Title: Manufacture of semiconductor device
Inventor: HIROFUJI YUICHI
IPC: H01L27/108
Filed: 1987-07-15
Abstract: PURPOSE:To reduce a leakage current between a cell plate and a substrate and improper breakdown strength rate by forming a thick insulating film only in the bottom of a trench groove by a predetermined method. CONSTITUTION:A thermal oxide film 4 is formed on the inner face of a trench groove 3 formed on an Si substrate 1. Then, an Si film 5 is formed by a vacuum depositing method or a sputtering method on the surface. Thereafter, the film 4 is removed with aqueous solution of hydrogen fluoride or ammonium fluoride. Since the bottom of the groove and the surface of the substrate are protected with Si films 5', 5, the lower film 4 is not removed, but only the film 4 of the sidewall is removed. When it is heat treated again in an oxidative atmosphere, the films 5, 5' are oxidized, and a thermal oxide film 7 is newly formed on the sidewall. As a result, a thick thermal oxide film is formed only in the bottom.

Filed: 1985-08-09
Abstract: PURPOSE:To reduce the redundancy of a compression code by generating and adding a fill bit when code data generated by counting a bit number of the code data and a coded line number does not meet the minimum transmission time. CONSTITUTION:A control section 14 counts up a generation code counter 19 every time a coder 13 outputs one clock to count a bit number of a generated code data and counts up a coded scanning line counter 18 every time the coder 13 outputs a one line coding end signal to count the coded line number, and when the count of the counter 19 is equal to or exceeds a block data bit number specified in advance, the data generation of one block is finished to generate a fill bit to the said block. When the fill bit number F to the block is positive, since the block does not meet the block minimum transmission time, F-set of fill bits are generated and sent to a S/P conversion circuit 15.

Title: Logical operation circuit
Inventor: YASUDA YASUSHI
IPC: H03K19/013
Filed: 1980-12-15
Abstract: PURPOSE:To reduce the number of elements to obtain a superior integrated circuit, by connecting a transistor for discharge to the base of a phase dividing transistor and the collector of an output transistor. CONSTITUTION:The base of a transistor TRT9 for discharge is connected to a phase dividing TRT4, and the collector of the TRT9 is connected to the base of an output TRT6 through a diode D2. Consequently, the base electric charge of the TRT6 is discharged to the earth by turning-on of the TRT9. The diode D2 is provided for accelerating the transient of the phase dividing TRT4 to turn-off. Thus, the number of required TRs is reduced, and an active pull-down circuit requiring resistances is unnecessary. Since the TRT9 and the diode D2 are formed on the same isolation, the occupied area of the circuit on a chip is reduced.

Title: Charge stopping device in flash light generation device
Inventor: KIJIMA SEIICHI
IPC: G03B15/05
Filed: 1987-07-17
Abstract: PURPOSE:To prevent the wasteful consumption of electric power by stopping the oscillating action of a transistor according to the detected voltage at the time when the charged voltage of a main capacitor reaches a specified value. CONSTITUTION:When charging is advanced and the charged voltage of the main capacitor 28 reaches the charged voltage Vo, a transistor 30 receives the voltage of a tap (a) in its base and is turned on so as to stop the on and off oscillation of a switching transistor 20. When an output current i2 is stopped by the stopping of oscillation, fly-back voltages are generated in the respective coils of a booster transformer 21 and the transistors 20 and 30 remain off. Thus, the charging action is stopped according as the main capacitor 28 obtains the charged voltage Vo, but the charged voltage actually becomes Vo+DELTAVo because there is a slight time difference from the time when a base current is applied to the transistor 30 to the time when the output current i2 is stopped. Then divided resistances and the transistors for amplification, etc., are not needed, so that the power consumption can be reduced.
