Title: Cutting method and jig for thin film in production of mask protecting device
Inventor: FUJITA MINORU
IPC: G03F1/64
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To obtain a cutting method of a thin film without producing cutting chips which cause dust by adhering an org. thin film to one side face of a pellicle frame and cutting the excess film extending from the outer edge of the frame while coating the film with a coating soln. discharged from a jig which moves along the edge. SOLUTION: An org. thin film formed on a substrate is once attached to a temporary frame and then adhered to one side face of a pellicle frame. The excess thin film 3 extending from the outer edge of the frame is cut by using a jig 11. In this process, the jig 11 is moved along the edge while a coating material soln. 19 is discharged through a discharging port 12 so that cutting of the thin film 3 and coating of the cut face are performed at one time. Therefore, cutting chips are fixed with the coating material, which prevents dust due to dropping of chips. Since the cut face of the thin film 3 is not exposed, the production of cutting chips or dust from the cut face is prevented. Since cutting and coating are carried out at one time, the work efficiency and productivity are improved.

Title: Plasma etching method
Inventor: KOSHIO ATSUSHI
IPC: H01L21/302
Filed: 1989-05-24
Abstract: PURPOSE:To control a taper angle of an etching shape by performing etching by periodically repeatedly producing and interrupting rf discharge. CONSTITUTION:After a semiconductor substrate 4 is placed on a lower electrode 3, mixture gas such as SF6 and CCl4 is introduced into a chamber 1, and then rf power from a rf power supply 7 is applied across the electrodes 2 and 3 and switched on and off periodically. Once the rf power is interrupted after a plasma state formed, residence time of neutral molecules such as SF2, SFCl, SCl2 and the like in the chamber 1 is made longer to be about several times of seconds, while radicals have shorter residence time differing from the neutral molecules but exist at a state where the rf power is interrupted. Accordingly, discharge time can be controlled by the repeated production and interruption of the rf discharge. Hereby, a taper angle of an etching shape can be controlled.

IPC: H01L21/205
Filed: 1988-05-27
Abstract: PURPOSE:To reduce the transition width of the subject layer and to decrease the size of elements, by forming the subject layer on a substrate in a silane- based reactive gas atmosphere by a thermo-chemical evaporation using a specific gas as a cleaning gas, thereby suppressing the auto-doping phenomenon.

The above process is carried out in the presence of SiHnFm gas for cleaning the substrate. In the formula, n and m are positive integer excluding 0 and n+m is 4. The cleaning gas is decomposed even at a low temperature into silicon hydride and SiF4 in a mixture of a silane-based reactive gas, a cleaning gas and a carrier gas or a reducing gas. It is supposed that a free F atom is produced in the above decomposition process and an O atom in a natural oxide film existing on the Si substrate surface is eliminate from Si atom by the produced F atom. The cleaning of substrate can be carried out at a low temperature to achieve the reduction of the size of elements.

Title: Resin composition for optical information recording body
Inventor: KAMISAKA TOSHIO
IPC: G11B7/24
Filed: 1985-06-17
Abstract: PURPOSE:To stably mold specified polyvinyl acetal at a high temp. without causing an unfavorable phenomenon such as burning, decomposition, deterioration, foaming or coloring by adding an antioxidant to the polyvinyl acetal. CONSTITUTION:An antioxidant is added to polyvinyl acetal obtd. by modifying polyvinyl alcohol having 100-2,000 average degree of polymn. to >=60mol% degree of modification to acetal. The resulting polyvinyl acetal is easily molded by injection molding and gives a molded body having a low double refractive index and suitable for use as the base of an optical information recording body. When polyvinyl acetal has a lower degree of modification to acetal, it absorbs water at a high rate, elongates largely by water absorption and has inferior dimensional stability. When the degree of modification to acetal is increased, the rate of water absorption and the elongation by water absorption are reduced. A hindered phenol compound having >=250mol.wt. is suitable for use as the antioxidant.

Title: Multi spindle head gear beveling machine

IPC: B23F19/10
Filed: 1985-06-17
Abstract: PURPOSE:To reduce the time required for shifting the arrangement thus to improve the machining efficiency by providing beveling cutters conforming with the features of gear to be machined by same number with the gear on each cuter shaft of turret thereby beveling each gear thereafter deburring the gear at the opposite faces through deburring unit.

Title: Demodulator and receiver
Inventor: TAKAHASHI JUNICHI
IPC: H04B7/10
Filed: 1991-05-08
Abstract: PURPOSE:To provide a simply constituted demodulator that accurately separates and demodulates a signal obtained by modulating one carrier wave for angle and amplitude by two pieces of information and that is hardly affected by level variation of the input. CONSTITUTION:An input signal modulated for angle/amplitude is input in an AGC amplifying section 10, the output from the amplifying section 10 is input in an AGC amplifying section 20. The output from the AGC amplifying section 20 is demodulated for FM by a FM demodulating section 30 and at the same time is detected for AM by an AM wave detecting section 40. The wave detecting output from the AM wave detecting section 40 is used to carry out negative-feedback control of the AGC amplifying section 20. Further, this control signal is filtered by a BPF 60 to obtain the AM modulation component. Since a high speed negative-feedback loop is constituted by the AGC amplifying section 20 and the input to the demodulating means becomes constant regardless of level variation, the AM modulation component with a constant amplitude can be taken out, and the disturbance of angle modulation/demodulation by amplitude variation can be considerably reduced even when the amplitude limiter does not work sufficiently. Furthermore, the disturbance that frequency shift is converted for AM can be suppressed by the inclination of band characteristic of signal path, and the inclination is also effective for carrying out angle modulation/ demodulation and amplitude modulation/demodulation by using one IC.
