Title: Ultraviolet rays irradiator
Inventor: IWASAKI BUNJI
IPC: B41F23/04
Filed: 1985-03-27
Abstract: PURPOSE:To regulate the amount of infrared rays to be irradiated and also of mercury spectra of visible rays region by not varying the amount of infrared rays to be irradiated onto irradiating faces by providing plural stages of filters having a reflector to reflect visible rays and infrared rays but to permit the permeation of ultraviolet rays and a transmitter for ultraviolet rays, visible rays, and infrared rays. CONSTITUTION:When a front filter 21 is moved in parallel and the reflector 25 of a rear filter 22 is matched with the reflector 25 of the filter 21 at a position in the vertical direction, the amounts of visible rays and infrared rays to be irradiated to irradiating faces are increased. When the filter 25 is moved in parallel and the reflector 25 of the filter 22 is matched with the transmitter 26 of the filter 21 at a position in the vertical direction, the amounts of infrared rays to be irradiated onto irradiating faces are decreased. By adjusting the lap width of the reflector 25 of the filter 21 to the reflector 25 of the filter 22, the amounts of visible rays and infrared rays to irradiating faces are regulated, whereby accelerating the hardening speeds by ultraviolet rays and protecting the base material having small heat resistance.

Title: Frequency converting circuit
Inventor: IMAFUKU KAZUO
IPC: H04N5/44
Filed: 1983-04-08
Abstract: PURPOSE:To remove spurious disturbance to be generated over a specific channel by interposing the 1st filter between the 1st and the 2nd mixer circuits and the 2nd filter between the 2nd mixer circuit and a fixed oscillator. CONSTITUTION:A block 8 removes a local oscillation frequency component sent from a local oscillator 3 through the mixer of a block 2. When low-pass filters of blocks 8 and 9 and a trap circuit increase in loss, the total NF of the system deteriorates, so the degree of attenuation is hardly set large. For this purpose, a low-pass filter or track circuit for attenuating the local oscillation frequency is inserted as a block 10 behind an IF amplifier which exerts less influence upon the total NF of the system to set the degree of attenuation large enough.

IPC: H01S5/00
Filed: 1986-03-20
Abstract: PURPOSE:To sufficiently suppress leakage current that does not pass an active layer and obtain a laser with a low threshold, a high efficiency and a large output by forming a high resistance layer below the sides of the active layer. CONSTITUTION:A high resistance InP layer 2 is grown on a first conductivity type semiconductor, for example, an N<+>-InP substrate 1. A stripe mask 3 made of SiO2 is formed thereon and the high resistance layer of a light emitting portion forming region is partially removed by etching. Then, after the SiO2 mask 3 is removed, the first conductivity type N-InP layer 4 is grown flat so as to embed the whole high resistance layer and further an InGaAsP active layer 5 and a second conductivity type P-InP layer 6 are continuously grown. The SiO2 stripe mask is formed above a portion wherein the high resistance layer is absent and an etching is applied in a mesa configuration until the high resistance layer is reached. Then, both sides of the mesa thus formed are embedded with an N-type InP layer 8 and further, after the SiO2 mask is removed, a P-type InP layer 9 is grown so that an upper surface becomes flat. Thus, a laser with a low threshold, a high efficiency and a large output power is obtained.

IPC: G01D5/245
Filed: 1989-03-15
Abstract: PURPOSE:To obtain an encoder which achieves higher interpolation resolutions with a simple construction without raising a clock frequency by modulating an output signal of a detector with a phase modulator. CONSTITUTION:A phase signal phi varying in phase according to an angle of rotation of a code plate and a reference signal phir are outputted from a detector 1 and a phase of the phase signal phi is counted by a clock of a counter 21 with respect to the reference signal phir. With a local transmitter 4, a modulation signal M1 and a modulation start signal M2 are outputted and the phase signal phiis modulated in phase with a phase modulator 3 to obtain a modulation output phim. The counter 21 performs a counting using the reference signal phir as start signal and the modulation output phim as stop signal to obtain an output of a medium order bit. Moreover, a counter 22 performs a counting using the phase signal phi as clock signal, the modulation start signal M2 as start signal and an output C of a digital comparator 5 as stop signal to obtain an output of a low order bit. Thus, higher interpolation resolutions are achieved by modulating an output signal of the detector 1 with a phase modulator 3.
