Abstract: PURPOSE:To obtain a frequency division signal whose duty cycle is 1/2 independently of the speed of a clock signal by eliminating gaps of a 1/2 frequency division signal obtained through the OR processing between a frequency division signal and a half width frequency division signal while superimposing a delay signal. CONSTITUTION:In giving a clock signal CLK to a frequency divider circuit 1, a frequency division signal P1 whose period is T0 and whose duty factor is 1/3 is outputted from a terminal Q of an FF11. A frequency division signal P2i whose phase is inverted at a phase difference of a clock period Tc with respect to a signal P1 is outputted from a terminal Qi of an FF12. The signal P1 becomes a delay signal PLd while receiving a delay time T1d by gates 23, 24. A gate 25 applies OR and NOT processing to the signal P2i and an inverted clock signal CLKi to output a half width frequency division signal P2h whose duty cycle is 1/6. A gate 22 applies OR processing to the signals P1, P1d and P2h to obtain an output PO, then the gap between the signals P1 and P2h is interpolated surely by the signal P1d.

Title: Alloy-free power semiconductor element and its manufacture
Inventor: WATANABE MASAHIDE
IPC: H01L29/74
Filed: 1994-03-08
Abstract: PURPOSE:To maintain a positive bevel angle, to prevent an applied protection film from drooping and to stabilize breakdown strength by forming a ring of an anti-etching film whose outer diameter is larger than an outer diameter of a semiconductor substrate in an outer circumferencial part of a main plane of a semiconductor substrate which forms a positive bevel angle to a bevel surface. CONSTITUTION:A semiconductor element is a GTO thyristor of a reverse- blocking type, for example, having both forward breakdown strength and reverse breakdown strength. A bevel has a SIGMA-shaped cross section for making both forward breakdown strength and reverse breakdown strength a positive bevel. Oxide film rings 4A are in both upper and lower main surfaces of a semiconductor substrate 1 and protect an outer circumferential end of a bevel 3. Thereby, an outer circumferencial end of a bevel of an alloy-free type power semiconductor element is not rounded and a positive bevel angle is thereby maintained, thus preventing an excessive protection film from flowing out. Since a protection film as a design value can be applied in this way, an alloy-free type power semiconductor element of stable breakdown strength can be realized.

Title: Vertical duplex head surface grinding machine
Inventor: SAITO AKIYOSHI
IPC: B24B7/17
Filed: 1987-02-19
Abstract: PURPOSE:To prevent the heat of grinding fluid from being transmitted to a machine body as well as to aim at improvement in accuracy of finishing, by making the grinding fluid to be fed to a wheel part pass through only the inside of a wheel guard, and discharging it to the outside from a grinding fluid discharge port at a lower end of the wheel guard. CONSTITUTION:The work held by a rotating carrier disc 15 is ground between two grinding wheels 7 and 8. On the other hand, grinding fluid is fed to a grinding part from a grinding supply passage 29 of a turning shaft 5, and it is discharged to the outside from a discharge port via a discharge pipe 18 after passing through only the inside of a wheel guard 12. Therefore, even if the wheel guard 12 itself is heated by heat of the grinding fluid, heating value of the grinding fluid is not almost transmitted to a machine body 1 because the wheel guard 12 is set up as separated from the machine body 1, supported by legs 21 and 22 via a heat insulating material 23, and a heat insulating plate 26 is set up in a gap with the machine body 1 whereby a convective air layer is cut off. Thus, thermal deformation in the machine body is not caused and accuracy of finishing in the work is favorably maintained, while cleaning of the residual grinding fluid after operation comes easy.

Title: Magnetic sensor
Inventor: ENDOU MICHIKO
IPC: G01R33/09
Filed: 1994-03-08
Abstract: PURPOSE:To obtain the magnetic sensor whose sensitivity can be made high in a very small magnetic field by a method wherein the direction of spontaneous magnetization is changed forcibly from an easy direction of magnetization to a hard direction of magnetization by properly combining the direction of the strain of a magnetic substance with the positive/the negative of the magnetization constant of the magnetic substance. CONSTITUTION:A meander shaped sensor pattern 21 which uses a ferromagnetic-metal thin film is formed on the surface of a substrate 22. When, e.g. an iron-nickel alloy is used for the ferromagnetic-metal thin film, an easy direction of magnetization in its strainless state is the lengthwise direction of the pattern, and a hard direction of magnetization is the short direction of the pattern. Then, since a magnetization constant is positive, the spontaneous magnetization of the sensor pattern 21 is directed to the hard direction of magnetization when a tensile stress is applied to the short direction of the sensor pattern 21, i.e., to the hard direction of magnetization. As a result, when a magnetic field Hex is applied to the lengthwise direction of the sensor pattern 21 in this state, the direction of magnetization is changed into the easy direction of magnetization. As a result, a change in magnetization in a very small magnetic field is made smooth, and the high sensitivity of the magnetic sensor can be achieved.
