Title: Branch trace control system
Inventor: NISHIOKA JUNJI
IPC: G06F11/28
Filed: 1985-12-17
Abstract: PURPOSE:To reduce the quantity of hardware by checking whether a branching source address and a branched address are included within previously set upper and lower limit addresses by an existing arithmetic circuit. CONSTITUTION:The upper and lower limit addressed of the branching source address and the branched address are stored in an LS area 51 of a main storage in addition to a pointer and a byte counter. When a branching condition is formed and branching is executed, the branching source address and the branched address are set up on one input of the arithmetic circuit (ALU) 1 and the upper and lower limit addresses stored in the specific area are extracted and set up to the other input to execute four operations. A carry/output zero detecting circuit 9 inputs a carry output to be '1' when the calculated result of the ALU 1 is a negative value and a zero output to be '1' when the calculated result is zero to test the input.

Title: Semiconductor random access memory
Inventor: ARIMOTO KAZUTAMI
IPC: H01L21/8242
Filed: 1985-12-16
Abstract: PURPOSE:To allow a peripheral circuit to operate at a high speed while allowing a memory cell to have increased resistance to soft errors, by biasing wells having a first type of conductivity in the peripheral circuit to a supply voltage while biasing wells having a second type of conductivity in the peripheral circuit to a negative voltage. CONSTITUTION:A well W0 of a memory cell is biased to a second voltage. Wells W1, W2 and W3 having a first type of conductivity in a peripheral circuit are biased to a first voltage VCC, while wells W3 and W5 having a second type of conductivity in the peripheral circuit are biased to a third voltage VBB. For example, the p-type well W0 is biased to a ground voltage, the p-type wells W3 and W5 to a negative voltage (=VBB), the n-type wells W2 and W4 to a supply voltage and the n-type substrate 1 is to the supply voltage. An n-type MOS transistor in the peripheral circuit 2 is thereby back gate biased to a negative potential and the floating capacity is decreased. Thus, the peripheral circuit 2 is allowed to operate at a high speed. Further, an n-type MOS transistor in the memory cell is back gate biased to a ground voltage and the width of the depletion layer thereof is decreased. Thus, the the memory cell is allowed to have an improved resistance to soft errors.

Title: Optical transmission equipment
Inventor: HIRATA KENJI
IPC: H04B10/11
Filed: 1987-11-11
Abstract: PURPOSE:To attain communication even while the transmitter is being moved independently of the location and direction of the optical transmitter by constituting a light emitting section and a photodetection section by plural photodetectors. CONSTITUTION:In case of the communication between optical transmitters A, B, when the transmitter A gives a call to the transmitter B, an operation button 9 of the transmitter A is turned onto attain transmission enable state. When a voice is fed toward a microphone 1, the voice signal is amplitude- modulated by a modulation amplifier section 2 and given to the light emission section 3, where each light emitting element 3a radiates a light in all directions in response to the modulation signal. In such a case, even if both the optical transmitters A, B are moved, part of the light radiated from the transmitter A reaches the optical transmitter B to attain communication at all times. This is applied similarly also in case of the communication from the transmitter B toward the transmitter A.

Title: Processing system for display of object attribute list
Inventor: KATAYAMA YOSHIHIRO
IPC: G06F17/21
Filed: 1986-11-29
Abstract: PURPOSE:To easily cope with change, etc., of object attribute names by compiling a list of necessary object attributes for display based on an object attribute control list in an input mode of object attributes. CONSTITUTION:The correspondence is secured by an object attribute control list 16 between the object attribute codes and the object attribute names that are identified by users. Thus the correction is required for the list 16 only when the object attribute names are added, changed and deleted. Then it is not required for each processing part executed by a processor 10 to be conscious of each concrete object attribute name. In other words, an object attribute list 17 is automatically corrected just by changing and adding data on the list 16 when the object attribute names are changed and added. Thus no change is needed for a program to be executed by the processor 10.

Abstract: PROBLEM TO BE SOLVED: To provide an optical head device that is characterized by the capability of obtaining a detection signal for a minute error, with two gratings arranged, by the angle signal of Moire fringes, against a focusing error on an optical disk or against the multilevel of a pit.

Filed: 1994-11-21
Abstract: PURPOSE: To provide an electric heating type moxibustion apparatus capable of operating with a single hand and stably radiating a far infrared ray by applying a thin hard ceramic with superior far infrared radiation characteristic to a moxibustion contact part and applying a heater made of ceramic in which a heating line is assembled in a bushing made of ceramic to the inside. CONSTITUTION: A heating line ceramic assembling type heater 15 as the heater made of ceramic is assembled in a moxibustion contact 3 made of ceramic. Moreover, uniformity and stability for thermal conductivity can be improved by filling aluminum powder 19. Also, heat insulation is performed by filling a rock fiber 18 so as not to heat the hand while this apparatus is being used. A grip handle 4 is formed in a two-dividing type, and an apparatus switch 2 for temperature switching adjustment of strong/disconnection/weak level is mounted on one side of the grip handle. A neon bulb 5 is mounted, and it is operated so as to put on while energizing the apparatus and to put off when it is de-energized, which prevents the disconnection of a power source from being forgotten.  When the moxibustion contact 3 made of ceramic is housed in the inside of the grip handle 4, unnatural stress due to variation of tolerance can be prevented from being applied by bonding it with an adhesive 10.

Title: Screw pipe-type stay anchor

Title: Fitting method for optical connector head
Inventor: IDE TAKASHI
IPC: G02B6/36
Filed: 1988-11-11
Abstract: PURPOSE:To prevent an optical fiber element wire from being caught when it is inserted by heating and applying the exposed optical fiber element wire with a tensile force and forming a smooth tapered part at its end part. CONSTITUTION:The tip part 12a of the optical fiber element wire 12 which has the smooth tapered part is much smaller than the diameter of the insertion opening 31 of an element wire insertion hole 3, so the element wire is easily inserted into the element wire insertion hole 3. The tapered part increases in external diameter gradually to the diameter of the element wire insertion hole 3, so the optical fiber element wire 12 moves into the insertion hole 3 while guided by the insertion hole 3. Here, the tapered part of the tip part 12a is made smooth, so the element wire is hardly caught. Consequently, even if the optical fiber element wire tip part 12a deviates slightly from the center of the element wire insertion hole 3, smooth insertion is possible unless the tip part 12a is off the insertion hole 3.
