Filed: 1986-04-18
Abstract: PURPOSE:To omit a masking process, by providing a device for pushing a semiconductor substrate in a reacting chamber, and etching only the back surface of the substrate without applying a mask scuh as resist on the surface of the substrate. CONSTITUTION:In a transparent reacting chamber 1, a pair of electrodes 2 are arranged at the upper and lower positions. Semiconductor-substrate mounting devices 6 comprising three or more insulators are arranged on the peripheral part of the lower electrode at an equal interval. A semiconductor substrate 3 is mounted on the devices 6. Etching gas is introduced in the chamber 1. The gas in the chamber 1 is reduced with a pump. A high frequency voltage is applied to a pair of the electrodes 2. Then, glow discharge is generated, and plasma is yielded.

Title: Dewatering under pressure in filter press
Inventor: SHIBASAKI TOSHITAMI
IPC: B01D25/12
Filed: 1983-05-19
Abstract: PURPOSE:To obtain the cake having a desired water content of cake by measuring each pressure of a pressure chamber, a filtration chamber, and the filtrate side, and stopping the dewatering under pressure when the measured value reaches a specified value. CONSTITUTION:The sending of the original water under pressure is stopped when the filtration is not practically carried out due to the successive accumulation of a solid constituent on a filter cloth 13. As a pressurized fluid is sent into a pressure chamber 15 from a pressure entrance and exit 7 of a pressurizing apparatus A, the second piston (presser plate) 6 moves backward to squeeze the cake filling a filtration chamber 14 which is filtered by a filter cloth 14. The filtrate is discharged from a filtrate discharge port 10, and the cake contg. a low water content is obtained simultaneously. In this pressurizing operation, when the pressure P2 is exerted onto the pressure chamber 15, the second piston 6 moves backward and the pressure of the filtration chamber 14 decreases gradually, and further decreases with the progression of the solidification of the cake to the pressure P1. The cake having a desired water content can be obtained when P2-P1 attains to a prescribed value.

Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To enable the simple and easy preservation of vegetables and fruits, etc., in high quality, minimization of the amount of a packaging material used and reduction in disposal cost according to a specific packaging method. SOLUTION: The whole surface of a food is initially coated with an aqueous solution containing alginic acid and a water-soluble compound such as pullulan and the resultant film is then brought into contact with an aqueous solution of a polyvalent metallic salt, e.g. calcium chloride to insolubilize the alginic acid and provide a coating film. The resultant food coated with the coating film is subsequently brought into contact with water to dissolve the water-soluble compound in the water. Thereby, the gas permeability of the coating film is regulated to package the food. The alginic acid is converted into an aqueous solution containing the alginic acid dissolved in an acid or an alkali, e.g. an aqueous solution of sodium alginate and the concentration thereof is regulated to 0.5-6wt.% for use.

Title: Heat exchanging section of double-wall structured heat exchanger
Inventor: AKACHI HISATERU
IPC: F28D7/10
Filed: 1987-04-14
Abstract: PURPOSE:To provide a compact, light-weight and high-performance heat exchanger by forming a spiral flow passage for fluid by disposing a spiral fin having a suitable pitch which tightly contact the inner surface of an outer pipe and the outer surface of an inner pipe and extends axially along side walls. CONSTITUTION:By a combination of an outer pipe 1, an inner pipe 2 and a spiral fin, a spiral passage 4 is formed between the inner pipe 2 and the outer pipe 1. By causing the outer thermal medium 9 and inner medium 10 to flow, heat is exchanged through the pipe wall of the inner pipe 2 by making one of them to be a high- temperature fluid and the outer a low-temperature fluid. This way, the section area of the flow passage between the outer pipe 1 and the inner pipe 2 is made more than ten times smaller, and the flow speed is made more than ten times faster. The smaller the spiral pitch, the larger the heating surface of the flow passage. When the flow speed becomes faster, turbulence is caused in the flow to improve the heat transfer performance, and so, it is generally expected that there will be about ten times more improvement. The heat exchanging section by the double-walled pipe can be economically manufactured, and the device can be made compact with a high performance.
Patent JP-S61248047-A (JP)
Title: Heat development control device
Inventor: NAKAUCHI KENJI
IPC: G03D13/00
Filed: 1985-04-25
Abstract: PURPOSE:To improve the responsiveness of a heating temp. to a target value by determining the current value or voltage between terminals of an electrical heating element as a feedback quantity when the specified value of the voltage between terminals of current of said element is detected. CONSTITUTION:The resistance value R increases when the temp. of the electrical heating element 14 exceeds the target value. Then the current value flowing in the element 14 decreases and the absolute values of a supply current signal I and current signal IR corresponding to the resistance value decrease, resulting in an increase in the value of a phase control signal PC. The shortened pulse width of a gate trigger pulse GP, the decreased firing angle of a triac 12, the decreased average voltage between terminals of the element 14 and the decreased current flowing in the element 14 are therefore resulted, by which the temp. of the element 14 is decreased so as to approach the target value. The operation reverse from the above-mentioned operation takes place when the target value of the element 14 decreases down to the target value or below. The temp. of the element 14 is thereby brought near to the target value. The temp. of the element 14 is thus maintained at the target value.

Title: Image binarization device
Inventor: ISHIDA AKIRA
IPC: H04N1/46
Filed: 1993-04-16
Abstract: PURPOSE:To convert a color value image recorded in color representation of a uniform color space, into binary data by finding a binary output value and correcting an error after a color value correcting means corrects the color value of a reference pixel of the color value image. CONSTITUTION:The color value correcting means 12 corrects the color value 16 of the reference pixel of the color value image recorded in the color representation of the uniform color space. An output value retrieval means 13 finds the binary output value 19 to an output device and an error quantity calculating means 14 calculates the difference between the color value 17 after the correction of the reference pixel and the color value 19 corresponding to the binary output value. While an error value adding means 15 divides and adds the difference as an error 21 to pixels at the periphery of the reference pixel which are not set as a reference pixel so far, the position of the reference pixel is moved in the order of the main scanning and subscanning of the color value image to perform the binarization of the color value image. An output image which is faithful to an inputted color value can be obtained without temporarily converting the color value image, recorded in the color representation of the uniform color space, into a CMY or CMYK value in color representation characteristic to the characteristics of the output device.
