Filed: 1987-09-18
Abstract: PURPOSE: To accelerate a response from data input up to display and to flexibly constitute an window by displaying the contents of an active screen memory in accordance with the set state of a field control buffer at the time of overlappedly displaying the contents of respective logical buffers. CONSTITUTION: Character data out of data inputted from an input device are written in the active screen memory and immediately displayed on a display screen 40 in accordance with the set contents of the field control buffer 21. Data for specifying a display state are written in the buffer 21 and the display state of the screen 40 is immediately changed by following the specification. Since the inputted data are written in the memory 22 or the buffer 21, the data are immediately reflected to display. Thereby processing from key entry up to display can be accelerated. Since the display/non-display of data stored in the memory 22 can be set up in the buffer 21 in each character string unit, a window can be flexibly constituted.

Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To measure the error of surface height or the overall thickness of a basic body by employing a multiplex spectral light source and interposing a reference plane between the light source and basic bode. SOLUTION: A light source 28 is a multiplex spectral light source having a specified bandwidth. An incident light 30 is sighted through a lens 32 and introduced to the surface 18 of a basic body 16 at an incident angle θ. The angle θ is set at 70-85 deg. preferably at 78-82 deg.. The incident light 30 is retracted through a reference plane 14 and an air space 12 before being reflected on the surface 18 of basic body 16. The reflected light 34 is refrated again through the air space 12 and reference plane 14. Consequently, a desired Fizeau fringe being employed for measurement of thickness or surface mapping is formed by the phase difference between the light reflected on the surface 18 of bacic body 16 and the light reflected on a reference surface 24.  The image of Fizeau fringe is formed on the CCD array 36 of an electronic camera 38 through combination of a sight optical system 40 and an image lens 42.

Abstract: PURPOSE: To improve the critical current density and critical temp. by specifying the grain size and molding pressure of raw material power and the firing condition of a molding in production of a slid superconductor consisting of Z (specific element, such as Y)Ba 2 Cu 3 O x .  
     CONSTITUTION: The solid high-temp. superconductor having a compsn. corresponding to general formula ZBa 2 Cu 3 O x , which is a single phase powder of the compsn. ZBa 2 Cu 3 O x  is produced. In the formula, Z is Y or elements of atomic numbers 61 to 71 and (x) is 6.5 to 7.2. In this process for production, the ZBa 2 Cu 3 O x  is pulverized until the average grain size of 1 to 2 μ is attained and the pulverized powder is compressed under 1 to 5 kbar and more particularly 2 to 3 kbar, by which the untreated molding is obtd. The molding is heated and sintered for 30 to 360 minutes at a temp. of 920 to 970°C in an atmosphere contg. O 2 . The sintered body is then cooled down to room temp. When the pressure compressing the powder described above exceeds the upper limit, the escape of the O 2  liberated during the sintering is hindered and the density of the product is lowered. When the sintering time exceeds the upper limit, a peritectic decomposition reaction is excessively vigorous to make the critical temp. too low.

Filed: 1990-09-05
Abstract: PURPOSE:To generate a continuous membership function with simple circuit constitution by constituting a CMOS inverter with a PMOS FET and an NMOS FET whose threshold level and W/L are set to desired values. CONSTITUTION:A membership function generating circuit is formed by connecting an NMOS FET 3 which is always on and equivalent to a resistor in series with a CMOS inverter comprising the series connection of a PMOS FET 1 and an NMOS FET 2.

The FETs 1,2 being components of the CMOS inverter act like switches and actually, in the CMOS inverter characteristic, a region with a current flowing called the transition region exists. The transition region is fluctuated with a threshold level of each of the PMOS and NMOS and W/L (where W is a width of the gate and L is the length of the gate). When the threshold level and the W/L are designed properly, a desired membership threshold level is obtained.

Title: Current shaping device for temperature layered type heat accumulating tank
Inventor: MAEDA SHIGEYA
IPC: F24H9/00
Filed: 1983-12-16
Abstract: PURPOSE:To increase the amount of heat accumulation or reduce the cost of the heat accumulating tank by a method wherein current shaping plates are provided on the same planes as submerged dams to eliminate a header tube or other flow distributing devices. CONSTITUTION:A small cushion tank is constituted of two pieces of channel type members 2, 2. Vertical current shaping plates 3 are arranged at the tip end of the submerged dams 2a and the upper outflow and inflow ports thereof are arranged to the upper places of a water level while the lower outflow and inflow ports are arranged on the bottom surface of the heat accumulating tank. Accordingly, hot-water and cold water, overflow from the channel type members or cushion tanks through header tubes or circulate, are distributed by the current shaping plates 3 at the upper (or lower) parts of the submerged dams, which are bottle necks, therefore, the flows will never disturb a temperature jumping layer (a part whereat the temperature is suddenly changed in the vertical direction in the tank) and are stagnated in or recirculated out of the uppermost (or lowermost) layer of the tank. Space between the cushion tanks and the water level or the bottom surface of the tank becomes cushion area. Accordingly, the deterioration of current shaping effect due to miniaturization or the increase of deviated branch flows due to the same will never exist. Any of lattices, perforated plates or other water permeating plate bodies such as nets or the like may be used as the current shaping plates 3.

Abstract: PURPOSE:To prevent a spark discharging part from peeling off by forming the discharging part in the tip of a center electrode in a cylindrical clad chip consisting of an iridium or iridium alloy inner core and a nickel alloy making contact with the outer surface of the core, and specifying the size of the clad chip. CONSTITUTION:In a spark discharging part 8 in the tip of a center electrode 3 opposing to an outer electrode 4, the diameter A of the tip part of the center electrode 7, the diameter B of an iridium or iridium alloy inner core, and the thickness C of the outer cylinder 10 of a nickel alloy satisfy the followings; A<=1.5mm, 0.2<=B<=0.8, C>=0.1mm. That is, as a spark discharging part 8, such a cylindrical clad chip 10 is welded with the center electrode 7 made of a nickel alloy so that the chip is prepared by welding nickel alloys themselves and the chip has improved resistance to peeling off even used at high temperature. As a result, even if the spark discharging part suffers from high temperature and thermal stress is caused between the center electrode and the spark discharging part owing to long time driving or high speed rotation driving, the spark discharging part is prevented from peeling off.
