IPC: B41J29/377
Filed: 1990-04-19
Abstract: PURPOSE:To present a safe printing head by providing a holding part on a head cover of a printing head to hold the printing head. CONSTITUTION:A place to grip a printing head, a holding part 18a, is made to be a head cover shape. On a head cover 18 of a printing head, holding parts 18a are provided at two spots on the upper parts of both side surfaces of the printing head cover so that a user can easily hold the printing head. On the holding parts 18a, washboard type unevenness is provided so that they will not be slippery when gripped. Also, by making the inside of the holding parts 18a hollow, the temperature of the holding parts 18a can be kept lower than that of the surface of the head cover 18. By this method, spots to be held for the printing head can be clearly shown, and since the printing head has an easily grippable shape, the other parts are not touched, and safety can be improved.

Abstract: PURPOSE:To monitor projection-side luminous flux securely by detecting laser diodes put in multiple constitution by a photodetectors composed of plural photodetecting elements through a lens. CONSTITUTION:The quantities of pieces LMA and LMB of monitor-side luminous flux of two laser diodes 2A and 2B which are photodetected by photodetecting elements 4A and 4B are converted photoelectrically into electric signals having levels corresponding to their quantities of photodetection, and they are inputted to and amplified by amplifiers 5A and 5B. Those signals amplified by the amplifiers 5A and 5B are applied to one-terminal sides of comparators 7A and 7B through LPFs 6A and 6B respectively. A reference voltage VR for reading and a reference voltage VW for writing are applied to the other-terminal sides of the comparators 7A and 7B and the amplified signals are compared with the reference voltages VR and VW and their variation components are applied to, for example, control terminals of LD driving circuits 8A and 8B. Thus, currents supplied to the laser diodes 2A and 2B are controlled with the voltages applied to the control terminals.

Title: Speed sensor unit
Inventor: NAGAOKA TAKAFUMI
IPC: B65G43/00
Filed: 1989-04-25
Abstract: PURPOSE:To securely detect a sensor becoming abnormal and to prevent a carriage from traveling abnormally by providing a circuit which sends out an abnormality detection signal when the difference in the number of pulses between 1st and 2nd sensors becomes larger than a set value. CONSTITUTION:An abnormality detection circuit for the sensors consists of waveform shaping circuits 20P, 20A, and 20B, gate circuits 21A and 21B, an up/down counter 22, a comparing circuit 23, a setter 24, a flip-flop 25, etc. Then is dust sticks on the photodetection surface of the photodetecting element of, for example, a B-phase sensor to disable photodetection, the counted value of the counter 22 is based upon only pulses of an A-phase signal Sa, so Y>=Y0 (set value) and the output of the comparing circuit 23 varies to an L level to raise the Q output of the FF 25 to an H level, thereby generating the abnormality detection signal. At the same time, the Q output of the FF 25 falls to the L level, so the gates of output gate circuits 26A and 26B are closed to inhibit the A-phase signal SA and B-phase signal SB from being sent out to an F/V converter. Consequently, the carriage is prevented from traveling abnormally.

Abstract: PURPOSE:To process a discontinuously placed data group as one file by including related information of the data group in management information including the entry point of the data group of each file to link related information itself. CONSTITUTION:At the time of adding data A' to data of a file A, data A' is written after data of the last file C already written in a data area. The file data management sector of data A' is written after the file C, and the pointer to the file management sector of data A' is written in a related information column. At the time of reading out the file A, the file management sector of data A' is searched by the pointer in the related information column to read out data A' after that A is read out by the file management sector of data A. Thus, data are processed as one file though their file management sectors discontinuously exist.

Abstract: PURPOSE:To obtain a bonding pad enabling execution of bonding at low cost and with especially high reliability by forming a conductor thin film in a specified thickness and in a linear pattern containing three points not being located on a straight line, within an IC chip mounting region on an insulative substrate. CONSTITUTION:A die-bonding pad 11 so formed as to contain three points p1 to p3 not being located on a straight line at least and also made up of a convolution-shaped gold Au thin film 10mum thick is formed within an IC chip mounting region on an insulative substrate 1. When an IC chip 4 is mounted on a bonding agent 3 and pressed from above, a part of the bonding agent 3 is forced out into a part wherein the die-bonding pad is not formed. When the bonding agent 3 is cured, excellent continuity is obtained between the die- bonding pad 11 and the IC chip 4, while the die shear strength of the IC chip 4 in relation to the insulative substrate 1 is prevented from lowering. By this method, the die-bonding pad enabling efficient and low-cost execution of bonding of high reliability can be obtained.
