Inventor: IIMORI AKIROU
IPC: G03G21/00
Filed: 1981-03-31
Abstract: PURPOSE:To securely inform a user that copying is finished and to improve operation efficiency by equipping a voice generator which sends information on the remaining number of copies when a remaining-sheet-number detection part detects the prescribed remaining number of copies during copying operation for many sheets. CONSTITUTION:An operation state detection part 60 detects the operation state of an operation part 30 by a user, and the maintenance state of a main body. A remaining-sheet-number detection part 70 detects the remaining number of sheets to be copied for a preset number, and then outputs signals when the remaining number of copies is, e.g. ''3'' and ''0'' (ending of copying). A timer 80 is energized when copying starts, and outputs a voice generation permission signal A a certain time later if the copying stop operation of the detection part 60 is not detected and the detection part 7o does not detects the remaining number of sheets ''0''. A condition judgement part 100 outputs a voice generation command for the detection results of the detection parts 70 and 90 only when the timer 80 outputs the signal A.

Abstract: PURPOSE:To increase the grains of a single crystal by irradiating a surface for vapor deposition with a neutral atom beam of an inert gas having low activity while executing the vapor deposition of a thin-film material and utilizing the effect to be exerted on the crystal structure of the irradiation. CONSTITUTION:An Si oxide film 12 is provided by thermal oxidation on the surface of, for example, an Si single crystal substrate 11. Gaseous Ar is introduced from a conduit 14 into a gage type ion source 15 and only the Ar ions is taken out to form the ion beam. An Si single crystal target 17 of a crystal face (111) is irradiated at 45 deg. incident angle by this Ar ion beam to cause repulsion and neutralization, by which the Ar atom flow lowered in energy is formed. This flow is passed through a filter 16 by which high-energy charge particles are removed. The atom flow is made to arrive together with the Si sputtered from the target 17 on the substrate 11. Plural pieces of the above-mentioned Ar atom flows are formed and these flows are so disposed as to be perpendicular to the densest crystal face of the single crystal having desired crystal bearings and the surface for vapor deposition is irradiated with these flows.

Title: Thermal transfer printer
Inventor: MOROZUMI SHINJI
IPC: B41M5/382
Filed: 1985-03-12
Abstract: PURPOSE:To enable printing speed to be easily enhanced without requiring any complicated system, by using a light as a means for generating heat in a transfer sheet. CONSTITUTION:An output from a light output device for emitting a beam 13 of laser or the like, e.g., a laser oscillator 10, is modulated and scanned on a thermal transfer sheet 11. The beam provides a minute spot of 50-10mum in size, and when it is incident on the sheet 11, it is converted into a large quantity of heat at and around the point of incidence. In the same manner as in the case of a thermal head, the heat thus generated causes transfer of a coloring material to a paper 12. Since the laser beam can be concentrated on a minute part, it is possible to raise the temperature of only that part at high speed. In addition, the heating value is determined by the intensity of the beam and power can be increased as compared with that of a conventional heating resistance, high-speed heat response is ensured.

Abstract: PROBLEM TO BE SOLVED: To prevent the temp. gradient of a sheet guide means and to obviate unequal development by making the width of a heating means longer and constituting the heating means in such a manner that the heating part thereof extends outside from both sides in transverse direction of sheet guiding means. SOLUTION: The width (the length of the heating part of the heating means in a direction orthogonal with the transporting direction of the sheet 32) of the heating means is longer than the width (the max. length of the sheet guide means 25 in the direction orthogonal with the transporting direction of the sheet 32) of the sheet guide means 25 (heating guide plate) 25. The ends of the heating part extends outward from both sides in the transverse direction of the sheet guide means 25. The ends of sheet pressurizing means 27 are thus made longer and the ends of the sheet 32 are pressurized to a wider range by the heating guide plate 25, by which the time for contact is prolonged and the heat quantity to make up the temp. drop of the heating guide plate 25 and rollers is eventually obtd.  In such a case, the similar effect is obtd. even if the sheet pressurizing force is so set as to vary at the center and at the ends.

Title: Release agent for shoe sole mold
Inventor: MIHARA TATSUO
IPC: B29C33/64
Filed: 1995-02-13
Abstract: PURPOSE: To develop good releasability by reducing surface tension to a degree unnecessary for using fluorocarbons by using a release agent constituted of a silicone and an isoparaffinic oil in a predetermined wt. ratio. CONSTITUTION: A release agent for a shoe sole mold is constituted of 10-40wt.% of a silicone and 90-60wt.% of an isoparaffinic oil. The content of the silicone is set to 10-40wt.% because the surface tension of the silicone is lower than that of the isoparaffinic oil and the silicone is easy to spread up to the fine parts of a mold and, when the content of the silicone is below 10-40wt.%, the surface tension of the release agent becomes high and a trouble such that the silicone becomes difficult to spread to the fine parts of the mold is generated and, when the content of silicone exceeds 10-40wt.%, the silicone is applied too much and a trouble such that a product is damaged by the release agent is generated.  Isopropane of which the surface tension is higher than that of chloro fluorocarbon 113, for example, isoparaffin is used and a gelly like silicone oil good in releasability is used.

The door 1 is usually kept locked and never opened freely. Then the lock of the rental room is released for application of a user when the due coins are thrown into the device 3. The door is locked again after the user entered the room and the user can occupy the room for a certain period of time in accordance with the paid charge. When the user leaves the room, the door 1 is unlocked after detecting a fact that the user operated the doorknob 2. In this case, however, the locked state is kept and the door 1 is never opened in case the due charge is not paid yet. Thus the unmanned collection of charges is possible and the operating efficiency is improved for the rental rooms.
