Abstract: PURPOSE:To improve the degree of an indexing and rotating accuracy by installing an angle indexing ball train to the support shaft in a direction of thrust force through a flexible disk. CONSTITUTION:From the original angular position, for instance, when an angle 60 deg. is angularly indexed, an operating handle 22 is turned once in a direction of loosening, and a ball 13a in a ball train 13, engaged with a V-groove 17 of a positioning member 16, is restored by the elasticity of a flexible disk 8 together with a ball holding ring 10 to cause a support shaft 4 to be rotatable.

Filed: 1988-01-27
Abstract: PURPOSE:To provide a tolerance to noise margin by providing a circuit means controlling a voltage of a DC reference voltage source depending on an output signal of a comparator. CONSTITUTION:A voltage of an input reference voltage terminal 34 of a comparator 12 is set by two positions at a terminal 6 with a switch 11 turned on and at a terminal 5 within the voltage of them and the voltage at the terminal 34 is controlled by switching the voltage at the terminal 6 depending on the ON/OFF of the switch 11. A voltage V34 at the terminal 34 is switched in a direction opposite to the compared voltage in a way such that the voltage at the terminal 34 is brought into a low voltage when the voltage at the terminal 6 is high and the voltage at the terminal 34 is brought into a high voltage when the voltage at the terminal 6 is low. Thus, the input reference voltage at the input terminal 34 of the comparator 12 is controlled by a voltage at a control terminal 37 being an output terminal of the comparator 12. Thus, the margin of the input signal level to be handled and the noise margin are improved.

Abstract: PURPOSE:To improve the heat-resisting property of a FET to which a gold electrode is formed, and to shorten a process by a method wherein an insulating film being coated is removed by a resist mask, while the gate section of a semiconductor surface is exposed, and the surface is coated successively with a barrier metal and gold and lifted off. CONSTITUTION:An N type GaAs operating layer 2 grown on a semi-insulating substrate 1 is coated with the film such as a SiO2 film, one parts of the film 3 are removed and source and drain electrodes 4, 5 are shaped, and the film 3 on a gate region is removed through a method, by which side etching is decreased, by the resist mask 7. The surface is coated with the barrier metal 9, such as Pt, Mo, etc. through sputtering, and an Au layer 10 is evaporated from the vertical direction. The resist film 7 is removed and the surface is lifted off, and a gate electrode 11 is completed. Accordingly, the contact of the Au layer 10 of the electrode 11 and the GaAs layer 2 can be prevented, the heat-resisting property is improved and reliability can be ameliorated. Since clearances can be difficult to be formed among the gate electrode 11 and the SiO2 film 3 and the GaAs surface is not exposed, a succeeding protectively layer forming process can be unnecessitated, and the process can be shortened and cost can be reduced.

Title: Data creating device for region cutting
Inventor: HASHIMOTO MASAHITO

Filed: 1987-01-27
Abstract: PURPOSE:To reduce the time for data to be input, by calculating a tool running line pitch for an input shape data to generate its outermost periphery to be left in the fixed direction running of a tool when the simple geometric shape data is input to plural optional positions, in the case of milling. CONSTITUTION:A shape data input part reads a shape data, input on the basis of a machining parts drawing, to store in memory a kind of the data, coordinates, machining region, size, etc., and a crossing point data calculating processing part B performs a process of offsetting a tool radius and a finishing margin from the shape while calculates a tool running pitch so as to generate no cut residue, calculating crossing point coordinates from the obtained running line and the shape data after being offset.

In this way, the time for data input can be reduced by enabling the region cutting data to be automatically created.

Title: Timing circuit
Inventor: SATOU HITOSHI
IPC: H03K5/133
Filed: 1978-02-15
Abstract: PURPOSE:To obtain a timing circuit of high time precision with inspection and assembling times shortened by selecting several outputs of a 1st-stage delay line by a switch and by inputting the selected outputs to a 2nd-stage delay line. CONSTITUTION:For example, the memory-unit timing circuit consists of access control circuit 1 which receives start signal REQ0 or REQ1 and adjust contention to drive delay line 2 at the 1st stage, and switch 3 which selects output signals (a0) to (ai) of delay line 2 and drives delay-line group 4 generating memory-unit timing. Since delay-time deviation among outputs of delay-line group 4 is a little although four kind of signals for memory-unit timing are outputted from delay-line group 4, determining output signal RAST results in the determination of other three output terminal positions. Therefore, an inexpensive timing circuit of high precision can be obtained through assembling processes small in number only by checking the delay time from REQ0 to RAST and by adjusting switch 3.
