Abstract: PURPOSE:To obtain the titled device having metallic wiring of high reliability by a method wherein a wiring is formed after the stepwise difference due to a contact hole is substantially eliminated by filling the contact hole with metal. CONSTITUTION:The contact hole 7 is formed in an insulation film 2 on a semiconductor substrate 1 by using resist films 3 and 5 as a mask, and a metallic layer 10 is formed by sputtering a metal to a thickness of the degree that the contact hole 7 is filled.

IPC: G03G15/00
Filed: 1985-01-14
Abstract: PURPOSE:To separate a transfer material surely with simple constitution by flowing a prescribed separating current to a position near the front end in the running direction of the transfer material an stopping discharge in the part of the transfer material following this position. CONSTITUTION:A transfer paper 7 is electrified with the opposite polarity of a toner by a transfer charger 5, and the toner is transferred there. AC discharge which does not remove completely the electric charge given by the charger 5 and does not cause retransfer and DC discharge which compensates for lack of daid discharge are performed in the position of 20-30mm length of the front end part of the transfer material by a separating charger 6. DC discharge is stopped in the part of the transfer material following this position. Thus, the front end part is separated surely from a photosensitive body 10 by the destaticizing action, and retransfer is not performed because the part following the front end part lacks destaticization, and the transfer material is separated surely by the weight of the transfer material.

Filed: 1991-01-17
Abstract: PURPOSE:To improve the transmission efficiency by dividing a space in which a receiver is considered to move into some spaces, selecting one or several spaces in the vicinity of the receiver and sending an infrared ray/optical signal to them. CONSTITUTION:When an infrared ray signal is sent from a receiver 7 to a transmitter, plural light receiving sections 4 of the transmitter receive the signal respectively and give the strength to a comparator circuit 5 respectively. The comparator circuit 5 compares the signal strength to discriminate a space in which the receiver 7 is in existence thereby controlling a distribution changeover circuit 2. On the other hand, a sound signal is given to an input terminal 1 and sent to any light receiving section 3 in a direction of the space in the vicinity of the receiver 7 selected by the distribution changeover circuit 2 depending on the information of the comparator circuit 5. Then the sent infrared ray signal is sent only to spaces in the vicinity of the plural receivers 7. Thus, the transmission quality in the case of using plural optical wireless transmitters in a same space is improved.

IPC: G01B11/08
Filed: 1986-01-10
Abstract: PURPOSE:To improve accuracy by measuring the outside diameter in the cutting part of a bar-shaped cutting tool in a rotating state by an optical type outside diameter measuring instrument of a non-contact type, then moving the outside diameter measuring instrument in the axial direction and making the measurement again when said measuring instrument measures the max. measured value. CONSTITUTION:The max. measured value at the point where a deposit such as dust sticks among the respective measuring positions of an end mill 15 attains an abnormally large value occurring in such deposit if said deposit sticks to said point. The nominal diameter of the end mill 15 as a material to be measured is usually known in many cases. A threshold value (D+h) is, therefore, preliminarily determined and if the max. measured value Di is not smaller than the value (D+h), the presence of the deposit on the end mill 15 is judged and the end mill 15 is axially moved to the next measuring position. A motor 19 for a shaft slide is stopped and the measuring step is started when the feed operation is completed. The abnormally high measured value occurring in the deposit on the end mill 15 is thereby excluded and the accuracy of the measurement is improved.
