Title: Tape running driving device for friction capstan driving system
Inventor: SATO TSUGUO
IPC: G11B15/43
Filed: 1989-12-18
Abstract: PURPOSE:To from a stable servo loop at the time of a small angular error by amplifying detection outputs of take-up reel side and supply reel side tape tension detectors. CONSTITUTION:Angles of take-up side and supply side tension detectors TSt and TSs which detect angles of take-up reel side and supply reel side tension arms ATs and ATt to detect the tape tension are detected to detect the tape tension. An amplifier 27 is provided which amplifies the detection outputs of take-up side and supply side tension detectors TSt and TSs, which detect the tape tension, to supply them to level comparators CPs and CPt. The gain of this amplifier 27 is reduced when the angular error of take-up side and supply side tension arms ATs and ATt is small, and it is increased when this angular error is large. Thus, the servo band is extended to improve the responsiveness when the angular error is large, and a stable servo loop is obtained when it is small.

Title: Mold
Inventor: MIYAIRI KAZUYOSHI
IPC: B29C45/26
Filed: 1990-11-28
Abstract: PURPOSE:To omit waste of material and to prevent deterioration of resin in a hot runner by forming an undercut part in the tip part of a sprue bush and providing a recessed part into which the tip part of the sprue bush is freely inserted to the rear of an insert die regardless of presence of the cavity of the insert die. CONSTITUTION:Since an undercut part 44 is formed in the tip of a sprue bush, a runner branch is tightly stuck to a fixed plate side and gate cut due to mold opening is performed without especially providing a runner lock pin. Moreover since the position of a runner hole is freely changed in a range within the width of a recessed part 59 in the rear of an insert die, the degree of freedom for designing the gate position is increased. Further since only the small runner branch described hereunder is provided between a runner stripper plate 36 and the rear of the insert die, waste of material can be reduced. The runner branch is formed of a sprue bush resin path 57, a runner 60, the recessed part 59 of the insert die 38 and the undercut part 55 of the sprue bush 53. Furthermore since the same recessed part 59' as the molding insert die 38 is formed to the rear of the insert die substitute, resin in a hot runner block 49 is not stagnated and deterioration and decomposition of resin are not caused.

Title: Corrosion protection method for metal sheathed cable
Inventor: HATA RYOSUKE
IPC: H01B13/22
Filed: 1987-12-23
Abstract: PURPOSE:To apply a corrosion protection layer of stabilized performance by applying corrosion protection compound added with powder mixture to the outer surface of a corrugated metallic sheath and scraping off excessive mixture with a cylindrical tool of an inner diameter same with the diameter of the ridge top portion of the sheath. CONSTITUTION:Corrosion protection compound 6 added with mixture 5 is put in a bath 7, drawn up with a pump 8, dripped through a pipe 9 onto a metallic sheath 2 of a cable so that the compound is applied on the circumference of the sheath 2, and the amount which has not been applied to the sheath is returned to the bath 7. A scraping tool 10 of cylindrical rubber of an inner diameter same with the diameter of the ridge top portion of the sheath 2 and a length to cover 3-10 ridges is placed in front of the outlet of the pipe 9. As a result, excessive compound 6 on the circumference of the sheath 2 is removed with the scraping tool 10 and only the bottom portion of the ridges are practically filled. An extrusion device for a corrosion protection layer 4 is placed immediately after the scraping tool. Since the granular mixture is uniformly applied over the circumference of the sheath and does not get into the corrosion protection layer, stabilized corrosion protection performance is obtained.

Title: Standby condition controller for wet copying machine
Inventor: SHIROSUGI KOJI
IPC: G03G21/10
Filed: 1988-12-28
Abstract: PURPOSE:To copy without waiting time through a simple operation by providing a temperature detector for detecting a temperature of a photosensitive body or developer and a control means for continuing a copying operation mode when the detected temperature is equal to or less than the prescribed value. CONSTITUTION:Developer 19 returns into a developing tank 9 while it comes into contact with the photosensitive body 2 in a developing unit 5 and a cleaning unit 3. Since the developer 19 has extremely good conductivity, the temperature detector 8, provided in the developer tank 9, for detecting a temperature of the developer can be also used as the temperature detector for the photosensitive body 2. When the temperature of the developer 19 or the photosensitive body 2 is equal to or less than the prescribed value, a wet copying machine is maintained in a copying completion condition; therefore, when a next user makes a copy, he can immediately make a copy without waiting time owing to a cleaning process, through such a simple operation that a print key is depressed after an original is set. This achieves copying always without waiting time unless the main switch of the copying machine is set manually turned off.

Title: Freezing device
Inventor: HATTORI NAOKI
IPC: F25B1/00
Filed: 1990-11-30
Abstract: PURPOSE:To reduce the number of generating times and a generating time of fluid noise of a bypass before the starting of a compressor by a method wherein by effecting opening only when a pressure on the high pressure side exceeds a set value, high pressure gas is caused to bypass, and after the pressure on the high pressure side is reduced to a condition on which starting is practicable, starting is carried out. CONSTITUTION:A bypass pipe 10 for interconnecting the high pressure side and the lower pressure side of a compressor 1 is arranged, and a high pressure pressure regulating valve 14 is located in a bypass pipe 10. When a high pressure exceeds a set value, the high pressure pressure regulating valve 14 is opened, and a high pressure gas in a compressor 1 chamber is released to the lower pressure side so that a high pressure gas pressure is reduced to a set value at which starting is practicable. A bypass solenoid valve 11 is opened and a time limit relay is energized, and after a lapse of a specified time, the compressor 1 is run. When a high pressure is below a set value, the high pressure pressure regulating valve 14 is not opened and the compressor can be started without starting bypass. As noted above, since only a necessary amount is caused to bypass without exceeding a range of starting capacity of the compressor 1, the number of starting bypass times and a starting bypass time can be reduced, and the number of generating times and a generating time of fluid noise during bypass can be decreased.

Title: Plasma process device
Inventor: SUGITA YOSHIHIRO
IPC: H01L21/302
Filed: 1989-12-20
Abstract: PURPOSE:To improve controllability and reliability by setting the voltage to be impressed between a pair of electrodes slightly lower than a discharge maintenance voltage and controlling the discharge start of gaseous raw materials by irradiation with rays. CONSTITUTION:A DC power source 5 set lower than the discharge start voltage and discharge maintenance voltage in the state in which the rays of a short wavelength to be described later does not exist is impressed between a pair of the anode electrode 1 and cathode electrode 2 in a reaction chamber in which the gaseous raw materials are packed. The rays 7 are projected in this state from a light source 6 so as to pass the space between the electrodes 1 and 2 in parallel with the electrodes. The rays of the wavelength shorter than the wavelength of UV rays which can dissociate the gaseous raw materials are used as the rays 7. The discharge of the gaseous raw materials arises around the optical path of the light source 7 between the electrodes 1 and 2 in this way and plasma 8 is generated. This discharge state disappears as the rays 7 are shut off. The generation and annihilation of the plasma 8 are, therefore, controlled with high accuracy when a wafer 3 is subjected to CVD.
