Title: Dryetching method
Inventor: NAGAYAMA TETSUJI
IPC: H01L21/302
Filed: 1991-07-09
Abstract: PURPOSE:To materialize high selectivity and low damage without using fluorocarbon gas, in the dry etching of an SiO2 material layer. CONSTITUTION:An insulating SiO2 interlayer film 3 is etched using S2F2/CO mixed gas. As a removal process of the O atoms of SiO2, the two processes of the creation of SOx by S dissociated from S2F2 and the creation of CO2 by CO compete with each other, but the side of C-O coupling is more stable in energy sense than S-O coupling, so the latter process is superior. As a result, as compared with the case of using S2F2 singly, the accumulation of S is further accelerated, and high anisotropy, and high selectivity to base, and low damageability are achieved by the formation of a sidewall protective film 5 and an S stacked film 6. Furthermore, since CO itself is not it does not depositing bring about the pollution by carbon polymer on a wafer.

Title: Retractable head lamp controller
Inventor: YAGI SOUICHI
IPC: B60Q1/05
Filed: 1983-10-17
Abstract: PURPOSE:To attain the pashing operation with ease by raising a head lamp through the pashing switch operated with the head lamp stored so as to project for-drive beam for a specified period and then return the head lamp into the stored state. CONSTITUTION:When a pashing switch PSW is turned on with a lighting switch LSW off and a head lamp 1 stored, a capacitor C1 charged quickly. After the pashing switch is turned off, the charged voltage turns a driving motor M in the normal direction so as to raise the head lamp 1. A rotary contact piece is, at the same time, turned to a stop apart from a fixed contact piece 15a. In this state, a stand detecting switch SSW is turned on and a for-drive beam is projected from the head lamp via a relay RL3. Simultaneously, a transistor Q2 is turned on and the capacitor C1 is discharged electrically through a resistance R1. After the specified time passed, from the discharge, the transistor Q3 is turned off to light off the lamp and the relay RL1 is also turned off to reverse the motor M so as to store the head lamp. With such operating process, the pashing operation may be performed easily.

Afterwards, a photograph after being taken is copied in the reduced size, and a difference caused when being photographed is corrected so that a metallic piece marker of the real body being photographed and a marker on the photograph coincide with each other. Afterwards, a corrected copy image is transferred to a transparent OHP sheet, and it is stuck on a heater, and a heating resistor existing position is confirmed, and a position of perforating work is designated.

An actual transaction price is sampled on a transaction market, and an actual correlation function is generated from the sampled transaction price. The correlation function is matched with each theoretical model to select the most adaptive theoretical model. The indexes of both price flexibility and market unsteadiness of the selected theoretical model are identified as the ones on the actual transaction market.

Title: Magneto-optical disk memory medium
Inventor: FUKUNISHI SHUZO
IPC: G11B11/105
Filed: 1986-08-22
Abstract: PURPOSE:To obtain a disk medium having a high signal to noise ratio at a low cost by forming a transparent adhesive layer on a magneto-optical film and a transparent flat plate disk layer on the uppermost layer, and projecting a focused laser to the medium from the transparent flat plate disk side, thereby making recording, reproducing and erasing. CONSTITUTION:This medium has the transparent adhesive layer 5 on the magneto-optical film and the transparent flat plate disk layer 6 on the uppermost layer. The focused layer beam for recording, reproducing and erasing information is projected to the medium from the flat disk substrate 6 side. Double refractions, therefore, may be of any values regardless of the optical quality of the substrate 1. It is important that the flat disk substrate 6 be of optically high quality, but since this substrate does not require grooves, PC or PMMA manufactured by a casting method is usable for the substrate. Such materials are inexpensive and of optically high quality. A flat glass substrate is applied as well.
