Title: File lock managing method
Inventor: KANEI KAZUYOSHI
IPC: G06F15/177
Filed: 1991-11-18
Abstract: PURPOSE:To enable file lock management between machines on network stations, to prevent a dead lock state and to improve processing efficiency for each process. CONSTITUTION:Mount information is acquired from a mount file 6 prepared when the file system of each machine is mounted and according to this mount information, a file judging part 3A of a process A identifies whether a file is a real file or a virtual file. When the file is the virtual file, a message transmission part 4 of the process A transmits a message to a process B and since this process B transmits a message to the process A of the other machine, a real file alpha of a rental source is locked. In the case of locking the file, a file lock processing right is applied to a process C of a machine 3, for example, and each machine locks the file after acquiring the processing right by outputting a request to the machine 3.

Title: Optical encoder
Inventor: KUDO KOICHI
IPC: G01D5/34
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To provide an encoder in which a high-accuracy and very small interval positioning arrangement between a scale and a detecting head is not required, whose whole constitution is simple and which is miniaturized. SOLUTION: Beams of incident light Li (Li1 to Li3) from a light source 10 are changed into beams of parallel light by a lens 11 so as to be incident on the sinusoidal optical characteristic face 13a of a scale 13. Beams of reflected light Lr (Lr1 to Lr3) from the optical characteristic face 13a are received by a light receiving element 12. When sinusoidal photoelectric conversion outputs which are obtained by detecting a change in a quantity of received light which is repeated periodically by the movement of the scale 13 are counted, the movement distance of the scale 13 is detected. When phase difference signals at a 1/4 pitch are compared, the movement direction of the scale 13 is detected. The beams of very-small-spot incident light Li are incident on the optical characteristic face 13a. The beams of reflected light Lr can be detected at high resolution and with high accuracy.  A sufficient interval can be set between a detecting head 15 and the optical characteristic face 13a. A damage accident due to their mutual contact is prevented. The movement due to the vibration in a direction at right angles to the movement direction of the scale 13 can be permitted. An optical encoder can be constituted in such a way that its complicated positioning adjustment is not required as a whole, that it is simple and that it is miniaturized.

Abstract: PURPOSE:To lead a clean liquid coolant only to an ice-making container by measuring the amount of dust contained in the liquid coolant sampled from a sampling pipeline and stopping the supply of the liquid coolant to the container by actuating a three-way valve when the amount exceeds a prescribed value. CONSTITUTION:While liquid nitrogen 3 is used to obtain fine ice particles by freezing pure water finely atomized from a spray nozzle 6, the amount of dust contained in the liquid nitrogen 3 in a nitrogen supply pipeline 20 is always measured with a dust counter 17. When the occurrence of dust is conformed, the liquid nitrogen 3 is led to the external part of the hopper 1a of an ice- making container 1 by switching a three-way valve 14 so as to stop the supply of the liquid nitrogen 3 into the container 1. When the supply of the liquid nitrogen 3 into the container 1 is stopped, the supply of the pure water from the nozzle 6 is also stopped simultaneously. The liquid nitrogen 3 led to the external part of the hopper 1a of the container 1 cools the hopper 1a and prevents temperature rise of the ice particles 8 contained in the hopper 1a.

Title: Cryostat
Inventor: ONO MICHITAKA
IPC: H01L39/04
Filed: 1990-11-09
Abstract: PURPOSE:To restrain heat from penetrating into a cryostat due to the intermittent flow of coolant and to protect a piping against blockage caused by the backflow of coolant by a method wherein check valves different in open pressure and relieving capacity are arranged in parallel to the normal temperature end of the piping. CONSTITUTION:A piping 7 is made to serve to inject cryogenic coolant, to recover the evaporated gas, and to guide a current lead, where one end of the piping 7 is made to communicate with a coolant vessel 3, the other end is located at a normal temperature section penetrating a vacuum heat insulating layer 4, a thermal seal 6, and the wall of the vacuum vessel 3, and check valves 11 are provided in parallel to the normal temperature section. One of the check valves 11, the lowest in open pressure, is so set not large enough in relieving capacity to fully relieve the evaporated gas when the gas flows at a normal flow rate. By this setup, heat conducted through the piping 7 and gas can be made very small, and coolant can be less evaporated. As another check valve 11 large enough in relieving capacity to fully relieve the evaporated gas is provided, even if there is an increase in evaporation due to normally thinkable fluctuation in load, the inner pressure of the coolant vessel 3 can be controlled so as not to become higher than the open pressure of the check valve concerned.

Filed: 1992-10-16
Abstract: PURPOSE:To prevent the degradation of an error rate by providing a flying erase head in a prescribed position on a rotary drum and setting the frequency of an erase signal supplied to the head to be equal to or more than a Nyquist frequency. CONSTITUTION:The flying erase head 10c is provided on the rotary drum provided with rotary magnetic heads 10A, 10B. Then, the erase signal is supplied to the head 10c from an erasing oscillator 11 through an output amplifier 12, and data is erased immediately before the time of rewriting the data in a recording track. The frequency of the erase signal supplied to the head 10c is set to be equal to or more than the Nyquist frequency. Further, the frequency preferably coincides with the Nyquist frequency by using a clock in a recorder. Thus, no gradation of the error rate occurs since the erase signal is attenuated sufficiently at the time point of detecting the data even when the erase signal remains on the magnetic tape.

Thereafter, the toner 11 is collected by a cleaner and to the roller 2, a transfer use bias can be applied through a contact spring 8 from a power source 9. When a cover unit A is released due to a jam, etc., the cam 3 returns to an initial position by force of a spring 4 and comes into contact with the drum 1 by resetting the unit A, and it does not occur that the residual toner 11 contaminates the roller 2.

Filed: 1989-11-21
Abstract: PURPOSE:To grasp the occurrence situation of astigmatism and the focus state in a short time without requiring skill by displaying the wave-form of the photographed image data on a monitor for wave-forms in multiple different straight line directions. CONSTITUTION:Image data 11 are stored in the memory space of an image memory 4. A control device 3 reads the image data along directions of four lines (1), (2), (3) and (4) constituting cursors 10. The occurrence situation of astigmatism can be grasped by comparing four kinds of wave-forms displayed on a wave-form monitor 6. Astigmatism means the situation that the focus state differs for direction, thus it is judged that no astigmatism occurs when the focus state is the same in all directions of four lines constituting cursors 10 and astigmatism occurs when the focus state differs in directions of four lines constituting cursors 10.
