Title: Multiple light signal generator
Inventor: IKUSHIMA HIROSHI
IPC: G02F1/03
Filed: 1982-03-02
Abstract: PURPOSE:To simplify the constitution of a multiple light signal generator in due consideration of a polarization state by using a linear polarizer which rotates around an optical path and a solid-state electrooptic element whose driving voltage is feely variable. CONSTITUTION:At an input part 1 formed of the linear polarizer which rotates around the optical path L, a polarization-axis direction is selected freely to obtain desired polarized incident light. Then, a control part 2 equipped with the solid-state electrooptic element 3 whose Kerr effect is controlled according to a control voltage from an element driving electric power source 4 imposes intensity modulation on said polarized light. Thus, the constitution of the multiple light signal generator which includes less constituent elements and takes the polarization state into consideration is simplified.

Title: Absolute position detecting device
Inventor: OKA YASUO
IPC: G01D5/34
Filed: 1993-02-23
Abstract: PURPOSE:To provide an absolute position detecting device which has an excellent antiseismic property and can be reduced in size and weight. CONSTITUTION:The rear surface 13 of an encoding plate 1 with a scale pattern on its front surface 12 is used as a reflecting surface and a light source 3 and image pickup element 2 for detecting absolute position are arranged in the same plane on the front surface 12. The absolute position of the plate 1 is detected by receiving light rays 1 transmitted through the surface 12 with the element 2. Since the plate 1 can be firmly fixed to a moving body 15, the plate 1 can withstand strong shocks and, since a fitting pedestal does not has a U- shape, but a plate-like shape, the rigidity of the pedestal 25 can be increased. As a result, the antiseismic property of this detecting device can be improved as a whole. Since the element 2 and light source 3 are arranged in the same plane, the same effect as that obtained when the light rays are made incident from the position of the virtual image of the light source 3 can be obtained and, therefore, the size and weight of the detecting device can be reduced, since the height of the detecting device itself can be reduced.

Abstract: PURPOSE:To simplify the structure and the assembly/adjustment of a dual mode type cylindrical cavity resonator by using an input and output coupling loops having a 90 deg. difference between their faces and a common coupling capacity element having a 45 deg. difference to each coupling loop. CONSTITUTION:This antenna sharing system consists of a cylindrical cavity resonator main body 1, an input (output) coupling loop 4 for H mode wave (frequency fH), an input (output) coupling loop 5 for V mode wave (frequency fV and fHnot equal to fV) and a common coupling capacity element 8. A 90 deg. difference is secured between a loop face where the loop 4 crosses a magnetic field and a loop face where the loop 5 crosses the magnetic field respectively. At the same time, a 45 deg. difference is secured between each loop face of both loops 4 and 5 and the element 8. An antenna feeder is connected to the element 8, and a transmitter or a receiver is connected to the loops 4 and 5. Thus it is possible to obtain an antenna sharing system for double waves.

Title: Jointing method for lead
Inventor: MAKINO YUTAKA
IPC: H01R43/02
Filed: 1989-02-14
Abstract: PURPOSE:To embody a reliable joint of high reliability with good productivity by heating a lead using a laser beam of high density under the condition wherein the lead is applied with pressure toward the electrode of a circuit board. CONSTITUTION:In connecting a lead 12 to a circuit board 1, a solder layer 13 is first formed on an electrode 11 on the circuit board 1. Then, the lead 12 is positioned at the focusing position of a laser beam 5 and a hollow tool 6 is lowered. The lead 12 is pressed with the tip of the tool 8 and a laser beam source 5 is operated. thereby focusing the laser beam 3 for irradiating the lead 12. Thereafter, the lead 12 is heated and the layer 13 is thereby fused, ensuring the jointing of the lead 12 to the electrode 11 via solder. In this case, when the laser beam 5 is increased in energy density it is possible to heat and fuse the solder layer 15 via the lead 12 in a short time. Furthermore, as the solder layer 13 is not directly heated with the laser beam 5, the solder is free from flying a round due to the rapid evaporation of flux and the joint of high reliability is obtained.

Title: Detector circuit for incomplete combustion
Inventor: SHINTAKU HIDETAKA
IPC: G01M15/10
Filed: 1984-02-23
Abstract: PURPOSE:To detect incomplete combustion securely by connecting load resistances including at least one variable resistance in series with respective plural photodetecting elements which photodetect light from combustion flames, and deciding on output of the photodetecting elements by comparison. CONSTITUTION:When an incomplete combustion state is entered, the photodetection wavelength of a color sensor becomes long, so an input voltage V2 to the 1st comparator 11 becomes higher than an input voltage V1 and the output of the 1st comparator 11 goes up to a level ''High'' to charge a capacitor C3 through resistances R3 and R4. Then, an input voltage V4 applied to the minus terminal of the 2nd comparator 12 increases on exponential function basis according to the time constant determined by resistances R3 and R4 and the capacitor C3 and then exceeds a reference voltage V3 applied to the plus input terminal a specific time later. Then, the output of the 2nd comparator 12 goes down to a level ''Low'' and a light emitting diode 13 turns on to warn the incomplete combustion state securely.

Title: Controlling method of drum level of evaporator
Inventor: FUKUMOTO KATSUTOSHI
IPC: F17C13/02
Filed: 1980-03-19
Abstract: PURPOSE:To accomplish stable control of the operation of an evaporator in its low-load operational range, by changing a setting value of a system for controlling the level of an evaporating drum automatically according to the amount of gas discharged from the drum. CONSTITUTION:When an evaporator is operated under a constant load within the range of 10-50T/H, output of a function operator 22 is set at 0mm. and the steam level is also kept stable at a value near 0mm.. In this state, if the load is increased, output of a regulator 10 is raised and that of a flow regulator 13 is also raised, so that the opening of a control valve 14 is increased. Therefore, lowering of the level in an evaporating drum 1 can be prevented. On the other hand, if the load is decreased, the opening of the control valve 14 is reduced, so that raising of the level in the drum 1 can be prevented. Therefore, the setting value of the level in the evaporating drum 1 is changed with the load level, so that it is enabled to accomplish stable control on the operation of the evaporator in its low-load operational range.

CONSTITUTION:Laser beams 11 formed by a laser oscillator 10 are refracted downwards with a right angle by a reflex mirror 12 and condensed by a condensing lens 13. The condensed beams 11 are then refracted again by a reflex mirror 15 before they converge into a focus, and applied in parallel to the beams 11 just after being discharge from the oscillator 10. Hence a holding means 16 is axially moved in response to the tooth part 2 of a worm, and the reflex mirror 15 is adjusted in a manner such that the tooth part 2 is accurately irradiated with the beams 11. When the radiating direction is determined, a holding tube 14 is tightened by metal fittings 17. After said adjustment, the tooth part 2 is irradiated with the beams 11 to perform the uniform heat treatment to harden its contact surface with the laser.

Title: Method of crystal growth
Inventor: SAKAMOTO KUNIHIRO
IPC: H01L21/205
Filed: 1993-01-29
Abstract: PURPOSE:To form a lightly doped crystalline layer with a good heterojunction by forming a bismuth-absorbing layer on a single-crystal silicon substrate, and supplying a source gas over the substrate to grow single-crystal film under the bismuth-absorbing layer. CONSTITUTION:A bismuth-absorbing layer 8 is formed on a silicon substrate 4, and germanium is supplied. The germanium enters under the bismuth- absorbing layer 8, but it is prevented from diffusing. As a result, the three- dimensional growth of germanium is prevented and thus a flat germanium layer 9 is formed on the substrate 4. Silicon is supplied so that it may enter under the bismuth-absorbing layer 8. This prevents the germanium from depositing on the surface, resulting in a good heterojunction. After bismuth is removed, silicon is further supplied to form a flat silicon layer of good crystallinity. According to this method, it is possible to form a lightly doped crystalline layer with a good heterojunction.
