Title: Run-length coding and decoding device
Inventor: TAKEDA TAKASHI
IPC: H04N1/419
Filed: 1982-08-26
Abstract: PURPOSE:To decrease the frequency of memory access and to speed up decoding processing, by providing a means for counting 0s in an input code, and deciding on the starting address of a memory to be accessed on the basis of the counting result. CONSTITUTION:Since an input 00001011 contains four 0s, a zero counter counts up to four and the contents Z of a memory address corresponding to the counted value are retrieved and read out; and the next data ''0'' is added thereto to obtain an address X+0 to be read next. Then, contents 02 and the next data ''1'' are added to the address X+0 to obtain an address X+3 to be read. Similarly, the contents and the next digit ''1'' of the input data are added to the address to obtain an address X+5 to be read next. The contents B0 of the address are 10100000 in binary notation and the most significant digit bit is ''1'', so the address X+5 is a terminal node and the 2nd digit is ''0'' indicating a terminating code, so the following six digits are used to read white run length 48 corresponding to a binary notation number 110000, thus completing the decoding.

Title: Evaluation method for field effect transistor
Inventor: YANO HITOSHI
IPC: G01R31/26
Filed: 1994-06-29
Abstract: PURPOSE:To obtain a method for evaluating a field effect transistor even if the drain lag amount thereof is low. CONSTITUTION:The pulse width of final stage output pulse voltage is measured when the input mark rate is close to 0 and 1, respectively, for an integrated circuit comprising a multistage cascade connection of inverter circuits, i.e., direct coupled FET transistor logic circuits. The drain lag amount of the FET constituting the inverter is evaluated based on the variation of the pulse width. The rising and falling times of the inverter fluctuate depending on the fluctuation DELTAI of the drain lag amount, i.e., the drain current, from a DC value. Since the direction of the fluctuation is reversed between the even and odd stages, the pulse width is varied after passing through a multistage inverter. The DELTAI is determined utilizing the fact that the amount of fluctuation is varied depending on the mark rate. Since the variation of pulse width increases as the number of stages increases, the measurement can be made without sacrifice of the sensitivity even if the DELTAI is decreased.

Title: Production of flux cored wire
Inventor: SAKAI YOSHIYA
IPC: B23K35/40
Filed: 1982-08-24
Abstract: PURPOSE:To produce a flux cored wire having uniform quality and high performance with good productivity, by inclining a steel straight pipe, feeding a powder and granular flux from the opening end in the top part and packing the flux in the pipe then drawing the pipe. CONSTITUTION:A steel straight pipe 1 is inclined to 20-65 deg. angle theta of inclination, and a power and granular flux F is supplied from the opening end in the top part into the pipe 1, whereby the flux is uniformly packed in the pipe in a short time. If the above-mentioned angle theta is <=20 deg., the speed of packing is low and if >=65 deg., the rate of packing is made nonuniform as an abnormal increase in packing density is resulted from powdering during packing. The steel pipe 1 packed uniformly with the flux at a high speed by the above-mentioned method is drawn whereby the flux cored wire having stable quality is obtd. with good efficiency. The flux is packed by using a steel spiral pipe having 30-70 deg. lead angle, whereby the reduction in the size of a building is made possible.

Title: Rectifier
Inventor: HANEDA SHOJI
IPC: H01L21/8222
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To enable A.C. rectification with a simple configuration and a low loss. SOLUTION: A base B and a subemitter S of p-type semiconductor are joined to a collector C of n-type semiconductor, so as not to contact each other. An emitter E of the n-type semiconductor is jointed to the base B. A resistor R is connected between the base B and emitter E, a positive terminal of a biasing power source VB is connected to the emitter S, and a negative terminal thereof is connected to the emitter E. When the collector C and emitter E have substantially the same potential, a continuity is made between the base B and sub- emitter S to develop a voltage drop across the resistor R, but no continuity is made between the collector C and the emitter E. When the voltage of the emitter E is further reduced with respect to the voltage of the collector C as a reference, continuity is established between the collector C and emitter E.

Abstract: PURPOSE:To secure continuance of the repeating action for the transmission line signals through formation of the optical by-pass circuit even when the optical transmitter has some trouble by installing the optical branch part, the optical cut-off part and the optical coupling part each between the transmission lines of the input and output sides. CONSTITUTION:Optical branching unit 12 is provided between the transmission lines of the input and output sides, and input optical signal Si is divided into two parts through branching half-mirror 12b. Thus reflected light Sr of one side is led into optical receiver 14; while transmitted light Sp of the other side is led into shutter 16b of optical breaker 16 each. Light Sr goes up to receiver 14 and then converted into the electric signal to be supplied to the reception circuit, and at the same time converted into the optical signal again at optical transmitter 22 via signal switch gate 21 to be delivered via optical coupler 18. On the other hand, light Sp actuates shutter driving circuit 16c by the optical by-pass command to open shutter 16d to be delivered through coupler 18. Accordingly, the repeating action can be continued for the transmission line signal even when transmitter 1 has some trouble.

Title: Semiconductor device
Inventor: KASUGA TOSHIO
IPC: H01L21/60
Filed: 1978-11-29
Abstract: PURPOSE: To enhance device reliability through facilitated positioning of lead wire and preventing its position from shifting by providing depression on the surface of protruded electrodes or bumps.  
     CONSTITUTION: Au layer 12 on metal barrier layer 16 is masked by resist film having width slightly larger than that of lead wire 13, on which Au layer 12' is further formed. This permits a depression 17 having the contour of the lead wire 13 to form on the surface of protruded electrode or bump. In order to connect the protruded electrode, the lead wire 13 is simply inserted in the depression 17. This eliminates unstable operation for positioning and thus enhances device reliability. The depression-inserted lead wire 13 cannot be moved by external force in connecting operation and thus contributes to device reliability.

Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To allow the radio fixed terminal equipment to report the operation of the equipment by a backup battery on the occurrence of a power failure and the remaining operation available time to the user. SOLUTION: In the radio fixed terminal equipment 1, a voltage management means in a control section 21 acquires an input DC voltage to a power supply circuit 12. A comparison control means in the control section 21 compares DC voltage information preset in advance with a measured DC voltage to discriminate whether or not the equipment 1 is driven by a DC voltage from an AC/DC adaptor 15 or a DC voltage from a charging battery in a backup charging battery unit 16. When the equipment 1 is driven by the charging battery, the operation available time of the terminal equipment 1 is calculated by the measured DC voltage.  Thus, the drive power supply type identification information and the operation available time information obtained in this way are reported by a notice means in the control section 21 to the user audibly or visually, then the user selects how to use the terminal equipment 1 depending on the status.
