Title: Detector for sparking state in ignition action of combustion equipment
Inventor: KUWABARA SHIGERU
IPC: F02P17/12
Filed: 1987-12-01
Abstract: PURPOSE:To make a sparking state in each ignition action accurately graspable by generating such voltage that corresponds to respective states of nondischarge, nonspark discharge and primary side no-voltage in an ignition transformer. CONSTITUTION:In a normal spark state, a nondischarge state due to spark gap distance excessiveness and a nonspark discharge state due to spark gap excessiveness, conditions of voltage and its current in a high-tension cord are different respectively. Accordingly, these conditions are detected in an electromagnetic induction method by a spark state detecting means 5 and discriminated by a discriminating means 8. In addition, the presence of primary side voltage in an ignition transformer 1 is detected by a primary side voltage detecting means 7, and discriminated by the discriminating means 8 as well. Then, according to discriminating output from the discriminating means 8, a different voltage is generated by a voltage generating means 9. Moreover, an output voltage out of the voltage generating means 9 is always recorded in advance by a proper recording means 10 during operation of combustion equipment 2. A spark state is thus accurately graspable from the recorded voltage.

IPC: H01L21/331
Filed: 1988-12-02
Abstract: PURPOSE:To accelerate the operational rate by a method wherein the second conductivity type silicon epitaxial layer is selectively epitaxial-deposited in the lateral direction from the edge of the second insulating film. CONSTITUTION:Resorting to the manufacturing process of bipolar transistors, the resistance of a base extraction electrode can be lowered by forming a thin silicon epitaxial layer 13 to form a base layer and exposing the base extraction electrode as well as depositing another thick silicon epitaxial layer 15. Furthermore, the silicon epitaxial layer 15 is deposited in the lateral direction as if covering the peripheral surface of a nitride film 14 so that the fine emitter region 18 hardly formed by the lithography may be formed in selfalignment with the opening width thereof controlled in excellent reproducibility. Through these procedures, the base resistance can be lowered even in the thin base layer with the emitter region miniaturized, thereby enabling the operational rate to be accelerated.

Title: Information processor
Inventor: YONEDA KIYOSHI
IPC: G06F11/28
Filed: 1988-12-02
Abstract: PURPOSE:To grasp the flow of a program from the executing history of the program by outputting the branch generating status, the branch origin address, and the branch destination address to a trace device at occurrence of the program branch. CONSTITUTION:A circuit 7 is connected to a CPU 1 in an information processor 6 via a signal line 12 which secures the branch generating status for output of the branch generating status, the branch origin address, and the branch destination address. When the branch generating status is inputted from the CPU 1 via the line 12 at occurrence of the program branch, the circuit 7 outputs the branch generating status, the branch origin address, and the branch destination address to a trace device 3 to record them there. Thus it is possible to know a specific time point when a specific branch occurred in the execution history of a program based on the trace data on the device 3. Then the flow of the program can be grasped even though a single pre-reading instruction includes >=2 branch instructions given to the same address and thereafter the branch occurs.

Title: Optical pickup device
Inventor: HONMA OSAMU
IPC: G11B7/135
Filed: 1988-12-01
Abstract: PURPOSE:To correct an astigmatic aberration in the radiation light of a semiconductor laser and to obtain a stable tracking servo characteristic by making diffraction grating unequal at intervals. CONSTITUTION:The radiation light 4 from the semiconductor laser 1 is divided into three by the diffraction lattice 2. Since the intervals (d) of the diffraction grating 2 are unequal at that time, the diffraction angles of a + primary light and a - primary light differ by the incident position of the radiation light 4, and the astigmatic aberration is generated. Thus, the astigmatic aberration of the radiation light 4 in the semiconductor laser 1 is corrected. Consequently, the focusing dislocation characteristic of a tracking error signal comes to a considerably high gain. Thus, the tracking error signal 13 having small fluctuation with respect to focusing dislocation can be obtained.

Title: Garbage disposal equipment
Inventor: KAGAMI YOZO
IPC: F26B9/06
Filed: 1994-12-08
Abstract: PURPOSE: To improve the efficiency of deodorization by a construction wherein a guide part leading a dry distillation gas to a heating source side is provided between an outlet part of a drying vessel to a passage for circulation and the heating source. CONSTITUTION: Air heated by a gas burner 3a is circulated forcibly through a circulation system by a fan F. Garbage is thereby dried. Water vapor and components of offensive smell are produced from the garbage by drying and a dry distillation gas containing them flows into a passage 2 for circulation from an outlet part 16. The components of the offensive smell in the dry distillation gas are combusted by the gas burner 3a and deodorized on the occasion when this dry distillation gas passes through the passage 2 for circulation. Since a guide tube 4a continues to the outlet part 16 and the downstream end part of the guide tube 4a faces the upstream end part of the gas burner 3a, the dry distillation gas flows on the gas burner 3a side on the occasion, while external air flows on the drying vessel 1 side.  Accordingly, the components of the offensive smell in the dry distillation gas tend to come into contact with the gas burner 3a and, therefore, a combustion deodorization effect is thereby improved.

Filed: 1994-12-08
Abstract: PURPOSE: To provide a compact and efficient image projection system. CONSTITUTION: A projection beam 11 supplied by a projector 3 is made incident on a beam splitter 7 assuming the form of a cholestric filter. The cholestric filter 7 reflects circularly polarized light radiation, which has a wavelength corresponding to the pitch of molecular helixes and has the direction of rotation corresponding to the direction of molecular helixes, to a reflector 9. Since the circular direction of polarized light reflected by the cholestric filter 7 is inverted by the reflector 9, this inverted beam 15 passes the cholestric filter 7 to reach a projection screen 5.

Title: Control system for optical modulating circuit
Inventor: NISHIO MAKOTO
IPC: H04B10/291
Filed: 1987-12-01
Abstract: PURPOSE:To obtain output modulated light which is invariably in phase with an input light signal by detecting a low-frequency discrimination signal from the output of a wavelength filter and controlling the wavelength filter with the maximum value of its amplitude. CONSTITUTION:Both 1st light 1 to be modulated and 2nd light 2 to be modulated are modulated with the discrimination signal of lower frequency than the input light signal has and then inputted to the wavelength filter 100, and the low-frequency discrimination signal is detected from the modulated light outputted by the wavelength filter 100 to control the wavelength filter 100 so that the amplitude is maximum. Therefore, even if low-level input light signals appear more than high-level signals according to the kind of the signal or a mark rate, the amplitude of the low-frequency discrimination signal is maximum only when the selected wavelength of the wavelength filter at the time of the incidence of the high-level input light signal is equal to the wavelength of the 1st light 1 to be modulated, so that the selected wavelength of the wavelength filter at the time of the incidence of the high-level input light signal is invariably equal to the wavelength of the 1st light to be modulated. Consequently, the modulated light which is in phase with the input light signal is obtained at all times.
