Filed: 1995-04-13
Abstract: PURPOSE: To provide a condensing element for optical fiber capable of improving a condensing efficiency and which is easily executed and has a simple constitution by providing the condensing element for a condensing at the detection end of an optical fiber. CONSTITUTION: A condensing element for optical fiber 11 has an unfolded sectorial rotary surface whose diameter becomes larger with the going of the reflection surface 24 of the surface of a core 12 from the front end part to the rear end part and the light beam made incident from the front end face is reflected at the boundary surface to be made incident on an optical fiber 1. Since the light beam is inclined to a direction approaching parallel beams by being reflected at the reflection surface 24 of the surface of the condensing element 11, even the incident light being out of the range of the maximum light receiving angle of the optical fiber 1, the inclinations of the reflected light in the optical fiber 1 are maintained in the range of a total reflection angle.  Thus, the range of the light receiving angle in which the optical fiber 1 can receive the light becomes large as compared with the case the condensing element 11 is not used, that is, the condensing element has an effect to that the maximum light receiving angle of the fiber 1 is made large.

Title: Initialization diagnosis and display circuit
Inventor: IDOKAWA ATSUSHI
IPC: G06F11/22
Filed: 1985-05-24
Abstract: PURPOSE:To indicate clearly initialization and diagnostic display in the initialization without providing any display element specially by providing a means which displays the initialization diagnostic state of a data processor on the same display element by changing its light emission state. CONSTITUTION:A light emitting diode 31 illuminates with brightness corresponding to the value of a current i2 in response to the input of an initialization signal (a) and turns off when the initialization and diagnosis of the processor are completed normally at timing T1. If the processor becomes abnormal at timing T2, timing T3 coincides with the T2 and the output of a display stop signal (b) is not at L, so the output (f) of a multivibrator 21 has width T3 and an FF 22 is set with the leading edge of the signal (f) which rises a pulse output from L to H, so that the output (d) of a driver 23 falls to L, thereby entering a driven state. A current i1 flowing through the light emitting diode 31 from the timing T3 varies from i2 to i2+i3 to allow the light emitting diode 31 to emit with larger brightness. Consequently, the abnormal state is displayed.

Abstract: PURPOSE:To solve problems such as increase of processes and decrease of PSG film thickness at the same time by using a spin-on-glass that contains phosphorus so as to diffuse it in a short time by lamp annealing. CONSTITUTION:A contact hole 102 is formed by etching in an interlayer phosphosilicate glass(PSG) film 101, and next a spin-on-glass film 203 is formed which is diluted by methanol which contains 5% silanol that contain 10% phosphorus by weight mole% to silicon. Next, to perform diffusion from phosphorus of the spin-on-glass film to a silicon substrate, lamp annealing is executed for 20 seconds at 1150 deg.C. And it is dipped in aqueous solution of hydrofluoric acid to water, 4 to 1, for 5 seconds so as to remove the spin-on-glass film 203 accumulated in the contact hole part and to form wiring. Hereby, in elevating integration degree of N-type MOS semiconductors, increase of processes is restrained, and since spin-on-glass high in phosphorus concentration has great etching grade to hydrofluoric acid aqueous solution, decrease in thickness of the PSG film can be prevented.
