Title: Production of quartz-base plane optical waveguide
Inventor: TANAKA KANJI
IPC: G02B6/13
Filed: 1998-08-14
Abstract: PROBLEM TO BE SOLVED: To provide a process for producing a quartz-base plane optical waveguide having lessened loss and noise. SOLUTION: The process for producing the quartz-base plane optical waveguide consists in depositing a lower clad film 2 and a first core film 3A having the refractive index higher than the refractive index thereof on the surface of a substrate 1. Part of the core film 3A is etched away down to the lower clad film 2 and a second core film 3B having the refractive index higher than the refractive index the lower clad film 2 is deposited on the surfaces of the remaining core film 3A and lower clad film 2. Further, at least the surface layer part of the core film 3B is polished away by using a silica slurry, by which the surfaces of the core film 3A and the core film 3B are made flush with each other. Part of the core film 3A and the core film 3B is then etched away from the core film 3A down to the lower clad film 2, by which a core ridge is formed.  An upper clad film 5 is thereafter formed on the core ridge and the lower clad film 2.

Filed: 1982-12-28
Abstract: PURPOSE:To improve the precision of the conversion of an angular speed of a vehicle to an angle by limiting the integration of the angular speed with time in respect to time to reduce the cumulative mixture of the error of an offset quantity. CONSTITUTION:An angular speed sensor 10 detects an angular speed omega in the advance direction of the vehicle, and the value of the offset signal from an offset operating circuit 60a is subtracted in a microcomputer 60 to attain a subtraction result omegar, and the subtraction result omegar is added to a partial integral value DELTAS to update it, and a set unit integral value A is determined in accordance with a characteristic curve L, which prescribes the relation between a preliminarily stored running speed Vs and the set unit integral value A, on a basis of the value of the running speed signal from a running speed calculating circuit 50. If DELTAS>=A is not true, the addition operation is not performed. If DELTAS>=A is true, an overall integral value S=S+DELTAS is generated as a digital angle signal.

Title: Print head protector
Inventor: NAGATOMO AKIRA
IPC: B41J29/38
Filed: 1986-09-30
Abstract: PURPOSE:To diminish malfunction, by providing a means for detecting the mount/dismount of a print font cartridge and a means for interrupting power supply to a print head on the basis of said detection. CONSTITUTION:SW1 is turned OFF when a font cartridge is inserted and turned ON when the font cartridge is removed. Normally since the font cartridge is inserted, the switch SW1 is turned OFF to turn the transistors Q2, Q1 ON so as to apply voltage from a print drive power source 1 onto a print head drive circuit 2'. When a print head drive signal is inputted to an input terminal 3, the print head drive circuit 2' functions to drive a print head element 2 so as to carry out printing. When the font cartridge is removed, the switch SW1 is turned ON so as to turn the transistors Q2, Q1 OFF. Consequently, voltage from the power source 1 is interrupted, whereby the drive circuit 2' does not function even if the print head drive signal is inputted to the drive signal input terminal 3.
