Filed: 1995-04-28
Abstract: PURPOSE: To expand compressed image data without deteriorating quality of the image and to reproduce a video signal at a high speed as a master device for a cell video tape manufacturing device. CONSTITUTION: A frame separator 101 separates compressed image data received at a high speed for each frame and outputs a frame detection signal and it is given to a data distributer 102. The data distributer 102 distributes compressed image data received from the frame separator 101 to four decoders 103-106 according to the frame detection signal sequentially for each frame. The four decoders 103-106 decode the respective compressed image data into an original image signal and provide an output of the decoded signal to four time base compressing devices 107-110 respectively. The four time base compressing devices 107-110 applies time compression to the received image signal for 1/4 and provide an output to a signal synthesizer 111.  The signal synthesizer 111 synthesizes sequentially the image signals from the four time base compressing devices 107-110 and provides an output of a high speed video signal.

Abstract: PURPOSE:To enable accurate, simple and quick inspection by employing a mechanism which performs a vacuum suction of with a printed circuit board placed between a floating mobile plate and an upper mobile plate to keep the entire surface of the printed circuit board by a uniform force. CONSTITUTION:An inspector of printed circuit boards supports a probe needle 2 at the upper part of the printed circuit boards 1 supported on a floating mobile plate 31 with a support plate 5 to keep the probe needle 2 in contact with the top of the printed circuit board 1. At this point, a vacuum suckable area 4 is formed in the perimeter of the printed circuit board 1 to suck an upper mobile plate 35 vacuum by a suction means communicating with the area 4 so that the substrate 1 is pinched between the floating mobile plate 31 and the upper mobile plate 35. Then, the support plate 5 is moved to make the probe needle 2 abut the top of the substrate 1 being pressurized. Thus, the entire surface of the substrate 1 can be sucked on the upper mobile plate 35 by a uniform force to keep the probe needle 2 in contact with the substrate by a even load thereby enabling accurate measurement.

Title: Control system for semiconductor manufacturing equipment
Inventor: IKEGAMI HARUHIKO
IPC: H01L21/205
Filed: 1992-04-24
Abstract: PURPOSE:To control the dispersion in the film quality of wafers by eliminating wait time caused by the overlap of a wafer load of unload time at a precedent reaction chamber and that at a subsequent one in forming films simultaneously in these two reaction chambers in a semiconductor manufacturing equipment provided with only one transport mechanism. CONSTITUTION:After film formation data (film formation recipe) has been outputted to the control unit for a precedent reaction chamber, the shortest time difference from this time of the output is found and it does not causes any overlap. Then, after the time difference has passed, the film formation data is outputted to the control unit for a subsequent reaction chamber. The wafer load or unload time for each reaction chamber varies depending upon the position in which the previous operation of a transport mechanism was stopped. To cope with this, load and unload times are tabulated for every combination of previous transport operations and current ones, and this table has table been stored. The time difference is found based on this table.

Base on a public key, a plain sentence (x), that is to be ciphered and transmitted, is J divided to obtain a plain sentence vector (m). Moreover, a random number vector (r), that is not necessarily transmitted, is obtained. Then, a message vector (m') having K elements is obtained by coupling the vectors (m) and (r). Thus, the vector (m') is expressed as integers using the vector B. Then, an inner product of the vector (m') and public key vector (c) is obtained, the vector (m') is ciphered and a ciphered sentence C is obtained. The generated sentence C is transmitted to a receiving side entity (b) from the transmitting side entity (a) through a communication path 3.

Abstract: PROBLEM TO BE SOLVED: To prevent the damage of an inner electric wire, even if it is interfered by an obstacle from the outside, by forming the thickness of a mountain part projected to the outside of a bellow shape electric wire insertion pipe thicker than the outer part. SOLUTION: A bellow 2 is made of a flexible material such as a rubber alike the installation parts 1A, 1B and constituted by repeating a mountain part 2A and valley part 2B mutually. The thickness of the bellow 2 is same as that of the valley 2B, but the outside of the mountain part 2A is formed thicker gradually than a belly 2C which is a middle point of the mountain part 2A and valley part 2B. As the thicker of the mountain part 2A projected to the outside of the bellow 2 is made thicker than that of other part, even if the bellow 2 is interfered by an obstacle, it is not crushed perfectly and also the bellow 2 is not contacted to the electric wire after breaking. As the thickness of the mountain part 2A of the bellow 2 is thicker gradually than the belly 2C, a force for bending is dispersed and also a cushion effect can be raised.
