Title: Production of semiconductor device
Inventor: ENOMOTO TATSUYA
IPC: H01L21/306
Filed: 1977-12-02
Abstract: PURPOSE: To prevent shortcirauiting of wirings by beforehand providing a conductor film on a semiconductor substate, superposing a wiring metal thereon then performing anodic oxidatin thence removing unnecessary conductor films.  
     CONSTITUTION: Conductive poly-Si 8 is laminated on an insulation film 2 having openings 9 and an Al layer 3 is made. Next, masks 4 are formed and the exposed part is converted to porous alumina 5 through anodic oxidation. At this time, formation current is supplied from the underlying layer 8 to the entire region of the Al layer 3 and the porous alumina is surely formed to the circumferences of wiring parts 3a thru c. when it reaches the layer 8, the formation stops. Next, only the layer 8 is completely etched away through the pores of the porous alumina 5 by a CF 4  gas, whereby a hollow part 10 is formed. This construction prevents shortcircuiting between the wiring parts 3 with themselves.

IPC: B21B11/00
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To obtain larger effect of promotion of plastic deformation and to miniaturize an vibrating device by providing a pressurizing cylinder for sucking/ discharging a working fluid from/to an vibrating cylinder and providing the vibrating device for reciprocatively driving the pressurizing cylinder so as to follow a cam by rotational driving force to a roll group. SOLUTION: Back-up rolls 7, 8 and the cam 14 are driven at the same time by the rotational driving force imparted from the output shaft of a driving device to working rolls 5, 6. Then, the pressurizing cylinder 19 is followed by the shape of the outer peripheral surface of the cam 14, a piston 17 is reciprocatively driven, the suction and discharge of the working fluid are repeated and the vibrating cylinder 24 which is connected to the pressurizing cylinder 19 is reciprocated and a working roll 5 is vibrated. Because the outside diameter of the piston 22 of the vibrating cylinder 24 is larger than that of the piston 17 of the pressurizing cylinder 19, the displacement of the piston of the vibrating cylinder 24 is smaller as compared with that of the pressurizing cylinder 19 and vibrating force becomes larger.

Title: System and device for reception
Inventor: KATAYAMA YOSUKE
IPC: G06K17/00
Filed: 1990-06-05
Abstract: PURPOSE:To demodulate a digital data from an information signal without using a filter or a frequency/voltage converter while avoiding any influence caused by noise by transmitting the digital data as the information signal which frequency is converted. CONSTITUTION:When a non-contact IC card 2 is loaded to a reader/writer 1, a transmission line is formed by magnetically coupling a coil 4 of the non- contact IC card 2 and a coil 3 of the reader/writer 1. When transmitting the digital data from the reader/writer 1 to the non-contact IC card 2, the frequency of a carrier for power supply is converted by the digital data. Then, the information signal, which frequency is converted by the digital data, is received and a part having a level higher than a previously set threshold value in the information signal is detected. Then, by comparing the time width with the reference time of each part, a signal is generated so as to get the low level in the part having the time width longer than the reference time and to get the high level in the part having the time width shorter than the reference time. Thus, the digital data in the information signal is obtained.
