Title: Manufacture of semiconductor device
Inventor: YAMAKAWA YOSHIAKI
IPC: H01L29/812
Filed: 1990-01-31
Abstract: PURPOSE:To enable the recess width of a FET to be arbitrarily controlled while forming a gate metal in the central part of the recess and also enabling the gate shape having no trailing at all in the lower part of the gate to be taken by a method wherein three layers of thin films are used in the case of the formation of the recess and gate and after the formation of the recess, one more layer is further used. CONSTITUTION:An oxide film 2 formed as the first thin film layer, another oxide film 3 formed as the second thin film layer, a nitride film or titanium silicide or tungsten silicide film 4 formed as the third thin film are grown on a semiconductor substrate 1 surfaced with an active layer and then a photoresist film 5 on specific pattern is formed on the film 4. Next, when the whole thin films are etched with an etchant to accelerate the etching rate of the oxide film 2 higher than that of the oxide film 3 using the photoresist 5 as a mask, the oxide film 2 is side-etched. Next, the substrate 1 is etched away to form a recess using the oxide film 2 as a mask and then the other oxide film 6 (the fourth thin film) is grown on the recess next, the oxide film 6 is etched again to deposit a gate metal 7 on the whole surface so as to complete a semiconductor device by cutting the metal 7 using a patterning process.

Title: Data buffer with compression function
Inventor: FUJIWARA TSUNEO
IPC: G06F5/00
Filed: 1989-01-31
Abstract: PURPOSE:To reduce the capacity of a first-in first-out memory by compressing continuous same data into one, loading it on the first-in first-out memory and loading continuous numbers in the other first-in first-out memory. CONSTITUTION:When data which appear on an input data bus 4 continue as same data, a load control circuit 30 stops the transmission of same data for the first-in first-out memory (FIFO) 10 through a load signal line 3. A counter circuit 50 and a counter selection circuit 60 simultaneously count the number of the appearing times of same data by a control signal outputted to a control signal line 10, generates an identifier selecting one of counters 1 in the circuit 50, and loads it on FIFO 20 through a data line 8. At an unloading time, the identifier which has counted the number of continuous times is outputted on an output data line 2 from FIFO 20 and an unloading circuit 40 stops unloading until a counting value which the counter holds comes to zero. Thus, the capacity of the memory can be reduced.

A reference capacitor 8 provided at the lowermost part is always immersed in liquid. Liquid paths 10 are provided at a plurality of parts in the longitudinal direction in the pipe 5. The liquid can be inputted and outputted at the part from a measuring capacitor 7 provided at the uppermost side to the capacitor 8. The electrostatic-capacity signals of the capacitor, which is completely immersed in the liquid, and the capacitor 8 are equal. The difference occurs between the electrostatic-capacity signals of the capacitor 7, which is completely exposed on the liquid surface, and the capacitor 8. The depth of the liquid is obtained by confirming these electrostatic- capacity signals.

Title: Recording tape information code system
Inventor: NAKAMURA KEIICHI
IPC: G11B5/02
Filed: 1981-02-20
Abstract: PURPOSE:To prevent error on understanding a message recorded on a recording tape, by automatically recording recorded date, time and its number actually for the message and automatically displaying them on the reproduction. CONSTITUTION:The contents of dictation by a caller are recorded on the 1st channel of a tape 6. A controller 4 converts an information code such as date, time and number and the like into a burst signal by turning on or off an analog switch 2 by the number times corresponding to the numeral, e.g. ''3'', and records them on the 2nd channel of the tape 6. At the reproduction of the information code recorded on a tape 11, when a burst signal representing the numeral ''3'' for example, an output of a decoder 14 becomes three pulse signals. A controller 15 reads in the information code and display it on a display 16 by counting the pulse signals from the decoder 14. Thus, the error in understanding the content of message can be avoided.
