Title: Driving circuit of semiconductor laser
Inventor: YAMAGATA MATAZOU
IPC: H01S5/068
Filed: 1980-01-22
Abstract: PURPOSE:To obtain a stabilized photo-output by giving a temperature characteristic to a modulation current of the semiconductor laser by a method wherein a prescribed number of diodes are connected in series to a base of a transistor connected with the semiconductor laser, out of a pair of the transistors. CONSTITUTION:The diodes D1-D3 are connected in series between an emitter of the transistor TRQ1 and the base of the TRQ2 connected with the semiconductor laser LD. With the thus formed circuit, the variation of currents flowing through a resistor R3 with respect to the temperature depends on the number of the diodes connected in series with each other. Accordingly, the modulation current of the laser LD can be provided with the temperature characteristic by connecting the number of the diodes suitably selected fitting to the temperature changes of the laser LD. As a result, the stabilized photo-output can be obtained regardless of the temperature changes.

Title: System for measuring time width of logical wave form
Inventor: KOBAYASHI KATSUJI
IPC: G01R31/28
Filed: 1985-01-17
Abstract: PURPOSE:To increase a measuring speed while automating measurement, by successively comparing the logical value of each logical wave form at a sampling point with the normal logical value of each logical wave form at the point of time to be measured and calculating the time width of the logical wave form to be measured from the number of the sampling point where both logical values coincide. CONSTITUTION:When a main logical wave form is a normal one, the logical value at each measuring point is stored in a memory apparatus as the logical value at a normal measuring point. A drawing (a) shows a sampling logical value memory apparatus of a logical wave to be measured and N logical wave forms L1-LN are successively sampled at sampling points S1-SN and record in sampling number order. The measured logical values are at first compared with the logical value at a measuring point 1 in sampling number order. If the measured logical value coinciding with said logical value at the measuring point 1 appears, the sampling number at this time is recorded and this recording is formed as the measured result. By this method, the measurement of the time width between arbitrary change points of the logical wave form to be measured is enabled by subtraction between sampling numbers obtained from a memory means and a measuring speed can be increased and measurement can be automated.

Title: High-brightness discharge lamp
Inventor: WADA SEIGO
IPC: C09K11/06
Filed: 1987-01-14
Abstract: PURPOSE:To obtain a lamp which has the high lamp efficiency and good starting characteristic and is inexpensive by sealing a luminous material gasified at 400 deg.C or below into a luminous tube provided with discharge electrodes. CONSTITUTION:beta-diketone metal chelate sublimated at 400 deg.C or below is used as a luminous material sealed into a luminous tube 1 provided with discharge electrodes 2a, 2b. Hard glass inexpensive and easy for fabricating compared with quartz glass is used for the luminous tube 1. The rare gas sealed in the luminous tube 1 is discharged, and mercury is evaporated. Since the ionization potential of the evaporated mercury is lower than the ionization potential of the rare gas, the subsequent discharge becomes the mercury discharge performed mainly by mercury. The evaporation quantity of mercury is further increased, the lamp input power is further increased, and the arc temperature rises. As the arc temperature rises, thermal ionization also grows. Accordingly, since the operating temperature is low, the time to reach a normal lighting state is shortened, and the starting characteristic becomes good.

Title: Superconducting integrated circuit
Inventor: NUMATA HIDEAKI
IPC: H01P3/08
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To provide a superconducting integrated circuit which enables miniaturization and integration by increasing inductance per wiring unit length. SOLUTION: A superconducting integrated circuit has a structure provided with a soft magnetic material layer 13 which has a high permeability μ between interlayer insulating films 12 and 14. The structure enables the inductance per unit length of superconducting wiring 15 to be larger than that of the conventional circuit. Therefore, the total thickness T1 of the interlayer insulating films 12 and 14 and a soft magnetic material layer 13 is less than the thickness of the conventional interlayer insulating film. As a result, the width W1 of the superconducting wiring 15 is made narrower than that of the conventional circuit without being limited by a fringe factor KF, and the area occupied by the inductance is reduced.  Therefore, the superconducting integrated circuit can be miniaturized compared with the conventional one, and the miniaturization of the element can shorten the wiring length and increase the operation speed.

Abstract: PURPOSE:To enhance insulation between laminates and to suppress degradation of characteristics by providing a cutter section interlocked synchronously and intermittently with turning and dividing the phase with a predetermined angle at a part of circle for each turning laminate in a core for electric rotating machine to be laminated while turning. CONSTITUTION:An annularly formed stripe core material 21 is fed in through rotation of a winding shaft 1 and moved along a spiral guide groove in an annular guide 7. When the rotary phase amount reaches a set angle of 360+alpha, a pin 5 functions to push up a pawl 4 held on an index disc 2 and the pawl 4 hooks up a cutter 9 which thereby moves synchronously with the winding shaft in the circumferential direction. Upon start of movement of the cutter 9, a push down pin 12 pushes down a cutter 11 which then cuts off an annular core 21 placed between the cutters 9, 11. Thus cut off annular core 21 is guided by the spline type winding shaft on the inside and regulated by a guide wall on the outside and thereby the annular core 21 can be fit with a protrusion 24 without causing positional shift.
