Abstract: PURPOSE:To safely regenerate an etchant at a low cost by regenerating an etchant of ferric chloride by means of air oxidation. CONSTITUTION:In the main body 1 of air oxidation equipment consisting of a device 1a for removing mist, a spray 1b, a packing material 1c, an air blower 1d, a blast pipe 1e, a pump 4, etc., an etchant of ferric chloride is sprayed at about 60 deg.C via the spray 1b. Subsequently, air is fed from the air blower 1d to oxidize the etchant, and this etchant is moved into a chemical addition tank 2, where hydrochloric acid and water are properly and automatically added through a supply pipe 2e based on the values measured by means of an oxidation-reduction electrometer 2b, a specific gravity measurement sensor 2c, an acid concentration measurement electrometer 2d, etc., and the resulting mixture is agitated. This etchant is allowed to flow via a transport tube 5 into an etching device 3 and then circulated into the spray 1b in the main body 1 of the air oxidation equipment by means of the pump 4. By this method, etching can be safely and inexpensively carried out while keeping the concentration of ferric chloride at the prescribed conditions.

Title: Semiconductor memory and its test method
Inventor: KOUNO TOMOHITO
IPC: G11C29/50
Filed: 1995-03-27
Abstract: PURPOSE: To reduce the cost by detecting the short circuit of word line in a short time prior to die sort test thereby shortening the die sort time. CONSTITUTION: A plurality of word lines WL1-WLn are arranged in stripe on a memory cell array 13. Upon receiving a control signal CR from a pad 21, an address signal switching circuit 11 delivers an address signal for selecting every other word line in place of a normal address signal A. Consequently, a decoder 12 is alternately arranged with a word line being applied with a high potential and a word line being applied with a low potential. A detection circuit 14 detects the variation of potential owing to short circuit of at least one word line being applied with a high or low potential. Upon detection of potential variation, two detection pads 24, 25 are short-circuited.

Abstract: PURPOSE:To calmly execute the hysteresis action of an operating member with low price, and with a simple constitution without increasing greatly the number of parts by stopping the rotation of a rotary body when the engaging part of a movable member is located at the groove width having a large cam groove. CONSTITUTION:Even when the rotational angle of the second driving gear 66 is rotated reversely from 440 deg. and rotated exceeding 415 deg., the groove width of a groove cam 113 comes to be wider, the distance from a shaft 112 comes to be the same groove cam shape and at a cam follower 116, the force to shift the cam follower 116 from a groove cam 113 is not operated. Thus, the cam groove of the groove width is a constant groove width and larger than the constant groove width in a part is provided at the rotary body and the movable member follows the inner circumferential surface or the outer circumferential surface of the cam groove in accordance with the rotational direction of the rotary body. Thus, the hysteresis action of the operating member can be executed with low price, calmly and with the simple structure without increasing greatly the number of parts.

Filed: 1990-03-18
Abstract: PURPOSE:To improve the detection sensitivity, detection accuracy, and resolution and to realize low prices, size reduction, and high efficiency by using the X-ray optical fiber with which an X-ray fluorescent material is mixed for a core, and utilizing it for the detection of X rays. CONSTITUTION:The X-ray fluorescent material 9 is mixed in the core 7 of an optical fiber to constitute the X-ray fluorescent optical fiber. Incident light 5a from the end face and incident light 5b from the side face are mad incident on this fiber. Then the clad 8 is covered with a shield film 12 made of a material which X rays do not penetrate t make the X rays incident on the end face, or the end surface is provided with a shield film 13 and a window hole 14 is bored in the shield film 12 on the side face to make only either of the incident light beams 5a and 5b incident. Consequently, when the X rays are made incident to strike on the fluorescent material 9 in the core 7, visible fluorescent light 11 is emitted, and reflected and propagated in the core 7. This generated light is confined to the core 7 and transmitted in a detection direction, but diffused laterally so that the X rays can be detected with good efficiency.

Title: Rodenticidal tablet
Inventor: NAKASE TAKASHI
IPC: A01N25/08
Filed: 1980-05-21
Abstract: PURPOSE: A rodenticide is added to an animal or vegetable oil which is solid at room temperature and the mixture is used as a diluent and mixed with grains to produce rodenticidal tablets with remarkably increased activity.  
     CONSTITUTION: An animal or vegetable oil which is solid at room temperature and willingly eaten by rodents is used as a diluent to produce the rodenticidal tablets. Since the rodenticide is included in an animal or vegetable oil rodents which willingly eat, the rodents eat them more than grains, whereby the rodenticidal efficiency is largely increased. Conventional rodenticidal tablets contains a rodenticide-containing paraffin as a diluent; however, rodents bite the paraffine but do not eat it. Namely, the rodenticidal efficiency is low and many tablets are required for spreading out on the paths of rodents. The tablets of the present invention improve the defect.

Abstract: PROBLEM TO BE SOLVED: To keep the treatment capacity of a membrane separator by keeping the pH of raw water within a proper range, to prevent a pH sensor from being fouled, to detect pH correctly, and to facilitate control by detecting the pH of filtrate and injecting an acid into the raw water to keep the pH of the filtrate within a definite range. SOLUTION: The pH of filtrate is detected with a pH sensor 16 set in a filtrate line 9, an acid injection pump is actuated on the basis of the detected pH, and an acid is added from an acid storage tank 17 into raw water in a storage tank 6 to control the pH of the filtrate within a definite range. When the pH of the filtrate is above an upper limit value or is increased to the upper limit value, an acid injection pump 18 is driven. When the pH reaches a set value temporarily by the acid injection, the pump 18 is stopped. The above process is repeated to keep the pH of the filtrate within the definite range. In the detection of the pH of the filtrate, in order to minimize a difference in time from the pH of raw water, the detection is preferably carried out a in filtrate collection piping of a membrane separator 9.
