Title: Ultrasonic motor
Inventor: MUNEISHI TAKESHI
IPC: H02N2/00
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To greatly reduce a fluctuation in frictional force caused by an uneven contact, by forming the contact surface of an upper friction member into a projecting shape. SOLUTION: The ultrasonic motor 1 comprises a vibrating body 2 formed out of a piezoelectric element 4, and a rectangular parallelepiped friction member 3 which is fastened to the end surface of the vibrating body 2 and draws an elliptic track according to the vibration of the vibrating body 2, and has a front end surface, that is, a contact surface 3a coming into contact with a body to be driven. The contact surface 3a of the friction member 3 is formed into a curved and projecting shape, and positioned so as to be pressed against the side surface of the body to be driven. When AC voltage is applied to the ultrasonic motor 1, the friction member 3 draws an elliptic track according to the vibration of the vibrating body 2, and moves the body to be driven by friction force developed between the body to be driven and it at that time.  The friction member 3 comes into contact with the body to be driven in the center of the contact surface 3a, so that it comes into contact therewith so as to be roughly symmetric with respect to the minor axis of the elliptic track even in case that an uneven contact occurs. It is thus possible to greatly reduce fluctuation in frictional force caused by an uneven contact with the body to be driven.

Title: Magneto-optic disk apparatus
Inventor: SHINKAI HIROKO
IPC: G11B33/14
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To prevent clogging of a filter and eliminate exchanging of the filter, by mounting cooling/cleaning filters at two points of magneto-optic disk apparatus and reversing a feeding direction of wind by a fan. SOLUTION: A first filter 7a and a second filter 7b are set at a rear face and a side face of the magneto-optic disc apparatus. The air purified by the filter 7b cools a part of a magneto-optic disk easy to generate heat, and is discharged to the filter 7a. If the filter 7b is used as it is, dust of the outside air adheres to the filter 7b and clogs the filter 7b. Therefore, a fan is regularly reversed to guide the air flow from the filter 7a to a direction 8b and discharged to the filter 7b. Accordingly, the dust adhering to the outside of the filter 7b is removed and the air sufficient to cool is fed to the disk.

Title: Air conditioner for automobile
Inventor: HAYASHIBARA MITSUO
IPC: B60R16/04
Filed: 1988-11-07
Abstract: PURPOSE:To make it possible to store things possibly to be damaged due to the rise of temperature safely in an automobile by making a thermoelectric element to operate to cool the inside of a box when the temperature inside the box rises by a thermostat, which allows flow of electric current when the temperature comes to be a specific value. CONSTITUTION:A solar battery 11 with a light reception area of 900m<2> is mounted on the sunroof of an automobile 7, and when the solar battery 11 and a thermoelectric element 10 are connected together, the solar battery 11 generates electric energy of about 10W during the day of midsummer. And a temperature inside the automobile is detected by a thermostat 4. Next, if the temperature level of the thermostat 4 is set at about 25 deg.C, when the temperature exceeds 25 deg.C, electricity is sent from the solar battery 11 to the thermoelectric element 10 and the output of the solar battery 11 is supplied to the thermoelectric element 10. Consequently, the inside of a box 8 is cooled down. If bismuth-tellurium of about 50X50X3mm size is used as the thermoelectric element 10, the cooling of about 20W is possible and even if the solar light shines directly on the two faces of the box 8, the heating value is about 8W and it can be thoroughly cooled down with the thermoelectric element 10.

Title: Production of methacrylic resin
Inventor: MAEDA KATSUAKI
IPC: C08F6/00
Filed: 1985-12-13
Abstract: PURPOSE:To obtain a methacrylic resin low in a volatile component content, free of coloration and high in an optical purity, by adding a phosphorus ester compound to a methacrylic polymer composition containing a large amount of a volatile component and devolatilizing it by casting with heating. CONSTITUTION:A methacrylic polymer composition containing a large amount of volatile components such as unreacted monomer, a solvent and by-products of polymerization is mixed with 0.01-0.50pt.wt. phosphorous acid per 100pts.wt. polymer contained in the composition is added. This liquid mixture in a heated state is devolatilized by casting into a devolatilization tank having a sufficient space to a volatile component content <1wt% to obtain a methacrylic resin comprising a high-purity polymer component. When the amount of the phosphorus ester added is below 0.01wt%, no effect can be brought about, and when it is above 0.5wt%, such addition is not only economically undesirable because the coloration-preventing effect does not increase in proportion to the amount of addition but also undesirable because silver streaks are formed on a molding when the composition is injection-molded.

Title: Arq system
Inventor: ONISHI SHINJI
IPC: H04L1/18
Filed: 1990-10-19
Abstract: PURPOSE:To shorten a required transmission time while neglecting a small quanty of residual errors within an allowable range even when line environment is worse by measuring a residual error rate after performing error correction at a reception side, and issuing an affirmative reply not issuing a negative reply when the rate shows a value less than a prescribed value. CONSTITUTION:After the error correction in applied to an information block and a parity bit at an error correction circuit 6 based on an error correction code attached on the information block at the reception side, odd/even check is performed in relation with an error-corrected parity bit in accordance with the character bit string of an error-corrected information block. Furthermore, the residual error rate of residual error in the whole one information block is measured by an error detection counter 7, and when it is less than the prescribed value, the re-transmission of the information block with small residual errors is prohibited by issuing the affirmative replay, not the negative reply. Thereby, it is possible to shorten the required transmission time because the small quantity of residual errors within the allowable range can be neglected even when the line environment is worse.

Title: Loop type lan hybrid multiplexing system
Inventor: ABE KIYOSHI
Filed: 1984-12-31
Abstract: PURPOSE:To cope with its large capacity easily at a high speed by a combination of an asynchronous system packet switching circuit and a synchronizing system line switching circuit by constituting a titled system so that a packet switching circuit part of plural nodes uses a synchronizing bit position of a PCM frame as a time by taking synchronization to a time division multiplex transmission line interface. CONSTITUTION:Each node 30 is constituted of a loop access controlling circuit 31, a circuit switching device part 32, and a packet switching device part 33. This multiplexing system has an asynchronous oscillator to a transmission line 1, and also can take a timing buffer of a one bit portion of a synchronizing bit position at every one frame (193 bits), therefore, an oscillator of low accuracy can be used. A circuit 33A is constituted of the same interface as the circuit switching device, knows the synchronizing bit position by receiving a frame synchronizing signal from the controlling circuit 31, eliminates (n) pieces of data of that position, and brings data of (n)X192 bits to multiplex separation. In this way, it is unnecessary to provide an oscillator synchronized with a loop transmission line, an elastic buffer delay time of the data is small, and it can be transferred continuously so as to be asynchronous to all bits.
