Title: Injection system for distribution line carrier signal synchronously
Inventor: SATO HIROO
IPC: H04B3/54
Filed: 1988-12-16
Abstract: PURPOSE:To reduce interference at a reception point due to a phase difference in a carrier signal by oscillating a carrier signal modulated in response to a command signal from a central equipment distributing and sending its carrier signal to plural substation equipments and oscillating a carrier signal in common to each substation equipment from the central equipment. CONSTITUTION:A command signal A applying monitor and control is sent by the operation of an operation panel 12 of a central equipment 1. Then a pulse code generating circuit 13 generates a modulation signal C and the signal is fed to a 3 phase low frequency oscillation circuit 14. A 3 phase low frequency signal from the 3 phase low frequency oscillation circuit 14 is modulated by the modulation signal C to be a 3 phase carrier signal B. An amplifier circuit 17 of a substation equipment 3 provided with each substation 2 relays and amplifies the said carrier signal B and injects the result to a corresponding phase in the three phases of the substation buses 7. Thus, the carrier signal is injected synchronously in each substation 2, then no phase difference exists in the injected carrier signal, then the interference of the carrier signal at the reception point is considerably reduced.

Title: Semiconductor device and manufacture thereof
Inventor: KIN SAIKOU
IPC: H01L21/60
Filed: 1994-12-21
Abstract: PURPOSE: To stably bring a conductive large which is formed on the upper part into contact on a semiconductor substrate by forming a contact, using a contact pad and a contact plug. CONSTITUTION: A third insulating film 16 is formed as a whole, the etching of the third insulating film 16 is carried out in an etching process using a source contact mask, and a contact hole in which a contact pad 12" is exposed is formed. A conductive wiring 17 is formed and connected with the contact pad 12". At the time of arraying the source contact mask, an alignment margin is sufficiently large to have the size of the contact pad so that a second conductive wiring 17 can be prevented from being short-circuited with another conductor, due to the etching of a lower first insulating film 10. Thus, a conductive layer formed at the upper part can be stably brought into contact on a semiconductor substrate, while the area of a semiconductor element is minimized.

Title: Data sink and method, and served medium
Inventor: FUNAMOTO KAZUHISA
IPC: H04L27/22
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To reduce a time required for decoding processing. SOLUTION: In the step S4, a control circuit executes a trace back according to a prescribed rule. In the step S5, the control circuit discriminates whether or not information of a trace destination is equal to information stored in a corresponding address of a trace cache. When it is discriminated that the information of the trace destination is equal to the information stored in the corresponding address of the trace cache, a step 7 is executed. When the trace back is continued after this, since the result is identical to a result of a preceding trace back stored in the trace cache, the control circuit stops the trace back in the step S7. The control circuit in the step S8 reads a value stored in a left end of the trace cache and accesses an address of a path memory corresponding to the value to provide an output of a value stored therein as decoded data.

IPC: F24F11/02
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To properly detect choking of a filter without using a special part, such as a sensor. SOLUTION: When the rotational speed of a fan motor 76 is set according to an air flow by a rotational speed setting part 130, a microcomputer 74 sets a step for a control signal based on the setting thereof. By the step for the control signal, PWM control of the fan motor is performed. Further, the microcomputer corrects the actual step through the operation of a step comparing correction part 132 based on the output of a generator 122 corresponding to the rotation of a fan motor and effects feedback control. In this case, the set step for the control signal is compared with the step for the actual control signal, and based on the comparison result, it is decided by a deciding part 134 whether the filter is clogged or not.
