Title: Chiller type cryogenic refrigerator
Inventor: NAGAO MASASHI
IPC: F25B9/00
Filed: 1989-09-29
Abstract: PURPOSE:To simplify the structure, to accelerate heat exchange between a chilling tube and helium gas, and to improve the refrigerating efficiency by employing the helium gas as working gas, and forming a chilling unit of a vessel having a space therein and a hole for introducing the helium gas into the space. CONSTITUTION:A vessel 12 for introducing helium gas for forming a second stage chilling unit has a space therein. A hole 30 is opened at the vessel to introduce helium gas 29 into the space, and a heat transfer plate 31 accelerates heat exchange of the gas 29. In a chiller type cryogenic refrigerator composed in this manner, the gas 29 used as working gas can be introduced into the vessel 12. Accordingly, a supply tube 27, a pressure regulator 28 can be eliminated. When the size of the fine hole 30 is set suitably, the pressure in the vessel 12 can be set in suitable range of intermediate pressures A', B', C', D' between high and low pressures. Thus, the gas 29 is suitably moved in the vessel 12 to accelerate heat exchange with the inner wall of the vessel 12.

Title: Selective compiling system
Inventor: NISHIYAMA KENJIRO
IPC: G06F9/44
Filed: 1987-10-09
Abstract: PURPOSE:To selectively translate a desired program unit out of a source program by identifying a key word put into the head of the program unit received from the source program and replacing said key word with a comment for translation of the program unit. CONSTITUTION:When a user calls a compiler 10 via a start means 4, an identification means 1 is started to decide the presence or absence of a key word which is preliminarily put into the head of a line unit to show the compiling start to the reading actions of each source line out of a source file 5. If the presence of the key word is recognized, a replacement means 2 is started and the compiling start key word is replaced with a comment in the file 5. Then a translation means 3 is started. The means 3 reads a source line out of the line replaced with a comment and translates the source line continuously until a program unit end sentence is decided. Thus the selective translation is possible and the translating time is shortened.

Title: Cathode-ray tube device
Inventor: YANO TOMOYA
IPC: H01J29/48
Filed: 1986-10-28
Abstract: PURPOSE:To uniformalize focusing voltages in the vertical and horizontal directions by shaping an aperture of at least one of electrodes, which compose a main electronic lens, so that its diameter in the vertical direction is different from that in the horizontal direction when an electron beam transmission aperture is formed so that diameters are different from each other in the vertical and horizontal directions is formed. CONSTITUTION:When an electron beam transmission aperture h1 at the first grid G1 is formed into a vertically long shape, for example, a difference in focusing voltages, which is based on a difference in positions of crossover points concerning the horizontal and vertical directions, is formed into a difference in main electronic lens effects concerning the horizontal and vertical directions by selecting an electron beam transmission aperture hA of an anode electrode to which a high voltage is applied to compose the main electronic lens. Thus, a focusing voltage can be uniformalized in the horizontal and vertical directions of the electron beams in order to obtain just focusing on a fluorescent screen. Besides, an electron beam spot on the fluorescent screen can be set in the narrowest shape, and a shift in coloring can be avoided, so that resolution can be improved.

Title: Digital filter and servomotor controller
Inventor: HASHIMOTO ATSUSANE
IPC: H02P29/00
Filed: 1996-09-05
Abstract: PROBLEM TO BE SOLVED: To provide a digital filter of small phase delay, and a servomotor controller which resonance of a servomotor can be prevented with excellent responsibility by using the digital filter. SOLUTION: This digital filter 7 outputs the following with every operation period; twice mean value of a present value sampled with a specified operation period and a sampled value before (n) operation periods. Phase delay of this digital filter 7 is small.

For example, resonance frequency component contained in a current command outputted from a speed control part 4 is eliminated with the digital filter 7. In this case, it is unnecessary for the gain of the speed control part 4 to be set small, so that resonance can be prevented without deteriorating responsibility of control.
