Title: Manufacture of semiconductor device
Inventor: ADACHI HIROKI
IPC: H01L21/20
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To form a thin silicon oxide film on the surface without affecting a material of a substrate and form a thick insulating film covering the silicon oxide film to obtain a gate insulating film of a desired thickness, by heat- annealing an island-like crystalline silicon film using light of a specified wavelength in an oxidizing atmosphere. SOLUTION: After an amorphous silicon film is formed by a plasma chemical vapor deposition(CVD) method and is annealed and crystallized in a nitrogen inert atmosphere, the silicon film is patterned to form an island-like silicon film 103. Then, the silicon film 103 is irradiated with an infrared light having a wavelength of 0.5 to 4 μm in an oxygen atmosphere, thus forming a silicon oxide film 104 on the surface of the active layer 103. Moreover, a silicon oxide film 105 having a thickness of approximately 1000 Å is formed as a gate insulating film by a plasma CVD method. Subsequently, an aluminum film is formed by a sputtering method and is patterned to form gate electrodes 106 and 108.

IPC: H01L21/8242
Filed: 1991-08-28
Abstract: PURPOSE:To prevent an electrode FIN from being bent and from making contact with a nitride film by forming a film comprising a different substance from that of the electrode FIN at least on one of the upper and lower surfaces of the capacitor electrode FIN. CONSTITUTION:A poly Si film 10 has internal strain at the lower surface thereof owing to its having been joined with a CVD SiO2 film. Metal silicide such as tungsten silicide (WSi) or a metal film 11 is formed on the upper or lower surface of the poly Si film 10 or opposite surfaces of the same so as to moderate the distribution of the internal strain. Hereby, there is prevented the poly Si film 10 from being bent, which is caused by a heat treatment in a process where a SiO2 film as a capacitive insulating film is formed on the surface of the poly Si film 10 through a thermal oxidization process, and in processes thereafter.

Title: Fault detection system
Inventor: SATO KUNIHIKO
IPC: H04L69/40
Filed: 1984-10-17
Abstract: PURPOSE:To detect the loop state of a line by allowing a data transmitter at the transmission side to insert a unique address with an opposite data at least in a transmission frame and checking it at the reception side. CONSTITUTION:Each data transmitter 1 has a specific address and this address is given to all transmission/reception frames. A transmission section of a transmission station reads an address of the own station from a built-in memory and inserts it to a field A of the transmission frame. A reception section of a reception station compares an address of the field A of the reception frame with the address read from the built-in memory and when they are not coincident, the reception frame is regarded to be correct. When the reception station detects a frame error as the result of the check of the field A, a line between data transmitters transmits a message a loop state to a station being a management center to block the line between the data transmitters.

Title: Control device for 4-wheel-drive
Inventor: KAWAMOTO MUTSUMI
IPC: B60K23/08
Filed: 1985-09-30
Abstract: PURPOSE:To prevent generation of a slip, by furnishing a device to shift to the 4-wheel-drive provided that the car acceleration becomes remarkably smaller compared with the variation rate of the accelerator opening in a 2-wheel-drive. CONSTITUTION:The driving force from an engine is delivered to a torque converter 21, a main transmission 22, and a sub-transmission 23, and the output is transmitted to the front wheel driving shaft 26 through a differential unit 25 to operate a 2-wheel-drive. On the other hand, signals from detectors 1 and 2 are input to an arithmetic unit 3, where the ratio of the acceleration to the variation rate of the accelerator opening at the time is computed and input to a comparing-and-deciding unit 4. In the unit 4, the present computing value and the computed value a moment ago are compared, and if the present value is smaller than the other, the 4-wheel-drive signal is generated by a signal generator 6. Therefore, since the car is shifted to the 4-wheel-drive in a larger driving force condition, the generated driving force can be delivered sufficiently to the road surface, a slip is prevented, and a safe running condition can be realized.

Title: Controller for sine-wave converter
Inventor: SHIMIZU HIROKI
IPC: H02M7/219
Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To reduce the sizes and the cost of a sine-wave converter by advancing the phase of a line current flowing to a three-phase AC power source from that of a regenerated current outputted from a power rectifier means when regenerated energy is generated. SOLUTION: When regenerative operation is made, the output voltage of a motor 4 is converted into a direct current by means of a reverse-converting circuit 3 and the current is used for charging a smoothing capacitor C0 . As a result, the output voltage of the capacitor C0 is converted into a three-phase AC voltage by means of a power rectifier circuit 2. Then the circuit 2 outputs an output voltage *VCRS and, because of the voltage *VCRS, a regenerated current *IRC which flows to a three-phase AC power source 1 from the circuit 2 flows through a connecting line SR. The current *IRC is divided into a capacitor current *IC and an R-line current *IR and the current *IC flows to a capacitor CR and the current *IR flows to the R-phase of the power source 1.  When the regenerated current *IRC flows, in addition, a voltage drop *VLR occurs across a coil LR and the phase of the current *IR advances.
