Title: Laminated polypropyleneterephthalate film
Inventor: MORISHIGE CHIKAO
IPC: C08J7/04
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To improve an adhesive strength by providing an adhesiveness reformed layer consisting of copolymer of ester resin, acrylic resin, urethane resin and at least one kind of these copolymers on one surface of a polypropylene terephthalate film. SOLUTION: At least one surface of a polypropylene terephthalate film, an adhesiveness reformed layer is furnished which consists of ester resin, acrylic resin, urethane resin, and one kind of these copolymers. The adhesiveness reformed layer can be formed by applying application liquid on a biaxially oriented polyester film base material, or applying application liquid on an unoriented or uniaxially oriented polyester film base material to then be dried, and carrying out thermal fixation as required after performing uniaxial orientation or biaxial orientation. In this manner, a sufficient adhesive strength is obtained with the consequence that defects can be supplemented with respect to a polyethylene terephthalate film and a polyamide film.

Title: Information recording disk and its reproducing device
Inventor: SHIYUKUNAMI SHIYUUICHI
IPC: G11B7/005
Filed: 1994-11-30
Abstract: PURPOSE: To obtain an information recording disk where the entire amount of recorded information is increased by recording an information signal along with a lead-out notice signal and a lead-in notice signal at a region which is adjacent to the information signal regions of a lead-out signal region and a lead-in signal region and an information recording disk reproducing device for reproducing the information recording disk. CONSTITUTION: A possibility where neither lead-out signal nor lead-in signal can be read is prevented when the exclusive regions for a lead-out signal region 1 and a lead-in signal region 2 are narrowed and an optical pickup 14 is carried speedily in FF and FB modes. Therefore, when the lead-out notice signal and the lead-in notice signal are detected, the optical pick-up 14 is transferred at a lower rate than the standard rate for traveling while intermittently reading the sub mode in FF and FB modes and information is reproduced without any information loss.

Inventor: NAI HOTSUKU RUII
IPC: H01R13/639
Filed: 1991-12-09
Abstract: PURPOSE: To provide an electric socket in which the durability of a latch member is improved. CONSTITUTION: A slot 22 for the purpose of inserting the base terminal of a circuit substrate is formed in the socket body 14 of socket 12 and a coil spring 66 is inserted in a hole 26 continuing to downward of this slot 22. Near both end parts of the slot 22, latch member 38 for pinching the circuit substrate are subjected to mold formation integrally with the socket body 14. A projection 46 of this latch member 38 engages with the slit of the circuit substrate. A metallic reinforcement plate 54 is arranged behind the latch member 38. Any excessive deflection in the latch member 38 taking place at the time of attaching/detaching the circuit substrate to/from the slot 22 of a socket 2 is restricted by the metallic reinforcement plate 54.  In addition, since the circuit substrate inserted in the slot 22 is subjected to application of the force of a coil spring 66 so as to be pushed upward, the projection 46 of the latch member 38 and the slit of the circuit substrate engage each other strongly.

Title: Display input device
Inventor: MATSUSHITA SHIGENORI
IPC: G06F3/0487
Filed: 1989-12-15
Abstract: PURPOSE:To improve operability by providing a correction means correcting coordinate data obtained by means of an input means in accordance with a correction value used for displaying a cursor in a desired position detached by a previously set distance. CONSTITUTION:The cursor displayed on a display part screen is set to be a reference and the correction value decided by instructing a desired cursor position coordinate by the input means 13 is stored in a memory 18. At the time of displaying the cursor, the correction value stored in the memory 18 is read and the cursor is displayed by detaching it by the prescribed interval from the position coordinate which the input means 13 actually instructs on the display part screen. Consequently, a desk space is not occupied such as a mouse, and the cursor is prevented from being hidden behind a hand and a pen in pointing by a tablet and the input pen, whereby the cursor can be displayed in a visible position. Thus, operability can be improved.

Title: Cleaning method of semiconductor substrate
Inventor: OKI ICHIRO
IPC: H01L21/304
Filed: 1991-12-10
Abstract: PURPOSE:To enable a semiconductor substrate to be lessened in metal contamination in dilute hydrofluoric acid by a method wherein the surface of the semiconductor substrate is dipped into the mixture of hydrofluoric acid and hydrochloric acid for a prescribed time. CONSTITUTION:5ppm of each of Fe, Cr, Ni, Cu, Zn, and Ti ion is added to the mixture of 1% hydrofluoric acid and 3% hydrochloric acid to forcibly contaminate a cleaning solution. Then, a silicon substrate is dipped into the mixed solution for two minutes and then rinsed with pure water for five minutes, and the substrate is naturally dried up. As mentioned above, hydrochloric acid is added to hydrofluoric acid, whereby Cu is sharply restrained from separating out as compared with a case where a cleaning operation is carried out with hydrofluoric acid where no hydrochloric acid is added, and it is found by the analysis of metal elements that contamination caused by Fe, Zn, and Ni is almost prevented or remarkably lessened.

Title: Passenger conveyor control device
Inventor: HIROSE MASAYUKI
IPC: B66B31/00
Filed: 1990-11-29
Abstract: PURPOSE:To troubleshoot an input circuit of a safety device with an conveyor in operation by checking a microcomputer input signal when opening and closing control is conducted of the contact point of a breakdown diagnosing relay provided in series between a conveyor safety device and a microcomputer. CONSTITUTION:A microcomputer 81 has a breakdown troubleshooting relay 50CH, which is normally closed by means of an output memory device 203 while a conveyor is in operation but released to open a contact point 50ch. Because the contact point 50ch is closed under the condition of safety switches 46, 47 not actuating, the microcomputer 81 detects that a level conversion circuit 73 and input PA0 to PAn of the microcomputer 81 have converted from H to L when the contact point 50ch opens. On the other hand, if the safety switches 46, 47 are out of order during conveyor operation, the input signal of the microcomputer 81 is remained H, even if the contact point 50ch of a relay 50CH has opened, and the microcomputer 81 detects the breakdown of the safety switches 46, 47. Thus the input circuit of a safety device can be troubleshooted even while a conveyor is in operation.
