Title: Pinball device with ball return device
Inventor: MIZUNO KATSUJI
IPC: A63F7/02
Filed: 1991-11-07
Abstract: PURPOSE:To allow players to continue pinball to their heart's content by electrically combining a ball return device with a count device and providing an adjustment means which adjusts the amount of prize balls and the amount of balls to be returned. CONSTITUTION:A ball supply button 70 and a ball return device 72 are provided between adjacent two pinball machines 6.

CONSTITUTION:The inner part of a rotor 1 is composed of a multiple tube, of which the central part is a tube for putting a low-temperature refrigerant into the central part of said rotor and surrounded by a vacuum heat insulating layer 3 to reduce the auantity of heat entering said low-temperature refrigerant. Outside said tube, there exist multiple tubes 12, 12' for cooling a superconducting coil in the inner part of the rotor and for discharging the refrigerant outward. In the sidewall of said central tube 13, a low-temperature refrigerant inlet hole 10 passes through the heat insulating layer 3; said tube 13 is surrounded by an irrotational case 2' via a narrow gap 14; and the inside thereof is covered by a vacuum layer 3' to enable reducing the quantity of heat entering the low- temperature refrigerant from the outside to a small one. Also, a magnetic fluid seal 4 is arranged on both sides of a low-temperature refrigerant inlet pipe 7 to prevent the low-temperature refrigerant from leaking outward. Thus, the refrigerant such as liquid helium can be put into the rotor stably.

Abstract: PURPOSE:To automatically perform the variable operation of a transmission/receiving frequency by transmitting the variable information of an audio receiving frequency with an optical signal from a remote controller to an audio euqipment and permitting the audio equipment to make an audio transmission frequency coincide with the receiv ing frequency corresponding to the optical signal. CONSTITUTION:When a frequency variable key (a) of a key pads 42 of a remote controller 45 built in an FM radio is pressed, the frequency information is transmitted to a PLL oscillator 37 and an output circuit 44 via a microcomputer 43. Receiving the information, the oscillator 37 supplies a frequency f2 to a demodulation circuit 33 of an FM radio 36, and the circuit 44 converts the information into an optical signal and supplies it to a light receiving part circuit 13 of a TV receiver 27 built in an FM transmitter. By means of the optical signal, the circuit 13 supplies the frequency f2 to a modulation circuit 24 performing the FM transmission of TV broadcasting audio received by a TV receiver 12 via a PLL oscillator 17. Thus, the FM transmitter and radio can perform automatic transmission/receiving at the same frequency designated by the key pads 42 and the change of frequency due to noise, etc., can be facilitated.

Title: Line controller
Inventor: YAMAGUCHI HIROSHI
IPC: H04Q3/58
Filed: 1988-12-16
Abstract: PURPOSE:To restart normal communication to a terminal equipment using other line by detecting a line fault and switching an extracted clock having the fault into an extracted clock from a normal line. CONSTITUTION:When a line L=1 is broken, it is detected by both a communication error detection circuit 9 and a feeding detection circuit 10 and when a fault takes place without a broken line, it is detected by the communication error detection circuit 9. A digital line control section 6 informs the occurrence of a communication fault to a call control section 14 via a path C1. A call control section 14 stops synchronizing with an extracted clock CK1 from the digital line control section 6 and gives a command to take synchronization with the extracted clock from other normal line. Thus, resynchronization with a digital line network is taken to other terminal equipment 4 or 5 and normal communication is restarted.

IPC: H05K3/34
Filed: 1997-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a method for efficiently forming an electronic component with a highly reliable solder junction. SOLUTION: Solder set between two components is melted in a chamber 8 that is filled with a gas having a lower oxygen concentration and a higher thermal conductivity than those of the normal atmosphere under a pressure low enough to obtain the same temperature profile as under a normal pressure. Then, while the soldering temperature is maintained, the pressure inside the chamber 8 is rapidly increased immediately before the molten solder is solidified so that voids in the molten solder 3 are compressed. Consequently, the solder volume is reduced.

Title: System for dividing index storage area
Inventor: SEGATA SUKEYOSHI
IPC: G06F12/00
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of a page use which does not become the storage destination of continuous key values and to improve the page use rate as a whole by adjusting a storage destination page with the key value which is logically positioned in the center as a reference in a key value group in the page. SOLUTION: If an entry having a key value '28' is added when the entries which continuously have '27' from the key value '22' are added, they are added in the latter half with the entry having the key value '23' which is logically Positioned in the center of an index page P2 as the reference. Thus, a boundary is decided between the entry group to the entries having the key value '27' which is smaller than the key value '28' of the added entry and which is the nearest and the remaining entry group containing the entries having the added key value '28'. The entry group which does not contain the entry having the added key value '28' based on the decided boundary is moved to an index page P3 and a division processing is completed.
