Title: Beam detector
Inventor: MIURA KUNIHIKO
IPC: G02B26/10
Filed: 1984-05-07
Abstract: PURPOSE:To perform accurate beam detection even when the parallelism of end surfaces of a photodetecting element is inferior by providing a light shield mask in front of an optical path of beam incidence on the photodetecting element. CONSTITUTION:The mask 412 which cuts off a laser beam 413 is fitted to the photodetection surface of the photodetecting element 410 to prevent an output waveform from being split on an end surface during the passing of the beam. Then, the mask 412 has a rectangular window at the end surface part of the photodetecting element 410 and where there is no lead-out component for an electrode line 411, and the laser beam 413 only when passing through this rectangular window part strikes the photodetecting element 410. Consequently, the precision, specially, parallelism of the window part of the mask is improved, so an input waveform to a comparator contains no noise as shown by an input waveform 2.

Filed: 1978-07-27
Abstract: PURPOSE:To make it difficult to receive an external magnetic field by detecting the voltage, which is induced in the coil of a motor, thereby to control the drive current of the motor. CONSTITUTION:A drive circuit and an amplifying unit are composed of P- MOSFETs 21 and 22, N-MOSFETs 23 to 26, detecting resistors 28 and 29 and a motor 20. During the non-driven operation of the motor 20, the closed loop of the motor 20 and the FEDs 23 and 24 and the closed loop of the motor 20, the resistor 29 and the FETs 26 and 23 are alternately switched to amplify the signals resulting from an external magnetic field. At this time, the voltage induced in the coil of the motor 20 by the external magnetic field is short-circuited by the closed loop of the FETs 23 and 24 so that it is converted into a relatively high current. Then, at the resistor 29, there is generated instantly a high voltage in the resistor 29, and stability is subsequently attained under a steady condition. As a result, the motor 20 is controlled by the voltage coming from the resistor 29.

Title: Can body connecting pipe device
Inventor: TOMITA HIROSHI
IPC: F17D1/18
Filed: 1995-03-27
Abstract: PURPOSE: To appropriately heat fluid flowing in an inside to prevent the occcurrence of clogging, even in a place where heating and heat insulation, from a pipe outer part side by a connecting pipe to the can body, are difficult, by internally inserting a heater, actually extending to an inlet to the shell of the connecting pipe, into it. CONSTITUTION: By a heater 7 internally inserted into a connecting pipe, since fluid flowing in the inside of the connecting pipe, or mixed fluid, of the fluid and the other fluid, are directly heated, and the heater 7 is extendedly provided to an inlet part 1b to the shell of the connecting pipe, heating is made directly over the inlet 1b. Because of direct heating from an in-pipe part, the thermally best efficient heating can be effectively made so as to inhibit utterly the hardening of the fluid, and moreover, this effective heating can be made to the inlet part 1b to the can body. Consequently, even in the can body and the connecting part where heating and heat insulation from outside are difficult, clogging, in the inlet part to the can body or in the vicinity of the inlet part, conventionally cited as a problem, is unoccurring.

IPC: H04L27/22
Filed: 1988-04-13
Abstract: PURPOSE:To prevent reception data demodulation failure due to antenna switching by stopping antenna switching control using a diversity control part, and connecting a receiver fixedly to the antenna of a good receiving state when the receiving state becomes faulty. CONSTITUTION:In the case of the antennal control, a microcomputer 19 counts the number of times of antenna switching in prescribed time by a signal from a terminal 24, and when it exceeds a prescribed value, it decides it to be C/N deterioration, and stops the antenna switching control using the diversity control part 21. Namely, the terminal 25 is made to be a low level, and switches 22, 23 are turned off. Then, as for the selection of antennas 11, 12 at this time, the terminal 26 is made to be a high level or the low level so as to connect the antenna which is connected longer to a synthesizer 13 during the counting of the number of times of antenna switching, that is, the antenna of the good receiving state to the synthesizer 13 fixedly. Thus, since the diversity control is made to be an invalid state and the receiver is connected fixedly to the antenna of one side when the receiving state becomes faulty, the demodulation failure due to the antenna switching can be prevented.

Title: Instantaneous frame synchronizing system
Inventor: KANEKO YOSHIAKI
IPC: H04L7/08
Filed: 1987-04-15
Abstract: PURPOSE:To prevent a transmitted voice data from being interrupted even in generating synchronizing step-out to be caused through tentative interruption by fading or the like by inputting 2a pieces of data strings shifted by one bit each before and after a prescribed position individually to a synchronization protection correction circuit. CONSTITUTION:When input data Data In are interrupted due to fading or the like for three frames only and the synchronizing step-out takes place, a 2nd deciding circuit 8 of the synchronization protection correction circuit 30 reads individually data strings D-2, D-1, D+1, D+2 from n-bit registers 11, 12, 14, 15 of a register 1 and compares a unique word UW0 of a prescribed pattern and finds out a register outputting a data string coincident with a prescribed unique word UW0. When the read data string D+2 from the register 15 is coincident with the prescribed unique word UW0, the count of a forward protection counter 5 is decrement into a value 2 less than the specified value 3. Thus, a forward output outputs NO. A backward protection counter 4 holds the preceding count. Thus, when the received data is inputted again, the frame synchronization is established immediately.
