 13 of the skirt member 10 is inserted to the inside of the sealing material 6 of the channel 1. According to the constitution, even if the channel 1 moves due to a certain factor, the lower end section 13 of the skirt member 10 moves the inside of the sealing material in accordance with it, so that an air leakage does not happen even though pressure is given to a calking material 15 to produce a crack.

Title: Polygonal mirror and laser printer
Inventor: SHIMIZU SEISABURO
IPC: G02B26/12
Filed: 1990-07-03
Abstract: PURPOSE:To prevent the flatness of a reflection face from being reduced due to the molding trail of an end face and to improve the flatness of a product and its productivity by surrounding the primary side face of preworking body by a resin molding layer and forming a reflection face forming metallic film on the resin molding layer. CONSTITUTION:The resin molding layer 26 is arranged so as to surround the primary side face 24 of the preworking body 12. The layer 26 covers the whole working body 12 except a shaft part 14 formed on the lower side of the working body 12 and an annular projection part 16 formed around the shaft part 14. The layer 26 is molded from resin having high fluidity and thermoplasticity by means of a metal mold. A metallic film 32 is formed on the supporting body coated with the layer 26 by evaporation, plating or sputtering. The film 32 covers the whole periphery of a secondary side face 28 to form the reflection face 34 of the polygonal mirror. Thereby, the secondary side face of the layer 26 becomes the intermediate part of resin fluid at the time of molding, so that resin trail is not generated and the flatness of the secondary side face of the layer 26 can be furthermore improved. Since the layer 26 surrounds the preworking body, the layer 26 can be prevented from being peeled off due to rapid rotation.

Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To discriminate a fault part, to facilitate maintenance and to monitor a transmission line during communication by providing a carrier monitor timer circuit which does not output a signal when a signal source breaks down but outputs the signal only when the transmission line breaks down. SOLUTION: A transmission monitor timer 15 for inhibiting continuous transmission for more than prescribed trainsmission time (t) is provided on a transmission-side 100. The carrier monitor timer circuit 16 for outputting the signal 17 when a reception carrier continuous for more than setting time (t) is provided for a reception-side. When a fault occurs in the transmission-side or an optical fiber 8, the light reception quantity of a receiver 9 reduces and an output signal 10 becomes unstable. the signal 17 is outputted when continuous time becomes setting time (t), the output signal 19 of a storage circuit 18 is kept, a lamp 22 is lighted, and reduction is displayed even if a carrier detection circuit 11 erroerneously recognizes the presence of the carrier and outputs a signal 12. A post-stage circuit stops the processing of the output signal 14. Then, setting time (t) is set to be considerably short and the transmission line can continuously be monitored even in regular communication.
Patent JP-H0462962-A (JP)
Title: Semiconductor device
Inventor: OKANE KENJI
IPC: H01L25/04
Filed: 1990-07-02
Abstract: PURPOSE:To propagate a signal at high speed and to reduce the power consumption and the board area of a semiconductor element by a method wherein an input/output buffer is inserted in a bus-line pattern. CONSTITUTION:An input/output buffer 7 is inserted in a bus-line pattern 6b; semiconductor elements 18 are not provided with any input/output buffer. An electric signal which is taken out to the outside of a substrate 1 out of electric signals which are propagated on a branch wiring pattern 6a and the bus-line pattern 6b is current-amplified by the buffer 7 inserted in the pattern 6b just before a wiring pad 5 and is propagated to the outside via an input/output terminal 3. Since input/output pads inside elements of the individual semiconductor elements 18 are not provided with any input/output buffer, the signal is propagated at high speed. Since an inessentially large current driving capacity is not given to a signal closed inside the substrate 1, the power consumption of the elements 18 can be reduced. Since the buffer 7 is inserted, it is not required to newly mount a semiconductor element for drive use and a substrate area can be reduced.

Filed: 1989-07-05
Abstract: PURPOSE:To prevent the deterioration of the changing process response by registering the data retrieved by a reading means into an area prepared by an area securing means and changing en block the large quantity of data. CONSTITUTION:When a process start instruction received from a starting program 1, an area securing means 2 secures a retrieved data store area 9.

Then a registering means 5 registers the data coincident with the changing conditions into the area 9. A changing means 6 is started when all data are retrieved and the changing processes are carried out en bloc according to the change information. Thus it is possible to minimize the number of times of the input/output caused by the changing processes of a large quantity of data and to prevent the deterioration of response due to the input/output operations.

IPC: G11B5/09
Filed: 1990-07-03
Abstract: PURPOSE:To simultaneously decide an allowance degree of the amplitude detection and that of the discrimination of a phase by overlapping noise in an appropriate size on a read signal. CONSTITUTION:An attenuation circuit 11 is incorporated and it is operated when the insurance test of a read operation is conducted. A servo signal is attenuated to the voltage of appropriate amplitude and it is overlapped on the read signal 101. Thus, the allowance degree of the detection of amplitude and the allowance degree of the discrimination of the phase can simultaneously be decided. Since a threshold voltage switching control circuit for conducting the test of the allowance degree of the amplitude detection and a delay quantity switching control circuit for conducting the test on the allowance degree of the discrimination of the phase become unnecessary, the control circuit can be simplified, the reliability of a whole system can be improved and the insurance test can be simplified.
