Title: Impurity diffusing method, semiconductor device, and manufacture of the device
Inventor: OKADA MASATAKE
IPC: H01L21/225
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To reduce the area of the peripheral area of an active area including guard rings. SOLUTION: In a semiconductor layer 35 which is laminated upon a substrate and in which an N-type impurity is added at a preset first impurity concentration, the impurity concentration of an area W1 surrounding an active area 36 containing a semiconductor element is increased from the first concentration by further adding the N-type impurity to the area W1. Then a P-type impurity is added to a plurality of annular areas surrounding the active area contained in the area W1 in nearly concentric states and diffused to a preset first depth. Consequently, guard rings 39-41 containing the P-type impurity and added layers 43-45 adjacently formed to the rings 39-41 are formed. The intervals among the rings 39-41 are narrower than those among the conventional guard rings and the area of the peripheral area including the guard rings is smaller than that of the conventional peripheral area.

Abstract: PURPOSE:To minimize a device so compactly, by limitting the number of hydraulic pressure control valves for an antiskid device to two pieces alone. CONSTITUTION:In case of a device which connects wheel cylinders with an X pipe line, a control unit 31 issues each command to both first and second control valves 4a and 4b controlling braking hydraulic pressure in wheel cylinders for each front wheel. And, a braking hydraulic pressure dropping command is formed by an OR in a first skid state to drop the braking hydraulic pressure in front wheels or rear wheels. In addition, the braking hydraulic pressure rising command after this dropping command passing away is formed by a second skid state of wheels of the side that the first skid state in the second skid state to make the braking hydraulic pressure for front wheels or rear wheels go up is preceded or passes away afterward.

IPC: F28F27/00
Filed: 1982-04-30
Abstract: PURPOSE:To prevent a heat exchanging liquid from mixing with another heat exchanging liquid by a method wherein the pressure of a circulation pump for the first liquid is made higher than that of a circulation pump for the second liquid and the pump for the first liquid is driven first when a heat exchange operation is performed. CONSTITUTION:The higher pressure pump 2 for the first liquid A is driven first and after detecting that a flow rate sensor 8 for the second liquid B indicates zero or the temperature indicated by a thermosensor 9 is within a predetermined temperature range, the lower pressure pump 6 for the liquid B is driven. In this case, the pressures of the pumps 2 and 6 are regulated such that the pressure indicated by a pressure sensor 4 becomes higher than the pressure indicated by a pressure sensor 7. Further, the above mentioned predetermined temperature range means a range of temperature variation of the liquid B when the liquid is kept standing without leaking at the time of starting the pressure feeding of the liquid A.

Title: Data transmission system
Inventor: YANAGIMOTO KOJI
IPC: H04L29/08
Filed: 1989-03-27
Abstract: PURPOSE:To suppress flag pattern transmission at no data and to eliminate the need for 0-bit insertion and elimination to make a flag pattern unique by fixing a frame length and providing a transmission frame for exclusive use of synchronism establishment or the like. CONSTITUTION:A frame length is fixed, a synchronization establishment exclusive use transmission frame 1, an idle frame 2, and a data transmission frame 3 are provided and the frames 1, 2 are used prior to the start of communication to establish the transmission frame synchronization. That is, each terminal equipment sends continuously the frame 1 to enter the synchronization establishment thereby urging the acquisition of an opposite terminal equipment and indicating it that its own terminal equipment is under acquisition simultaneously. Upon the establishment of reception synchronization, each terminal equipment sends the frame 2 continuously to inform the synchronization establishment to the opposite terminal equipment. Then the synchronization establishment of the opposite terminal equipment is awaited in this state and the mutual synchronization is established by receiving the frame 2. Succeedingly, the terminal equipment uses an identification header of the transmission frame to monitor the synchronization. Thus, the flag pattern transmission at no data is suppressed and the 0-bit insertion and elimination is not required.

Title: Battery having spiral electrode body
Inventor: FUKUOKA SATORU
IPC: H01M10/0587
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a battery which prevents a decrease in voltage during discharge and a decrease in discharge capacity by preventing a negative electrode from running out even if a positive electrode is placed on the outermost periphery of a spiral electrode body. SOLUTION: A manganese dioxide positive electrode 10 is made longer than a lithium negative electrode 30 by X. This elongated part serves as an extension 11a when the electrodes are combined into a spiral electrode body. The positive electrode plate 10 and the lithium negative electrode plate 30 are stacked with a separator 40 therebetween and wound into a spiral shape in which the lithium negative electrode plate 30 is located inside and the part of the extension 11a to which an insulator 14 is bonded is located on the outermost periphery, to form the spiral electrode body (a). Therefore the lithium negative electrode plate 30 does not exist on the inner periphery of the part of the positive plate 10 to which the insulator 14 is bonded, but since this part undergoes a discharge reaction with the same amount of positive electrode active material as do other parts, the discharge reaction proceeds uniformly over the entire lithium negative electrode plate 30 and the negative electrode can be prevented from running out.

Title: Evaluation of cavitation between cylinder liner and piston of internal combustion engine
Inventor: KUNIMOTO ETSUO
IPC: G01H1/00
Filed: 1983-04-27
Abstract: PURPOSE:To enable sharp cost-down by dispensing with a long-time durability test, by mounting a high frequency vibration detector to the wall part of a cylinder block while passing the output signal thereof through a bypass filter to block the low frequency component thereof. CONSTITUTION:A piezoelectric element 10 as a high frequency vibration detector is directly mounted to the outer wall part 4a of a cylinder block and connected to a bypass filter 11 which is, in turn, further connected to an amplifier 12. The bypass filter 11 is constituted so as to pass only a high frequency component among vibrations detected by the piezoelectric element 10. In this case, because vibration with blocking frequency of 250-300kHz or more is used with respect to the bypass filter, only ultrasonic wave of cavitation is enabled to pass and a long-time durability test is dispensed with and cost-down can be achieved.
