Abstract: PURPOSE:To reduce a power consumption and to reduce an irregularity in an output current by a method wherein a first transistor, a resistance and a second transistor whose polarity is opposite to that of the first transistor are connected in this order in series between the power-supply side and the output side. CONSTITUTION:An N<-> epitaxial layer 8 is formed on one main face of a P-type silicon substrate 5 via N<+> type buried layers 6. An NPN bipolar transistor Q35 is constituted in such a way that an N<+> type diffusion region 15, a P-type diffusion region 11, formed inside the N<-> epitaxial layer 8, and an N<+> type diffusion region 16 formed in the P-type diffusion region are used as a collector extraction region, a base extraction region and an emitter extraction region, respectively. Accordingly, many NPN-type bipolar transistor, many diffusion resistances and many PNP-type bipolar transistors can be arranged to be adjacent. Accordingly, it is possible to reduce an irregularity in a voltage and a current amplification factor between a base and an emitter of the individual transistors and in a resistance value of the individual diffusion resistances; it is possible to reduce an irregularity in an electric current of individual outputs.

Title: Vtr timer
Inventor: SUZUKI TOSHIAKI
IPC: H04N5/44
Filed: 1979-12-28
Abstract: PURPOSE: To prevent the overlap set error of VTR timer picture recording reservation, by displaying contents, which have been reserved for recording, and contents, which will be reserved for recording, on the CRT display simultaneously.  
     CONSTITUTION: When contents for recording reservation are input to CPU8 from keyboard 7, CPU stores them. At the recording reservation time, CPU8 controls electronic tuner 6 where the channel is set automatically, deck mechanism control part 5 which controls tape running, and frame memory 9 which stores one-picture  components of characters to be displayed on CRT13. Characters stored in memory 9 are input to character generator CG10 synchronously with the synchronizing signal from timing circuit 11. The CG10 generates character picture elements and graph display picture elements to be displayed on CRT13 according to the input signal. A pattern to select graph display picture elements of CG10 by CPU8 and display the recording reservation time band with a graph is preset to memory 9 at the recording reservation time, and this pattern is displayed on CRT13 to prevent the overlap set error.

Title: Differential amplifier circuit
Inventor: NAGAYAMA YOSHIHARU
IPC: H03F3/347
Filed: 1984-08-22
Abstract: PURPOSE:To attain low offset by applying offset cancellation while a negative feedback loop for setting the gain of a differential amplifier circuit is opened. CONSTITUTION:A switch SW1 gives an input IN and a reference voltage Vref slectively to a non-inverting input IN(+) of a differential amplifier Amp. A switch SW2 switches an inverting input IN(-) to an output OUT or the non-inverting input (+). When the switch SW2 is thrown to the position of a contact (a), the offset voltage of the differential amplifier Amp. is amplified largely by the open loop gain and then outputted. The offset voltage output and the reference voltage are compared by a voltage comparator circuit VC to apply offset concellation. Since the offset voltage is amplified very largely, the offset voltage of the circuit VC itself is neglected.

Abstract: PURPOSE:To save labor in setting the photographing conditions and prevent erroneous setting by storing the final photographing conditions of the previous photographing for each local protocol, and setting the previous photographing conditions as long as person to be inspected is the same. CONSTITUTION:The standard photographing conditions, final inspectee key and final photographing conditions of the previous photographing are stored in a memory 2 for each local protocol.
