Title: Ion working device
Inventor: INOUE KIYOSHI
IPC: C23C14/24
Filed: 1981-03-30
Abstract: PURPOSE:To perform arbitrary lamination and ion working by irradiating the plural ion generating sources and neutral particle generating sorces provided in one vacuum chamber simultaneously or in combination by leaving time lags. CONSTITUTION:The inside of a vacuum chamber 6 is maintained at a suitable degree of vacuum by the evacuation through an air releasing port 61, and respective ion generating sources 1-5 are heated by heaters. The thermoelectrons heated by the heater are discharged by the discharge voltages applied to respective discharge electrodes 11-51 and ionize the gases introduced through respective supply ports. It is possible to generate ions efficiently by applying pulse voltages as the discharge voltages to be applied to a terminal 8. The ions are drawn out by the voltages applied to electrodes for forming electric fields for drawing-out from a terminal 10 and colldie against the work 7. The ion irradiation from the sources 1-5 are changed over successively to ion formation and ion drawing-out by rotary switches 111, 112. It is possible to use >=1 among the about-mentioned sources 1-5 as neutral particle generating sources.

Title: Method for testing reheating crack sensitivity
Inventor: HAMADA KUNIHIKO
IPC: G01N3/18
Filed: 1982-03-25
Abstract: PURPOSE:To make it possible to test a steel material having any chemical component in adequate evaluation, by a method wherein a tensile test piece is fabricated from the steel material and reheating crack sensitivity generated at a welding heat affected part is evaluated by a value of contraction of area in a tensile test. CONSTITUTION:A tensile test piece 1 and an oblique Y shaped restriction crack test piece 2 are fabricated at first from a steel material, and after heat history is imparted to the tensile test piece 1 so as to reproduce the coarse particle region of a welding heat affected part, a tensile test is carried out at a temp. wherein a welded part is heated after welding application to ask a value of contraction of area by measuring the diameter of the cut surface thereof after cutting. On the other hand, the oblique Y shaped test piece 2 is welded, and after the welded part is subjected to heat treatment, it is observed whether reheating crack is generated or not. As the result, because reheating crack is generated when the value of contraction of area is about 15% or less, the reheating crack sensitivity of the steel material can be evaluated high if the value of contraction of area is 15% or less when the tensile test piece having the coarse particle region of the welding heat affected part reproduced thereto is subjected to tensile test at a temp. heated after welding application.

Title: Solid-state image pickup device
Inventor: ANDO FUMIHIKO
IPC: H04N5/335
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To obtain a solid-state image pickup device that covers a desired luminous quantity range over a wide range without increasing the scale of a counter circuit. SOLUTION: A FET switch S2 is closed when '1' is set to a 7th bit, a discharge resistance (ON resistance) of charges stored in a photo diode 12A is decreased and a discharge time constant is decreased, then deeper resetting is attained. Similarly in the case of an 8th bit, when '1' is outputted, the ON resistance at resetting is further decreased and the discharge time constant is furthermore decreased. Thus, in the case of counting number of photons under the same luminous quantity, number of pulses counted per unit time is decreased, resulting in decreasing the sensitivity and widening the dynamic range.

Abstract: PROBLEM TO BE SOLVED: To obtain an antistatic photosensor in which the generation of static electricity is suppressed and by which an object to be detected can be detected precisely by a method wherein a case is constituted of a material whose permittivity has a specific value or lower. SOLUTION: A photosensor 10 is used to detect the residual amount of a toner in a toner tank. Then, one pair of protrusion parts 13, 14 are formed so as to sandwich a gap 12 as the passage of the toner, as an object to be detected, from a body 11 attached to the outside face of the tank which stores the toner. A light-emitting element 15 is arranged and installed inside the protrusion part 13, and a light-receiving element 16 is arranged and installed inside the protrusion part 14. A case 19 is formed of a material whose permittivity is low, i.e., a material whose permittivity is 2.7 or lower according to a measuring method by the ASTM D15010Hz, e.g. polystyrene, polyprolylene, polyethylene or the like.  Thereby, the object to be detected, dust particles and the like are hardly stuck to the surface of the case 19 due to the friction of the case 19 with the object, to be detected, the dust particles and the like. Consequently, an optical path is not disturbed by an obstacle due to the electrostatic charge of the case 19.
