Abstract: PURPOSE:To efficiently produce a sintered magnet alloy by using wax having a low softening point as a binder and executing injection molding under specific conditions at the time of kneading magnetic alloy powder contg. Y or rare earth elements with the binder and subjecting the mixture to injection molding. CONSTITUTION:The paraffin base wax having <=120 deg.C softening temp. is used as the binder and the binder is added to the powder of the magnetic alloy contg. Y or rare earth elements such as Sm and Nd, the mixture is heated and kneaded. The kneaded matter is packed into a metallic mold for injection molding kept at <=35 deg.C and is injection-molded to an irregular shape in a magnetic field. The molding is in succession heated at 2-10 deg.C/min heating up temp. up to, for example, 250 deg.C in an Ar atmosphere or vacuum of <=20Torr pressure to remove the binder incorporated therein; thereafter, the molding is sintered at about 1190 deg.C.

Abstract: PURPOSE:To increase gate breakdown pressure resistance and current driving capability of a transister by a method wherein a source-side diffusion layer is also formed under an element dielectric isolation film, and a gate electrode overlaps with at least the source only on an element separation insulating film, in an electrostatic breakdown protective element by a transistor of MOS type in which an element dielectric isolation film is used for a gate insulating film. CONSTITUTION:An electrostatic breakdown protective element F3 of a transistor of MOS type in which an element dielectric isolation film 7 is used for a gate insulating film comprises a P-type Si substrate 3, drains 1, 4 formed by using an N--well opposite in conductivity type to the P-type Si substrate, sources 2, 5 formed by using an N--well similar to that described above, a gate electrode 6 of polycrystalline Si, and a LOCOS film 7 which is a gate insulating film. The sources 2, 5 and the drains 1, 4 overlap with the gate electrode 6 under the LOCOS film 7. Furthermore, since the gate 6 and the drains 1, 4 are electrically connected to terminal D, and the sources 2, 5 are electrically connected to ground E, if a positive static charges are applied to the terminal, the gate voltage increases, causing the transistor to be turned on and causing static charges to escape to the ground.

Title: Optoelectric transducer with multilayered structure
Inventor: AIGA MASAO
IPC: H01L31/04
Filed: 1986-08-04
Abstract: PURPOSE:To prevent reflection loss to enable light to reach the lowest layer for higher optical efficiency by a method wherein the refractive indeces of semiconductor layers are so set that they are higher as the distance from the side of incidence of light increases. CONSTITUTION:Refractive indeces are set at 3.8 for an n-type a-Si:H layer 5, 4.0 for a p-type muC-SiGe:H layer 4a, and 4.2 for an i-type a-SiGe:H layer 3, gradually higher as the distance from the side of incidence of light increases. With the layers being designed as such, a light beam landing on a side provided with a transparent conductive film 8 is not reflected by semiconductor layers but are absorbed by them, which allows the beam to arrive at the lowest layer. This eliminates optical loss, realizing an enhanced efficiency.

Title: Engine ignition timing control device
Inventor: MIURA NOBUO
IPC: F02P5/15
Filed: 1982-10-20
Abstract: PURPOSE:To obtain a satisfactory ignition timing characteristic over a whole engine speed range, by changing the ignition timing along a trapezoidal curve in accordance with changes in engine speed. CONSTITUTION:A chop signal generating circuit II issues a chop-like voltage in synchronism with a timing pulse from a pulser coil 20. Between positive and negative timing pulses generated from the pulser coil 20 in the above-mentioned circuit II, a saw-like waveform voltage having an inclined angle larger than that of the rising part of the chop-like voltage, is generated from a saw-like wave generating circuit III. Further, a comparator circuit IV compares the output voltage of the circuit II with the output voltage of the circuit III, and issues a turning-on signal when the difference between both outputs becomes zero. Due to this turning-on signal, a trigger signal generating section V triggers the gate of a thyristor 13 for ignition. With this arrangement, the ignition timing may be changed along a trapezoidal curve in accordance with changes in engine speed, thereby a satisfactory ignition characteristic may be obtained over a whole engine speed range.

Abstract: PURPOSE:To prevent mis-processing, by reading the content of counter repetitively and making processing when the content of read-in is coincident two times consecutively. CONSTITUTION:Address signals A1-A16 are outputted from a processor 1 with a counter read instruction, and when a read/write R/W signal is at 1, a stobe signal STB is at 1 when it is equal to the address signal set at a set section 4, and the contents Q1-Q8 of a counter 3 are read. The processor 1 stores data D1-D8 to a memory 2 or an internal buffer memory, the counter read instruction is executed again, the data which is read in is compared with the preceding data. When both the data are coincident, the data is processed as correct data, and if not coincident, a new data is stored repetitively, until they are coincident.  Thus, after the content of the counter 3 is confirmed, the processing is made, allowing to prevent mis-processing.
