Abstract: PURPOSE:To enable recording with excellent picture quality free from uneven picture image by constituting the title method in such a manner that the level of an accelerated electric field voltage to be applied to a transverse electrode is variably set according to the position of the transverse electrode. CONSTITUTION:According to the constitution of the title method, when one of transverse electrodes 42-1 to 42-6, where the facing gap between an ion flow controller 40 and a recording medium 16 is put in the position of the minimum gap, is selected, the minimum accelerated electric field voltage is applied thereto; and when the transverse electrode in the position of a specific gap, where the facing gap becomes larger, is selected, a large specific accelerated electric field voltage corresponding to the size of the specific gap is applied thereto. As a result, the intensity of an ion passing accelerated electric field formed in an ion flow passing hole H provided in the position, where the facing gap is comparatively large relative to the intensity of an ion passing accelerated electric field formed in an ion flow passing hole H provided in the position in which the facing gap is smallest, is increased to the intensity corresponding to the size of the gap. Thus, the ion quantity of all ion flow reaching the recording medium 16 can be made uniform.

Title: Oscillation circuit, phase synchronization circuit, phase interpolation circuit, phase adjustment circuit and phase coupling circuit
Inventor: MICHIMASA SHIRO
IPC: H03K5/13
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To improve a phase resolution of a oscillation circuit more than a limit level of the resolution determined by a specific delay of delay elements being components of the circuit. SOLUTION: Phase coupling circuits 13a-13f make a relation of phases of output signals of two corresponding delay elements. For example, an output of the delay element 12a of a ring oscillator 12 is controlled by phase coupling circuits 13a, 13b so that a relation of a phase of outputs of delay elements 11a, 11b of the ring oscillator 11 is stably controlled. Thus, first and second ring oscillators 11, 12 maintain the oscillation so that the state of the phase is temporally shifted by a half of the delay time of each delay element. As a result, a time interval of the state of phase during the oscillation is nearly a half of the delay time of each delay element so that the resolution of the oscillation circuit in the state of phase can be improved up to about twice a limit level depending on the delay time of the delay elements.

Abstract: PURPOSE:To conduct lining in a simple manner at a low cost by a method wherein a polyolefin resin tube is deformed into a lining material by being heated and cooled, and after the lining material in a softened state is inserted into an object tube, the lining material is reheated to be recovered and expanded to line the inner surface of the object tube. CONSTITUTION:A polylrefin resin tube having an outer diameter equal to or larger than an inner diameter of a tube to be lined is deformed so as to be inserted into the tube to be lined at a temperature not less than 60 deg.C but below a melting temperature of a polyolefin resin. After that, the polyolefin resin tube is cooled to a temperature 30 deg.C lower than the deforming temperature to be set in the deformed shape. In this manner, a lining material is formed. In addition, after the lining material is heated to be softened, it is inserted into the tube to be lined. Furthermore, the inserted lining material is heated to at least a temperature 10 deg.C lower than the deforming temperature to be recovered and expanded to line the inner surface of the tube. For example, a steam is supplied to a reduced-diameter tube 2 inserted into an existing tube 8 from a boiler 6 through a tube 7 to bring the lining material into close contact with the tube 8.

IPC: G01N29/04
Filed: 1987-12-26
Abstract: PURPOSE:To surely detect a defective part on a material boundary surface by making an ultrasonic wave perpendicularly incident on the material boundary surface and comparing the attenuation of the multi-reflected echo of the ultrasonic wave with a preliminarily obtained multi-reflected echo attenuation curve of an indefectible part on the material boundary surface. CONSTITUTION:An ultrasonic wave is made perpendicularly incident on a material boundary surface 3 of a member 2 like a clad material, which consists of members A and B different in material from each other, from an ultrasonic probe 1. The reflected echo from the surface 3 is not only partially propagated to the probe 1 but also repeatedly reflected in the member 2 to become the multi-reflected echo, and this echo is detected by the probe 1 to obtain a hard copy. It is compared with a preliminarily obtained hard copy of the indefectible part, and a peeling part is decided if the obtained hard copy is on the outside of an error range. Consequently, peeling of the material boundary surface or a contact-defective part is surely detected.

Title: Organic el luminous element
Inventor: ARAI MICHIO
IPC: H05B33/26
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To prevent contrast from being lowered without providing a reflection resistance layer by sequentially forming an anode, an luminescence layer, and a cathode layer on a translucent substrate and specifically ranging light transmission rate in a luminous wavelength band area of the anode. SOLUTION: A semi-translucent anode essentially consists of a translucent material such as a tin doped indium oxide (ITO), a zinc doped indium oxide (IZO), which is superior in affinity with a coloring component and easiness in adjustment of light transmission rate. Here, light transmission rate of the semi-translucent anode is 30 to 70%. If 70% is exceeded, an effect of prevention of lowering contrast is eliminated. If it is less than 30%, light emitting from the luminescence layer itself is attenuated, and required brightness cannot be obtained. Light transmission rate denotes ratio of incident light to emitting light in a wavelength region of at least 100nm containing luminous wavelength area. Brightness is measured by a luminescence gauge or the like, and contrast denotes ratio of brightness of the luminescence part and the nonluminescence part.

Abstract: PROBLEM TO BE SOLVED: To provide a capacity variable compressor for attempt compatibility between control of a normal discharge capacity for holding stability of a room temperature and quick decrease in a discharge capacity for an emergency evacuation at the time of emergency. SOLUTION: A differential pressure detector 36 detects differential pressure ΔP(t) between two of pressure supervisory points P1, P2 which are set in a refrigerant circulating circuit for presuming as an index of a refrigerant discharge capacity of a compressor. A control device 60 calculates a setting differential pressure of a control target value on the based of an outer information such as a temperature and the like detected by a temperature sensor.
