Abstract: PROBLEM TO BE SOLVED: To prevent the suction of foreign matter, the hair, etc., in a pump and the consequent occurrence of trouble by constituting the device in such a manner that hot water is passed to the entire area of a filter and that the hot water is sucked into the pump. SOLUTION: The entire periphery of the outer peripheral surface of the filter 18 is pressed in tight contact with the inner peripheral surface of one filter casing piece 15a and in this state, a spacing is not formed between the peripheral surface of the filter 18 and the inner peripheral surface of the filter easing 15. The hot water presses the filter 18 to a filter retaining body 40 side with its water pressure so that the hot water passes always the inside of the filter 18 forward from the rear surface 18b of the filter 18. The hot water past the filter 18 passes by the hot water pass holes 44 of he filter retaining body 40 and thereafter, the hot water flows upward toward a hot water path 45 in the water flow guide path 43 formed at the other filter casing piece 15b, by which the hot water is gathered in the hot water path 45.

Filed: 1979-04-24
Abstract: PURPOSE:To eliminate crystal defect in a silicon layer resistor without imparting variation to the resistor by treating an irregular Si-B layer produced on the silicon surface by a volatile diffusion at low temperature in oxide atmosphere and oxidizing the layer to form a layer removable with aqueous fluoric acid solution. CONSTITUTION:A diffusion source 1 and a silicon wafer 2 are faced oppositely on a diffusion boat 3, and inserted into a diffusion furnace for a volatile diffusion. At this time the temperature in the furnace is retained so that the source 1 and the wafer 2 may not warp, and N2 or Ar gas containing less than approx. 3% of O2 is fed into the furnace, the furnace is heated to 900-1,150 deg.C, retained for predetermined time for volatile diffusion. Thereafter, only the O2 concentration is varied to approx. 5% in the carrier gas, the temperature is lowered to 600-900 deg.C for low temperature oxidation. Thus, the Si-B layer on the surface of the wafer 2 formed in diffusion is converted into an SiO2-B2O3 glass layer removable with aqueous fluoric acid solution. Then, the glass layer is removed to provide a wafer having uniform layer resistance and no defect.

Title: Equipment for total reflection fluorescent x-ray analysis
Inventor: UKO TADASHI
IPC: G01N23/223
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To facilitate simultaneous analysis of a plurality of elements in a wide range on the same sample, by providing a plurality of irradiation systems each casting a primary X ray on the surface of the sample and by making the incident angles of the primary X rays on the sample differ from each other. SOLUTION: In a first irradiation system 1, a first X-ray source 12 emits an X ray B1. This ray is made monochromatic and converged by a first spectroscope 14 and a W-L β1 ray B2 thus formed is cast on a sample surface 51 at an incident angle ϕ1. In a second irradiation system 2, at the same time, an Mo-Kα ray B2 is cast on the sample surface 51 at an incident angle ϕ2. The irradiation systems 1 and 2 are both positioned in the same azimuth. When the incident angle on one side is set, therefore, the incident angle on the other side is set automatically and thereby setting of the incident angles is facilitated. Each primary X ray B2 excites atoms of a sample 50, fluorescent X rays B3 inherent in elements are generated and part of them enters an X-ray detector 4 and subjected to spectral analysis in a multiple pulse-height analyzer 5.  Since both of the W-L β1 ray and the Mo-Kα ray are used, a plurality of elements in a wide range can be analyzed.

IPC: G06F12/00
Filed: 1987-03-06
Abstract: PURPOSE:To automatically set the access timing of a memory by changing successively the set value of a register by a program and giving an access to memory based on the set value obtained when the coincidence of comparison is obtained between read data and write data. CONSTITUTION:An optimum value is set at each of registers 21-24 and a memory (RAM 1) receives an access based on each set value of these registers to write and read the test data. These test write and read data are compared with each other for each access action carried out based on each set value. When the coincidence is obtained between write and read data of the memory (RAM 1), the relevant value is set at the registers 21-24 respectively as the final set value. Then the access timing is decided based on said final set value and the memory (RAM 1) receives accesses in this timing for prescribed data writing and reading operations. In such a way, the access timing of the RAM can be automatically set with no intervention of man power.

Title: Device and method of measuring distance up to arbitrary target
Inventor: GOODWIN FRANCIS EUGENE
IPC: G01S17/34
Filed: 1985-03-15
Abstract: An apparatus and a method for measuring the distance to an arbitrary target (52) includes a radiation source (62) producing a beam of coherent radiation the frequency of which is continuously varied. The beam is divided into a ranging beam and a reference beam. The'ranging beam is coupled to a ranging interferometer (70), which directs a portion of the ranging beam at the target (52). The ranging interferometer (70) produces a first signal indicative of the phase difference between a portion of the ranging beam directed at and scattered by the target and another portion of the ranging beam which has traveled over a path of fixed length. The reference beam is coupled to a reference interferometer (66). A portion of the reference beam is directed by the reference interferometer (66) along a reference path of a predetermined length X<sub>ref</sub>, and the phase difference between the portion of the reference beam directed along the reference path and another portion of the reference beam which has travelled over a path of a fixed length is measured. The phase difference between the two portions of the reference beam and the phase difference between the two portions of the ranging beam are processed to determine the distance of the target from the ranging interferometer (70). The number of fringes resulting from the wave interference produced in the ranging interferometer (70) and the number of fringes in the wave inferference pattern produced by the reference interferometer (66) are counted and used, together with the knownlength of the reference path, to determine the distance of the target from the ranging interferometer (70). Very accurate range measurements may be obtained provided that the frequency deviation of the frequency modulation and the signal-to-noise ratio of the system is adequate. The surface roughness of the surface may also be ascertained by determining reflectivity profile (i.e. the intensity of radiation scattered by the surface of the target for a plurality of different angles of incidence of the beam), and speckle pattern (i.e. modulations in the scattered radiation produced by interference between radiation scattered by different points of the surface). The measured reflectivity profile and/or speckle pattern parameters may be compared with experimentally-obtained data for preder- mined surfaces of known surface roughness in order to approximate the surface roughness of the target.

Title: Liquid developing device
Inventor: KATO KEIJI
IPC: G03G15/10
Filed: 1986-03-10
Abstract: PURPOSE:To obtain a high-quality image having an extremely small irregularity in development and to perform development at a high speed by providing plural intake slits and plural outlet slits alternately and inserting a hollow pipe which has an opening for supplying a liquid developer inside and under the developer intake slits. CONSTITUTION:The liquid developer led to a development head is guided to hollow pipes 17 inside three intake slits firstly. The liquid developer led forcibly to the hollow pipes 17 is jetted through holes to strike on the internal wall under the intake slits 5. Holes are bored in the reverse sides of the hollow pipes so that the hole interval increases in the pipe lengthwise direction from the developer intake, i.e. the number of holes per unit length decreases. The liquid developer jetted from the hollow pipes passes through the gap between the internal wall of the outlet slit and the external walls of the hollow pipes and is led to the outlet slit exits while the amount and pressure are held constant in the outlet slit lengthwise direction, so that the liquid is supplied to a latent image surface. Thus, the developer is supplied uniformly in the breadthwise direction of the latent image.
