Title: Semiconductor integrated circuit device
Inventor: USUI TOSHIMASA
IPC: H01L21/82
Filed: 1986-04-22
Abstract: PURPOSE:To improve wiring capability by a method wherein two types of basic cells which have sizes defferent from each other are employed and the same type of cells are arranged laterally and the two types of cells are alternately arranged longitudinally. CONSTITUTION:A basic cell 1 is composed of P-type channel transistors 9 and N-type channel transistors 10 and a source wiring 4 crosses the P-type channel transistors 9 which are composed of polycrystalline silicon gates 6 and P<+>type diffused regions 7 and a GND wiring 5 crosses the N-type channel transistors 10 which are composed of polycrystalline silicon gates 6 and N<+>type diffused regions 8. A basic cell 1' is composed of P-type channel transistors 9' which the source wiring 4 does not cross and N-type channel transistors 10' which the GND wiring 5 does not cross. In the arrangement wiring process, if the number of wirings of the circuit is not so large, functional blocks are provided on the basic cells 1 and the regions on the besic cells 1' are used as wiring regions and, to the contrary, it the number of wirings is too large to be arranged on the basic cells 1' only, functional blocks are provided on the basic cells 1' and the regions on the basic cells 1 are used as wiring regions. With this constitution, the basic cells can be efficiently utilized and high wiring capability can be obtained.

Title: Impedance matching circuit
Inventor: NISHIYAMA SUMI
IPC: H03H7/38
Filed: 1985-05-02
Abstract: PURPOSE:To obtain an impedance matching circuit stable to mechanical vibration by forming a capacity controlling circuit element by a parallel connection element consisting of a fixed capacitor and a variable capacitor. CONSTITUTION:A capacity control part is constituted of a variable capacitor 2 having the minimum variable range necessary for covering the dispersion range of its control capacity and a chip capacitor 1 enabled to obtain its necessary control capacity accordance with in parallel connection to the variable capacitor 2 so that the chip capacitor 1 is arranged and connected on/to the lower part of the variable capacitor 2. Since a capacity variable range approximately corresponding to the dispersion range of the control capacity is obtained, the capacity control is not sharply influenced by the variation of the control position of the variable capacitor 2. Thereby, even if capacity control work is not so precise as compared with the ordinary method, impedance matching can be attained, and even if the control position of the variable capacitor is slightly shifted due to mechanical vibration, the impedance matching is not sharply shifted. Thus, stable impedance matching can be obtained.

Title: Chemical vapor deposition apparatus
Inventor: KOYAMA KENJI
IPC: H01L21/31
Filed: 1989-04-12
Abstract: PURPOSE:To nearly completely capture produced fine particles and to prevent them from adhering to a semiconductor substrate again by a method wherein electrodes are arranged on the downstream side from a film-formation zone of a gas stream in a growth reaction chamber, a high-frequency electric dis charge is generated and an excess gas is transformed into a plasma and adheres to the electrodes. CONSTITUTION:Electrodes 7 are arranged on the downstream side 16 from a film-formation zone Z of a gas stream in a growth reaction chamber 11; a high-frequency electric discharge is generated; an excess gas is transformed into a plasma and adheres to the electrodes 7. That is to say, the gas which has been heated and excited in the film-formation zone Z and which has not yet become a growth film completely is applied, as the growth film, between the electrodes 7 where the high-frequency electric discharge has been generated. In addition, even when the gas has become fine particles, they are captured firmly by the electrodes 7. Thereby, it is possible to reduce that the fine particles are added to the growth film; a film quality of the growth film can be enhanced.

Title: Semiconductor device
Inventor: NAKAHARA KAZUHIKO
IPC: H03G5/02
Filed: 1988-04-15
Abstract: PURPOSE:To make the resonance frequency of a resonance circuit variable so that various frequency bands can be set with one semiconductor device by constituting the resonance circuit of a capacitor, inductor and FET whose source and drain are connected in parallel with the inductor. CONSTITUTION:A peaking circuit is constituted of a capacitor 4, inductor 3, and FET 5 which is connected in parallel with the inductor 3. Since the capacity between the source and drain of the FET 5 is variable due to a gate bias, the resonance frequency of the peaking circuit can be changed by changing the gate bias. Accordingly, the frequency band of a negative feedback amplifier can also be changed by changing the gate bias only without changing the parts constituting the circuit. Moreover, since the fluctuation, etc., of the characteristics between each semiconductor device can be eliminated due to the variable resonance frequency, a semiconductor device always having stable characteristics can be obtained.

Title: Inspection of sintered parts subjected to steam treatment
Inventor: SUZUKI NAOHIRO
IPC: G01N27/04
Filed: 1982-06-04
Abstract: PURPOSE:To select the propriety of steam treatment in an iron-based sintered alloy by measuring an electric resistance between two points of a sintered part subjected to the steam treatment. CONSTITUTION:When a sintered alloy being porous is subjected to a surface treatment such as carburizing, nitriding and plating, it is necessary to seal pores on the surface thereof beforehand and a steam treatment is employed for the purpose. The sintered material subjected to the steam treatment changes noticeably in the electric resistance depending on the propriety of the treatment. When the generation of an oxide film by the steam treatment is sufficient, the electric resistance indicates a high value. When it is not suficient or a carbon substance is attached to the surface thereof, the electric resistance indicates a low value. The measured value of the electric resistance is checked upon with the proper range of an electric resistance value as previously obtained by comparison of the electric resistance value to the results of the surface treatment for the same kind of parts to select the propriety of the steam treatment applied to the parts.

Title: Melting of scraps akin to ion contaminated by radioactive substances
Inventor: TOKUMITSU NAOKI
IPC: G21F9/30
Filed: 1990-04-12
Abstract: PURPOSE:To reduce transferring ratio to fume and dusts, in melting radioactively contaminated scraps akin to iron, by identifying temperature of molten ion, carbon content in the iron to be produced by melting, and weight ratio of calcium oxides to silicon oxides contained in a slag. CONSTITUTION:In order to suppress radioactive substances, a cesium in particular, to become fume and to be dispersed as dusts, and to remain them in a slag, it is required to make a molten iron of high carbon content. To keep melting temperature low and also to keep a basicity of the slag low. Accordingly, the melting temperature of the iron is made to lower than 1,400 deg.C and, for stable operation during the melting and keeping fluidity during tapping and founding, the carbon content in the molten iron is made to larger than 3%. The basicity of slag that is defined as weight ratio of calcium oxides to silicon oxides contained in the slag, is maintained to be more than 0.3% and less than 1.0% in order to suprress dispersion of radioactive substances. On those melting conditions, without owing too much cost for environmental counter measures such as treatment of the dusts, exhaust gases and discharging water, scraps akin to iron can be molten and therewith the radioactive substances can be transformed into the iron and safe vitric slag.
