Title: Airtightness measuring method for container
Inventor: OSHIDA MAMORU
IPC: G01M3/26
Filed: 1987-07-31
Abstract: PURPOSE:To remove the influence of variation in atmospheric pressure and variation in gas feeding ability by investigating the pressure difference of gas fed forcibly into a container for a certain time. CONSTITUTION:When a bottle pusher 3a contacts the mouth of the container 1, a gas pump 11 injects and discharge air into and from the container 1. A pressure sensor 13 which detects the pressure in the bottle pusher 3a (in the container 1) is connected to an arithmetic means 10 which controls an elevation device 12 for elevating the bottle pusher 3a and a gas pump 11. The pressure value at the time of forcible feeding is stored as 1st pressure, the pressure in the container after the container is left in a pressure state for a certain time is measured as 2nd pressure, and the difference between the 1st pressure and 2nd pressure is calculated by the arithmetic means 10 and compared with a specific value. Consequently, even if the pressure at the time of the gas charging deviates from a prescribed pressure value, the reliability of measurement is improved.

IPC: G11B19/06
Filed: 1990-07-19
Abstract: PURPOSE:To prevent dust from sticking to an optical recording medium and a pickup by controlling the rotation of the optical recording medium when the optical disk device has not been accessed by a controller for more than a prescribed time. CONSTITUTION:A time measuring means for detecting that the prescribed time has elapsed since a host computer 15 issued its last instruction is equipped with an OR gate 14, a counter 9 and a flip-flop 10. Then, a reset terminal RST of the counter 9 is impressed by an access pulse (a) from a drive controller 8, while an input terminal of the OR gate 14 is impressed by a clock pulse (b) from a clock generating circuit, for instance, a frequency dividing circuit of a crystal oscillating pulse. Then, when the optical disk device 1 has not been accessed by the host computer for more than the prescribed time, the rotation of the optical disk 13 is stopped. By this method, static electricity caused by friction between the optical disk 13 and the air is suppressed, thus preventing dust from sticking to the optical disk 13 and the pickup 18.

Filed: 1986-08-18
Abstract: PURPOSE:To maintain the concentration of magnetic particles in a developer within a constant range by attracting magnetic particles to a no-image area on an image carrier and spending the magnetic particles in the developer. CONSTITUTION:A developing bias voltage becomes 0V through the short-time operation of a relay contact point 12 when the no-image area at a position which does not correspond to a form on a photosensitive drum 1 passes through a developing device 4. This time is determined according to the mean amount of toner spent for one copy. At this time, a large potential different is generated between the surface potential of the photosensitive drum 1 and a grounded developing sleeve 9 and the magnetic particles on the surface of the developing sleeve 9 are attracted o the photosensitive drum 1 and recovered and removed by a cleaner without being transferred onto the form. Consequently, the concentration of toner in the developer is maintained automatically within a prescribed range, so no magnetic particles stick and an excellent image is obtained at all times.

Title: High-temperature-functioning shape memory alloy, and its production
Inventor: OTSUKA KAZUHIRO
IPC: C22C14/00
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To provide a high-temperature functioning shape memory alloy capable of exhibiting excellent shape memory effect and superelasticity effect at high- temp. environments, and its production. SOLUTION: This alloy is an Ni-Ti-Pd shape memory alloy having a composition consisting of, by atom, >50-52% Ti, 15-50% Pd, Ni as an essential element, and inevitable impurities. Further, at least one kind among a Ti2 Ni precipitated phase, a precipitated phase where part of Ni in a Ti2 Ni is substituted by Pd, and a Ti2 Pd precipitated phase, each having <=100 nm grain size, is dispersed in the crystalline grain of the alloy. The alloy is hot-worked into prescribed shape at 700 to 1000 deg.C and then heat-treated at 400 to 600 deg.C, by which the shape memory alloy can be produced. Because the precipitated phase of <=100 nm grain size inhibits the occurrence of slip, excellent shape memory effect and superelasticity effect can be obtained at high temp.  The above alloy can be easily obtained by means of hot rolling and heat treatment alone while obviating the necessity of cold working liable to cause defects.

Abstract: PROBLEM TO BE SOLVED: To smoothly supply a material from a material supply opening to a molecular beam cell by fitting an agitating bar penetrating an inner cylinder on an outer cylinder, preparing slits for guiding the movement of the agitating bar on the side faces of the inner cylinder, and permiting the agitating bar to move in the material included in the bottomed inner cylinder in order to eliminate clogging of the material therein. SOLUTION: An agitating bar 20 is fitted in an outer cylinder 7 in such a manner that it slides in slits 21 for guiding the movement thereof which are prepared on a bottomed inner cylinder 8 and it penetrates the cylinder 8. When a material for molecular cell is subjected to be supplied, top ends of the cylinders 7 and 8 are both lowered to the upper side of opening of the molecular cell and only the cylinder 8 is further lowered to release a material supply opening 8b. The bar 20 is moved in the material included in the cylinder 8 so as to agitate the inside. When the supply of the material is stopped due to clogging, the bar 8 is slided up and down in the cylinder 8 to agitate the material, thereby eliminating the clogging. Thus, the material can be smoothly supplied from the material supply opening to the molecular cell.
