Title: Cutting device of printed board and cutting method thereof
Inventor: KUSE HIDEO
IPC: B26D9/00
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To prevent the burring of a side electrode by providing a drill for cutting the connection part side of a through-hole in a minute distance to partially peel the through-hole, and cutting the connection part by use of a disc-like grinding wheel. SOLUTION: The connection part 33 side of a through-hole 32 is cut in a minute distance by moving a drill with rotation or moving a master printed board to form a cut part 35 where the through-hole 32 is partially cut. According to this, since the cut part 35 is provided, a side electrode 34a is never burred even if the master printed board is cut by use of a rotating disc-like grinding wheel to form a slit 47. The reason is that the through-hole 32 formed on slave printed boards 31a, 31b is peeled on the connection part 33 side by the cut part 35. No burring is caused on the side electrode 34b side by the same reason.

Title: Thin film transistor, taper etching method and multilayered film forming method relative to the same, and image display equipment
Inventor: TAKANO TAKAO
IPC: G02F1/1368
Filed: 1994-05-18
Abstract: PURPOSE:To improve coverage of each film, prevent irregularity in a rubbing process, and exclude disconnection and short-circuit in each film, by working side walls of all constituting films in taper types, and laminating the films. CONSTITUTION:When constituting films are worked by using a dry etching method, a film 42 used in the upper layer part where the etching rate becomes high is in an overetching state, while a film 41 used in the lower layer part where the etching rate becomes small is etched. In the film 42 used in the upper layer part, etchback progresses in the whole part, during the etching of the film 41 used in the lower layer part. As the result, the side wall of the film 42 used in the upper layer part constitute a taper type etching form. The thickness of each film of a multilayered film constituting a TFT is adjusted and etching is performed, so that a taper form whose side wall has a desired taper angle is obtained. Thereby coverage of each film is improved, and disconnection and short-circuit in each film can be excluded.

Abstract: PURPOSE: To enhance the flow regulating function, while reducing the pressure loss, thereby to improve the measuring accuracy by providing a flow rate or speed measuring unit in a passage through which a fluid to be measured flows.  
     CONSTITUTION: There is disposed in a pipe passage 1 a Karman vortex flow meter 2 acting as a fluid measuring unit.

Title: Inverter apparatus
Inventor: KADOFUJI KIYOTAKA
IPC: H02P27/08
Filed: 1990-04-19
Abstract: PURPOSE:To prevent the destruction of a power transistor in an inverter circuit by containing a PWM pattern, of which modulation rate changes for one period of a sine wave, in a control circuit so as to minimize a motor current change in the inverter circuit for outputting AC power to a motor. CONSTITUTION:In the built-in memory of a control circuit 15, PWM patterns for one period obtained by changing the ratio (modulation rate) of a sine wave to a triangular wave for one period of the sine wave are combined with PWM patterns for one period obtained without changing the modulation rate and there are also stored PWM patterns obtained in view of the relation between an inverter frequency and the output voltage of an inverter circuit 13. The inverter circuit 13 is controlled by a PWM control signal 16 outputted from the control circuit 15. As a result, the change of a motor current flowing through the inverter circuit 13 can be made small. Thus, there is a low possibility that an overcurrent flows through the inverter circuit 13, and it is consequently possible to prevent the destruction of a power transistor in the inverter circuit 13.

Title: Magnetic body detector
Inventor: FUJIWARA KOICHI
IPC: G01R33/06
Filed: 1987-04-27
Abstract: PURPOSE:To facilitate automation of inspection while enabling handy and quick immunological measurement, by detecting turbulence of a magnetic flux generated as output difference signal of a plurality of magnetic body detection elements when a sample is inserted into a gap provided between a permanent magnet and a magnetic core. CONSTITUTION:A magnetic flux density on semiconductor magnetoresistance elements 2-1 and 2-2 of lines 6 of magnetic force leaving a permanent magnet 3 is equal when there is no sample 8 and it is different as being affected by a magnetic superfine particle in the sample 8 when it 8 exists. Therefore, if a zero balance is taken beforehand when no sample exists, a peak value of a signal waveform can be large while the spectrum width thereof can be small during the passage of the sample between magnetic body detectors with the presence of a core. On the other hand with the presence of the core, the peak value of the signal waveform is small and the width thereof is broad. This achieves a higher detection sensitivity along with higher resolutions. By a magnetic immunologic measurement, a fine magnetic pattern can be identified.
