Title: Lamp lighting device and exposure device using same
Inventor: SEKINE SHINJI
IPC: H05B37/02
Filed: 1990-09-29
Abstract: PURPOSE:To prevent lowering of a lamp life by installing a by-pass circuit to control pulse-like voltage which a lamp generates with counter electromotive force in parallel with the lamp. CONSTITUTION:When an AC power source 11 is turned on, a DC power source 10 rectifies AC output. A switching device 12 turns on and off to switch a rectifiedly smoothed DC voltage. Then, a generated square wave voltage is supplied to light up a lamp 15. As the lamp 15 has an inductance component, it intends to generate a spike-like over-voltage by counter electromotive force at a steep rise-time and a fall-time when the square wave voltage is imposed, but the energy of an inductance component is discharged by means of a by-pass circuit 16 to control generation of a spike-like voltage. It is thereby possible to prevent lowering of a lamp life and breakdown of a switching element.

Abstract: PURPOSE: To transfer a pattern onto a thin layer by causing laser fusion of a material to be patterned with laser irradiation in which a layer of a patterned thermal conductor is not connected with a thermal conductor. CONSTITUTION: A precision timing device includes an aluminum layer buried in an SiO2 , on which a composite Cr/Cu layer is vacuum-vaporized, and a patterned resist layer is disposed on an upper surface of the bracket Cr/Cu layer. Then, Au is electrically plated on the exposed Cr/Cu layer, and the resist is exfoliated and the whole of the substrate is subjected to ion milling. Then, the substrate is irradiated from a front surface thereof with a KrF laser, without a blanket or a pattern for fusing and removing the Cr/Cu layer. The Au is left behind undamaged. Hereby, a patterned layer is formed on a substrate without any pattern.

Inventor: WACHI SHIGEAKI
IPC: G11B7/09
Filed: 1989-10-06
Abstract: PURPOSE:To stably detect off-track without being affected by the difference of an optical disk and the deviation of focus by detecting the off-track from a relative level relationship between the reproducing outputs of pre-recorded areas in the optical disk. CONSTITUTION:Circuits 37-42 are provided to detect reproducing outputs SA and SC of code signals from the tracks under recording and reproducing outputs SB and SD of code signals from the tracks adjacent to the tracks under recording based on the address information of the tracks. Circuits 43-49 are provided to detect the off-track from the relative level relationship among the reproducing outputs SA, SB, SC and SD from the detection circuits. The relative level relationship among these reproducing outputs is calculated by a subtraction processing and the off-track is detected from the value of a subtraction output. Thus, by using the relative level relationship, the off-track is prevented from being erroneously detected by the difference of the optical disk or the focus error, etc.

Abstract: PURPOSE:To improve operability and to decrease the cost of an apparatus by using the relationship between the change in integrated value of absorbances stored in an associated memory and the change in blood state with respect to the time change in integrated value of the absorbances, and operating the change in blood state. CONSTITUTION:A light-source driving part 22 is controlled with a CPU 34 through an interface 32. Light sources 20a - 20c are sequentially lit. The lights having the wavelengths lambda1 - lambda3 from the light sources 20a - 20c are guided into a specimen 6 through a lightguide 24. The detected signal of a light receiving part 26 is received with the CPU 34 through an amplifier 28, an A/D converter 30 and the interface 32. In the CPU 34, the absorbances of the wavelengths lambda1 - lambda3 are sequentially measured and stored in a memory 36. When the peak of the pulsation of the blood is detected, the rate of the absorbance of the changing amount in the peak part is computed in two wavelengths or in three wavelengths. The relationship between the change in integrated value of the absorbances stored in the memory 36 and the change in blood state is used, and the saturation degree of oxygen is obtained. Thus, the operability is improved, and the cost of the apparatus can be decreased.
