Title: Arithmetic unit
Inventor: FUJII KUNIHIKO
IPC: G06F7/52
Filed: 1988-03-31
Abstract: PURPOSE:To compose the arithmetic unit of minimum circuits by repeating addition and subtraction according to the shift quantity of an input and obtaining an optional coefficient value. CONSTITUTION:This unit consists of a shifter 11 which shifts an input signal, an arithmetic circuit 12 which performs arithmetic operation with the output of the shifter 11 and an output signal, a multiplexer 13 which selects an initial value with the output of the arithmetic circuit 12 and the output signal, and a register 14 which holds the output of the multiplexer 13 for a unit time. Then the shifter 11 operates in such a direction that the power of 2 is obtained and addition or subtraction is carried out only when a necessary shift quantity is obtained during the period and the arithmetic value is stored in the register 14. Then a shifter 11 operates in such a direction that one over the power of 2 is obtained, and addition or subtraction is performed by a necessary quantity to obtain a desired coefficient value. Consequently, the optional coefficient values are obtained without entailing an increase in circuit area.

Title: Optical transmission line fault point search system
Inventor: RYU SHIRO
IPC: H04B3/46
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To search fault points on all optical transmission lines inside a ring with an optical time domain refrectometer(OTDR) device by transmitting an optical signal for fault point search through an optical fiber transmission line inside an optical network while bypassing plural node devices with a branch optical fiber. SOLUTION: On both the input and output sides of node device 1-1 and 1-2, wavelength division multiplexing(WDM) couplers 20-1, 20-2 and 30-1 to 30-4 are respectively inserted as branching means and synthesizing means and the branch ports of the WDM couplers 30-1, 30-3, 30-2 and 30-4 are mutually connected by optical fibers 40-1 and 40-2. Then, the wavelength band of an optical signal outputted from an OTDR device 10 is set different from that of an optical signal outputted from the node device and only the optical signal outputted from the OTDR device 10 can be transmitted while bypassing the node device 1-2. Therefore, since the optical signals outputted from the OTDR device 10 are successively transmitted while bypassing the respective node devices, the fault points on all the transmission lines can be searched by one OTDR device 10.

Title: Method of measuring surface temperature of object
Inventor: WATANABE KUNITOSHI
IPC: G01J5/00
Filed: 1980-06-16
Abstract: PURPOSE:To enable accurate measurement of temperature irrelevant to frequent occurrence of unsatisfied reflection requirements of a mirror surface by calculating  the radiation factor and the temperature of an object based on maximum and minimum values of the output of a radiation thermometer for a long term. CONSTITUTION:A block body furnace 14 is provided at a central port 20 of a water-cooled shielding plate 18 fitted with a furnace wall 10, while a radiometer 16 is provided at opening 24 thereof. When the radiometer 16 receives radiation energy following the movement of the view, the output thereof indicates the maximum and minimum values. As oscillated surface of a running strip 12 will hamper the satisfaction of the reflection reguirement of the mirror surface, the peak may disappear  in some cases. As this oscillation is cyclical, the output of the radiometer is measured for a long term enough to cover the cycle of the oscillation and the results of  the measurement are processed statistically to obtain the maximum and minimum  values of the output. Computation using the values enables accurate measurement of the radiation factor and the temperature of the strip 12.

Title: Alternate interrupter
Inventor: SAKURAI YASUHIKO
IPC: B60Q1/38
Filed: 1980-06-16
Abstract: PURPOSE: To protect a circuit against troubles cause by the unloaded high voltage of an electric source by providing a circuit to keep one of two lamps lit when another lamp is disconnected.  
     CONSTITUTION: When a flasher lamp 109 is disconnected and then winker switches 105a and 105b are thrown into the right, a charging circuit is off to a condenser 18, and the circuit is not operated. Consequently, a flasher lamp 107 is continuously lit. In case the flasher lamp 109 is disconnected during on-off operation, when a relay is off and a contact 1 is on the side of break, the condenser 18 is discharged by a resistance 15. If this discharging time is kept shorter than the off-time of the relay during the normal on-off operation, the condenser 18 is perfectly discharged during the off-time of the relay, and cannot be again on. Therefore, the lamp 107 is continuously lit.

Abstract: PURPOSE:To prevent a slip generated by the frequency difference by detecting the frequency difference between a clock of a time division switch and a clock of a data communication equipment, changing the data bit length in response to the frequency difference and adding change identification information to identify the change in the data bit length. CONSTITUTION:A bit control circuit 6 adjusts the pulse number per one unit of a read clock BRK so that the count of a phase difference detection counter 5 reaches a preset value. A transfer data added by a change identification information bit and a bit length identification bit by a change identification information insertion circuit 7 is sent to a time division switch 3. A bit detection circuit 8 identifies the data bit length based on the change identification information and generates the buffer memory write clock BWK in response to the data bit length. Further, the buffer memory write clock BWK is sent to a clock recovery circuit 10, which recovers the transfer timing clock RT of the data communication equipment 1 by averaging the missing clock based on the write clock BWK.

Title: Method for identifying bar code in bar code detector
Inventor: SATO TAKESHI
IPC: G06K7/00
Filed: 1993-04-08
Abstract: PURPOSE:To reduce the size of a bar code detector by detecting a margin indicated by a bar code at first, checking the width of the detected margin and then executing bar code character identifying processing corresponding to the detected sort. CONSTITUTION:A bar code is read by a scanner and the width of black and white parts of the bar code is calculated by a width measuring part 2. The calculated width data are temporarily stored in a width data memory 3 and then converted into a character code by a code analyzing part 4 using a microcomputer or the like. At the time of reading out the bar code width data from the memory 3, the code analyzing part (microprocessor) 4 judges whether the width of the margin is larger than a prescribed width or not based upon the width data of the margin. Namely the margin is common to any bar code label even when the sort of the bar code is different, so that the existence of the margin and the validity of its width are checked at first, and then processing is transferred to a bar code identifying procedure corresponding to the sort.

Thus, the inclining deformation of the cover 1 caused by an impact, removal of an under cut part 4 from the outer peripheral edge of the bush 23 and falling-off of the cover 1 are prevented.
