Title: Magnetic bubble memory device
Inventor: AKIBA YUTAKA
IPC: G11C19/08
Filed: 1985-04-26
Abstract: PURPOSE:To improve the reliability of a chip connecting part by exposing a lead wire for connecting a chip on a wiring board from the center part of a chip mounting part to the external direction and bonding a magnetic bubble memory chip on the center part side of the chip mounting part. CONSTITUTION:The leads 9a for wiring for connecting the chip on the wiring board FPC is exposed from the center part of the chip mounting part 1 to the external direction and the chip CHI is bonded on the center part side of the chip mounting part 1. Since the coil COI is heated, the influence of heat stress upon the bonding part should be reduced. Since the flexible wiring board FPC is weak, the bonding part is protected from artificial or mechanical stress to be applied to the chip mounting part 1 from the completion of a board assembling body to the fixing process of the BND to a case RFSa.

Title: Void-detecting apparatus
Inventor: YOKOKURA KUNIO
IPC: G01R31/12
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To provide a void-detecting apparatus of high insulation performance and high reliability. SOLUTION: In the void-detecting apparatus, a commercial frequency is added from a commercial frequency power source 1. A magnetic flux of a core (iron core) of a saturable reactor 2 is changed in accordance with a change of a time-integrated voltage. The core is saturated when the magnetic flux exceeds a predetermined value, whereby an inductance of the saturable reactor 2 is decreased to charge a charging capacitor 3. As a result, a pulse voltage appears at both ends of the charging capacitor 3. The pulse voltage is pumped in accordance with a turns ratio of a transformer 4 and impressed to a coupling capacitor 5 and a sample device 6. A void present in the sample device 6 is detected in this manner. Operation safety of the void-detecting apparatus is improved.

Abstract: PURPOSE: To utilize a clamping device as a driving device for an assembly necessary for a printer by providing a clutch which can connect with and separate from a direction changing roll which can be driven in the reversible rotational movement depending on the rotational direction for a connected inked- ribbon drive shaft. CONSTITUTION: A direction changing roll 5 performs reciprocating motion in the rotational directions 7a and 7b in corresponding with a recording head carriage 1 performing reciprocating motion in the directions 6a and 6b. The direction changing roll 5 is rotatably supported in a carrier casing 8. The direction changing roll 5 transmits a driving force only in one direction of the rotational directions 7a and 7b. This intermittent driving force is generated by means of a clutch 9 of an inked-ribbon drive shaft 10 for an inked-ribbon cassette. An intermediate gear 19 can be reciprocatedly slid against the force of a one arm-like spring 22 by its bearing journal in a longer and circular arcuate guide member 20 to form the clutch 9 thereby. Movements in the movement directions 23a and 23b generate action of the clutch 9.

Title: Device for controlling fluid level in electric discharge machining bath
Inventor: HOSODA HIROSHI
IPC: B23H7/36
Filed: 1990-04-05
Abstract: PURPOSE:To secure prevention of leakage of electric discharge machining fluid from a connected portion of an extendable pipe and an exit port of the electric discharge machining fluid in an electric discharge machining bath by connecting one end of the extendable pipe to the exit port of the electric discharge machining fluid in the electric discharge machining bath, and also by easily sealing the connected portion through keeping another end of the extendable pipe upwards at arbitrary height. CONSTITUTION:Fluid level in an electric discharge machining bath 2 is set by keeping an opposite opening 6b of an extendable pipe 6 communicated with an exit port 3 of the fluid in the electric discharge machining bath 2 upwards at arbitrary height. When the fluid level in the electric discharge machining bath 2 reaches the height of the opposite opening 6b of the extendable pipe 6, the fluid overflows the opposite opening 6b and the fluid level in the electric discharge machining bath 2 is kept to the set level. Thus, the connected portion of the exit port 3 of the fluid and one end of the pipe 5 can be sealed easily and tightly, and leakage of the fluid from the electric discharge machining bath 2 is prevented. Consequently, it is not necessary to adjust the fluid level monitoring the leakage and overflow of the fluid.

Abstract: PROBLEM TO BE SOLVED: To lower the signal levels and to fast transmit the codes by extracting the noises of higher harmonic components flowing to a power line, detecting the existing sections of extracted noises and transmitting a prescribed signal in a section other than the detected ones. SOLUTION: The signals are transmitted and received between a master station A and a slave station al via a power line P, i.e., a transmission line in a time band when no noise exists after the noise gaps are detected on the line P. In other words, the low frequency components at high levels are eliminated from a constant current source supplied to the line P by a BPF 5 and the noises are generated at a prescribed interval. These noise existing sections are detected by a noise section detection circuit 9. When the station al receiver a transmission request signal from the station A, the prescribed information generated by an information processing circuit 3 is sent to the station A at a low level via a transmitting circuit 7 in a section other than the noise existing ones that are detected by the circuit 9.
