Title: Method and device for deciding focus of laser beam
Inventor: RIYUUDEIGAA ROOTE
IPC: B23K26/02
Filed: 1990-09-10
Abstract: PURPOSE: To judge laser beam focus elements accurately with a simple configura tion by receiving reflection laser beams by a rotation-symmetrical reflector with a reflector having a sensor and judging a focus based on the output of received light at the time of required directional move of the reflector and the relative move of the sensor for the reflector. CONSTITUTION: Laser beams 2 from an opening 4 of a housing 3 are reflected from a reflection surface 6 of a relation-symmetrical reflector 5, become low- density laser beams, and enter a sensor 10 provided at a reflector 7. When the reflector 5 is moved in axial direction of the beams 2, a focusing surface is judged from the measurement value of the sensor 10. A position in side direction of a focus is judged by a move that is at right angle to it. Further, a focus diameter is judged by moving the sensor 10 relatively to the reflector 5. By using low-density laser beams, for example, the need for the high-speed rotation of optical parts is eliminated and the focus element of laser beams can be judged accurately.

Title: Maximum value detecting circuit
Inventor: OTSUKA MARIKO
IPC: H03M1/18
Filed: 1989-09-18
Abstract: PURPOSE:To enable direct detection of a maximum value from a digital signal by constructing a maximum value detecting circuit so that it can execute a digital processing, by connecting it directly with the same integrated circuit with a digital signal processing circuit and by detecting the maximum value thereby. CONSTITUTION:When it is assumed that n-bit data D' (expressed by a decimal number) inputted from an n-bit full adder 2 are latched in an n-bit latch 3, an output from inverters 4 numbering (n) is (2<n>-1)-D'. Now, when fresh data D come in a first input 2a of the full adder 2, the output from the inverters 4 is present in a second input 2b of the full adder 2 and the sum of the inputs to the full adder 2 turns to be (2<n>-1)-D'+D. Since the data from a first bit to an n-th bit are all 1 herein, a carry occurs in the full adder 2 when D>D'. When the fresh data are larger than the preceding data, in other words, the carry is outputted from the full adder 2 and the fresh data are latched. The data are compared sequentially in this way and the larger data are left behind.

Title: Electromagnetic relay
Inventor: INOUE SEIJI
IPC: H01H50/44
Filed: 1988-09-26
Abstract: PURPOSE:To lessen cumulative errors at the time of parts installation and to decide the locational relationship between major parts in high precision by welding a movable contact piece having a movable contact with a movable contact terminal fixed to a base, and fitting a stationary contact terminal having stationary contact into the base by pressure. CONSTITUTION:The locational relationship of stationary contacts 21a, 21b with movable contacts 19a, 19b can be determined by reference to a base 1, being not influenced by the assembly accuracy of an electric magnet block 4 to the base 1. The locational relationship of the magnetic pole surfaces 46a, 46b of a core 40 with magnetic pole parts 30a, 30b of a pole contact piece 30 can be determined by reference to a spool 42 of the electric magnet block 4, not being influenced by its installation accuracy to the base. Accordingly the cumulative errors due to parts installation are small, and dispersion of assembly accuracy is small from completed electromagnetic relay to relay to provide stabilized operating characteristics, which facilitates adjusting operation and reduces man-hours for works.

Title: Electronic tuning type receiver
Inventor: MASUDA ICHIRO
IPC: H04B1/18
Filed: 1990-09-11
Abstract: PURPOSE:To adjust the sensitivity of an electronic tuning type receiver without complicating the circuit constitution of the receiver by shifting the tuning frequency of a filter from the desired level by a fixed extent when a sensitivity reduction switch is operated and keeping the local frequency of a local oscillator at a level corresponding to the desired frequency. CONSTITUTION:When the tuning frequency fO of each of high frequency band pass filters BPFs3 and 5 is shifted from the desired frequency fR, both BPFs3 and 5 produce the loss to the frequency fR. In such conditions, the local frequency fL is kept at a level accordant with the frequency fR. Thus the obtained intermediate frequency if1 is strictly kept at a level corresponding to the frequency fR. Then the frequency fO of the frequency variable BPFs3 and 5 can be easily changed by a control part 8 and no addition of any circuit is required. Thus the sensitivity can be adjusted without complicating the circuit constitution for this electronic tuning type receiver using the frequency variable BPFs3 and 5.
