Title: Semiconductor device and manufacture thereof
Inventor: YAMAZAKI YOICHI
IPC: H01L29/732
Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device and the manufacture thereof whereby the characteristics variation of a bipolar transistor due to B contamination is suppressed to realize a high reliability and a manufacturing yield. SOLUTION: In a semiconductor device involving mixedly V-pnp bipolar transistors and L-pnp bipolar transistors, a p-type B diffused region 62 is formed between an n+ type base buried layer 14b and an n-type base region 17b of the L-pnp bipolar transistor. The B diffused layer 62 purposely formed on those regions where contaminant B may be distributed to have influences on the characteristic of the L-pnp bipolar transistor will cancel the influences of the contaminant B, even if the B contamination occurs in forming the base buried layer 14b. Thus the characteristic variation of the L-pnp bipolar transistor due to B contamination (and the contamination level) can be prevented.

Filed: 1988-08-17
Abstract: PURPOSE:To avoid excessive data output by inputting a code to control the propriety for output of the business transaction data and outputting the business transaction data only when the input code satisfies the specific conditions. CONSTITUTION:A CPU 1 retrieves a single commodity file and prepares a single commodity list which satisfies the output conditions. At the same time, the CPU 1 counts the single commodities that satisfy the output conditions. Then the number of the single commodities and displayed on a display device 5. An operator checks the displayed number of single commodities and inputs '2' if this number is improper. While the operator inputs '0' in case the displayed number of single commodities is proper and can satisfy the output conditions. Furthermore '1' is inputted in case only the display is desired for the number of single commodities that satisfy the output conditions. The next process is controlled in response to an input command. In other words, an input command shows '0', a single commodity list that satisfies the output conditions is printed by a printer 6.

Abstract: PURPOSE:To prevent the mixing of oil and abrasion dusts into the compressed fluid in a bellows by partitioning the inside of a cylinder in which a piston moves in reciprocation by the bellows, in a reciprocation type fluid compressor equipped with the bellows. CONSTITUTION:When a piston 6 shifts downwardly in a cylinder 5 in each stage of a multistage compressor having a plurality of compression mechanisms in symmetrical form, the fluid II in the cylinder 5 partitioned by the bellows 7 is compressed, and at the same time, also the inside compressed fluid I is compressed through the bellows 7. When the fluid I obtains a prescribed pressure, a valve 10 is opened, and the fluid I is sent to the next stage, passing through a cooler 11. When the piston 6 reaches the bottom dead center, the valve 10 is closed. Then, a valve 9 is opened, and the piston 6 starts elevation, and the compressed fluid in the bellows 7 is absorbed. Since the compressed fluid I is absorbed and discharged from the space separated from the cylinder space, the mixing of lubricating oil and the abrasion dusts of the piston can be perfectly prevented.

Title: Radio communication system with automatically selected transmission frequency
Inventor: JIEEMUSU UOOREN SUMISU
IPC: H04B1/7156
Filed: 1988-08-19
Abstract: PURPOSE: To prevent the mutual interferrence of a radio communication system by receiving a prescribed radio frequency signal and transmitting the radio frequency signal in response to a control signal showing a start signal and this radio frequency signal are not to be received for prescribed time. CONSTITUTION: In response to the start signal to be generated when a system CS1 is powered up for the first time, recovered from the loss of synchronism or recovered from the loss of a signal or another previously designated system state is generated, a start sequence is started at the place of the CS1. A control module (CM) 1 listens to prescribed frequencies F1 and F2 while using receivers 110 and 112. When the frequency F1 and/or the frequency F2 is detected, the CM1 is determined as a subordinate CM system and in respose to the control signal showing neither the start signal nor the radio frequency signal is received from transmitters 109 and 111 for the prescribed time, the F1 and F2 are transmitted. Thus, the mutual interferrence of the radio communication system can be prevented.

Title: Da converter
Inventor: ANDO TAKASHI
IPC: H03M1/66
Filed: 1986-08-29
Abstract: PURPOSE:To contrive to effectively improve picture quality with inexpensive constitution by inputting an input digital signal to a difference detection circuit with an adjacent signal and changing the time constant of an integration circuit receiving a DA-converted analog signal in response to the result of detection. CONSTITUTION:When a digital signal Di is inputted and the difference between adjacent signals is small as below, since the detection signal S of a detection circuit 3 goes to L, an analog switch SW 7 of the integration circuit 2 is turned off and the time constant of the integration device 8 is larger as R2C2. When the difference between the adjacent signals is large as over 2, since the signal S goes to H, the SW 7 is turned on, resistors R2, R3 are connected in parallel and the time constant of the integration device 8 is decreased. Thus, an output analog signal A0 being the result of integration 2 of the analog signal A1 converted by the DA converter 1 changes smoothly for the part with less change in the signal Di, and the signal A0 changes steeply so as to follow the change when the change in the signal Di is large. Thus, the gradation is continuous smoothly with a small gradation change and the boundary is made clear with a large gradation change in the picture quality.
