Title: Wafer support member
Inventor: INOUE HIRONORI
IPC: H01L21/683
Filed: 1994-09-29
Abstract: PURPOSE: To form a wafer support member using an aluminium nitride material sintered body and at the same time, to contrive to provide a high-resistance layer having a volume resistivity higher than that of the aluminium nitride material sintered body, which is a parent material, at the contact sites of the wafer support member with a wafer. CONSTITUTION: As the contact sites of a wafer support member with a wafer 20 consist of a high-resistance layer 13, an electrostatic suction of the wafer 20 due to a Johnson-Rahbeck force is prevented from being generated and after a process ends, the wafer 20 can be easily demounted from the wafer support member. As a result, the throughput of the wafer 20 is improved and a mixing of impurities can be also prevented.

IPC: F02D41/22
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To ensure detection of abnormal combustion, even if constantly weak, in a diesel engine and to specify a cylinder in which abnormal combustion occurs. SOLUTION: A vibration sensor 11 is mounted on an engine block 20 and only the signal of a specified frequency band is picked out of signals output by the vibration sensor if by an electric filter 12. Further, a signal corresponding to a combustion timing for each of cylinders is picked out by a signal processing circuit 13 and a value obtained by arithmetic processing of the signal is compared with a previously stored judgement level of each of cylinders by a CPU 14 in order to judge whether abnormal combustion occurs or not in each of cylinders.

Title: Tape running control system
Inventor: YOSHIDA SHIRO
IPC: G11B15/467
Filed: 1986-10-03
Abstract: PURPOSE:To always execute stable tracking by detecting a signal length of a specific ATF (Auto Track Finding) position signal at every frame of a recording signal, and executing a decision of an even or odd frame by deciding only the odd frame. CONSTITUTION:A reproducing signal output from a reproducing amplifier 2 supplies a signal of a difference to an ATF SYNC signal selecting circuit 26 from a comparator 25 through a BPF 24, extracts selectively an ATF position signal, and sends out an SYNC length discriminating output from an ATF position signal length discriminating circuit 28 through a number of waves counter 27. The ATF position signal of one frame portion and two tracks is stored by a shift register 28, and simultaneously, parallel output signals RG1-RG4 are outputted. Subsequently, in one frame, when the signal length of three pieces or more of ATF position signals amount four pieces is decided as '1' block, it is decides as 'odd frame', and a frame decision output state is maintained for a prescribed time. In such a way, generation of what is called a pseudo-lock state can be prevented completely.

Inventor: HASEGAWA SHINICHI
IPC: H02P6/08
Filed: 1999-08-24
Abstract: PROBLEM TO BE SOLVED: To start or stop rotation of a recording medium at high speed. SOLUTION: A DSP 10 outputs an SPSB signal being a start signal of a spindle motor 2 to a spindle driver 15 and a monomulti vibrator 16. The mono- multi vibrator 16 outputs a rectangular wave of low of a prescribed period to a base of an NPN transistor 17.

Then, in the spindle motor 2, as a current inputted from the spindle driver 15 is made smaller, the motor is rotated with low acceleration. And when a signal outputted to the base of the NPN transistor 17 from the mono- multi vibrator 16 is restored to high, the impedance between the collector and the emitter is made smaller, and as the current inputted from the spindle driver 15 is made larger, the spindle motor 2 is rotated with the high acceleration.

Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To recover data even on the occurrence of one-shot frame missing or a data error by multiplexing a plurality of a preceding data string and a current data string with one frame, adding a regular code to each frame and sending the resulting frames. SOLUTION: In the data transmission system of a single direction form where each frame is sent sequentially, a preceding data string and a current data string are multiplexed on one frame, a frame identification code (DIVC) subjected to regular I/O change and a check code (CRC) to detect a data error in a frame are added to each frame and the resulting frames are sent. At a receiver side, CRC is checked for each frame and a data string is separated and stored in memories (left, right). When the result of CRC check is other than 'Z', it indicates an error in an in-frame data and the frame data are thrown away. When a change in a frame identification code is 1→1 in a (n+2)th frame as shown in figure, missing of a (n+1)th frame is found out. In this case, data from the left and right memories are outputted to obtain data (c), (d) so as to prevent missing in the data string.
