Patent JP-S642307-A (JP)
Title: Superconducting coil device
Inventor: MITSUNE SUSUMU
IPC: H01F6/00
Filed: 1987-06-25
Abstract: PURPOSE:To shorten excitation time to ease excitation operation thereof and reduce heat penetration thereinto for thereby protecting the captioned superconducting coil, by serially connecting two sets of superconducting coils different from each other in their magnetically stored energy and further connecting via a protective resistor, a connection point between a power supply and one of the superconducting coils with an intermediate lead led from a connection point between the superconducting coils. CONSTITUTION:A superconducting coil l with less magnetically stored energy and that 2 with more magnetically stored energy, both constructing a cryostat, are serially connected to each other, whereby only one power supply 6 is available for their excitation to shorten excitation time and ease excitation operation. In addition, a protective resistor 3 is connected between a connection point between one terminal of the power supply 6 and one end of the superconducting coil l, and one end of an intermediate lead 5 exposed to the atmosphere, which resistance is less than that of the coil l upon its being quenched. Hereby, a current having been flowing through the coil l upon its being quenched is allowed to substantially flow through the resistor 3. This assures almost no consumption of the magnetically-stored energy in the coil 2 through the coil l for reducing heat penetration into those coils for the purpose of protection of the coil l and hence prevention of burning of the same.

Filed: 1987-06-25
Abstract: PURPOSE:To improve the operability of a magnetic recording and reproducing device by incorporating a small-sized tape cassette adapter and providing a moving means for moving a standard tape cassette and a moving means for moving a tape driving device. CONSTITUTION:When the small-sized tape cassette holder 11 is pressed in at a solid-line position where the standard tape cassette 27 is inserted into an insertion slot 3, a slide arm 15 rotates counterclockwise from a solid-line position to a broken-line position. At this time, the cassette holder 11 and cassette 27 are guided by guide grooves 12a and 12b and recorded or reproduced at the position of the tape driving device 20. When a small-sized tape cassette is recorded or reproduced, the small-sized tape cassette is loaded in the adapter 8 fixed at a position shown by an alternate long and short dashes line from an insertion slot 6 made in a ceiling plate 5. Here, when the operation switch of a front panel 2 is pressed, the tape driving device 20 moves from a broken- line position to a solid-line position as shown by an arrow A and recording or reproduction is performed there.

IPC: F02D41/14
Filed: 1991-06-28
Abstract: PURPOSE:To improve responsiveness of feedback control for air-fuel ratio of a mixture, in the case of using alcohol-contained fuel in an engine. CONSTITUTION:At normal time, alcohol fuel A in a fuel tank 22 is injected supplied from a secondary side injection valve 16, and on the other hand, at engine starting time and cold time or in a high intake air amount region, gasoline G in a fuel tank 30 is injected supplied from a primary side injection valve 15. At feedback control time of air-fuel ratio of a mixture at normal time, in the case of a deviation of actual air-fuel ratio from target air-fuel ratio in a preset value or more, the gasoline G of large heating value is injection supplied as a correction fuel amount in the air-fuel ratio feedback control. Thus as compared with the case of using the alcohol fuel of small heating value as the correction fuel, the correction fuel amount is decreased thus to decrease a fuel adhering amount to an internal wall of an intake passage 11 and also quickening supply of fuel to an operating chamber 7 to contrive improvement of fuel consumption by improving follow-up responsiveness of the air-fuel ratio feedback control.

Title: Cushioning material made of corrugated board and production thereof
Inventor: KAWAKAMI HAJIME
IPC: B32B7/02
Filed: 1993-06-29
Abstract: PURPOSE:To reduce an empty space between the packed article and packing box and improve cushioning function by elastic deformation before buckling, by cutting a corrugated board laminated-material, and corrugating one or both end faces intersecting the flute axis. CONSTITUTION:A cushioning material 1A is obtained by cutting a corrugated board laminated-material, by corrugating one end face 2 intersecting the flute axis, and by making the other end face 3 flat. The corrugated part of the cushioning material 1A has a shape consisting of a beam 4 and a pillar 5 supporting it, the beam 4 can slightly bend and also the lower part of the pillar 5 is small in ground contact area, therefore, when a vertical load is applied, the pillar 5 itself receives compression more or less and elastically deforms as a whole. Thus, the cushioning material does not exert adverse effect on a packed article, and the paper product can be easily disposed of after use, compared to foam plastic products.

IPC: H02H3/24
Filed: 1987-06-24
Abstract: PURPOSE:To shorten time delay when A.C. power interruption is detected, by forming a reference voltage corresponding to a specific ratio of A.C. peak voltage, then comparing actual A.C. voltage with the reference voltage and forming a square pulse train for judging power interruption. CONSTITUTION:A.C. voltage is fed from an A.C. power source to a reference voltage generating means 11 arranged in a converting means 10 so as to form a reference voltage corresponding to a specific ratio of A.C. peak voltage. Preferably, the specific ratio is set to 68-73%.

Filed: 1991-06-28
Abstract: PURPOSE:To obtain a driving system for ultrasonic motor in which stability is enhanced at the time of intermittent rotation by a constitution wherein a control circuit is subjected to vibration suppressing control when a detecting means detects an exciting vibration. CONSTITUTION:A control circuit 3 for ultrasonic motor delivers the current position of a stage 1, detected through a position sensor 4, to a switching control circuit 5 where the current position is compared with an externally provided target position. A selection is then made between a continuous operation and an intermittent operation based on the decision whether the difference is larger than a predetermined distance or not. A feedback circuit 10 in the control circuit 3 detects the exciting oscillation of a piezoelectric element and thus detected exciting oscillation is fed back to a duty control circuit 8. Upon receiving the exciting oscillation, the duty control circuit 8 temporarily interrupts duty control or continuous rotary driving and performs vibration suppressing control.
