Title: Electrode forming device for electric discharge machining
Inventor: MIZUTANI TAKESHI
IPC: B23H7/22
Filed: 1986-07-16
Abstract: PURPOSE:To make it possible to machine a fine hole with a high degree of accuracy and to form a deep hole machining electrode having different cross-sectioned shapes, by forming the outer peripheral surface of an electrode forming block adapted to be subjected to electric discharge by an opposed electrode, in a circular shape so that the electrode forming block is rotated to facilitate the machining of the electric discharge surface of the block with a high degree of accuracy. CONSTITUTION:A power source 13 is turned on while an electrode 10 formed by a rotating means 11 is moved in the direction Xa, and an electrode forming flock 3 is rotated in the direction Xb by a rotary device 4. The formation of the electrode 10 in the longitudinal direction is carried out by moving the electrode 10 in the direction Ya by a drive means 12 while the lower surface of the electrode is opposed to the upper surface of the block 3. Further, when the electrode 10 is lowered so that the forward end of the electrode is located at a predetermined position where a predetermined electric discharge gap (d) with respect to the block 3 is obtained, electric discharge is started to perform a forming process. A diametrical forming process is carried out such that the electrode 10 is positioned at one side of the block 3, and is moved in the direction Yb by a drive means 12. Therefore when the space between the electrode 10 and the block 3 has come to be a predetermined electric discharge gap, electric discharge is initiated to carry out a forming process. With this arrangement it is possible to obtain the electrode 10 having satisfactory cylindricity and circularity, and it is possible to enhance the circularity when a fine hole is machined by electric discharge.

Abstract: PURPOSE:To produce a fermented milk containing gaseous carbon dioxide and ethanol and excellent in shelf life and flavor by adding glucose and fructose to a raw material and fermenting it in the presence of a Lactobacillus and a sucrose-nonanabolic microorganism belonging to Zymomonas mobilis. CONSTITUTION:To a raw material prepared by adding milk, skim powdery milk, unsalted butter, sugar, etc., to water and heating the resultant mixture under pressure and stirring so as to homogenize it, 0.25 to 2.5wt.% glucose and/or fructose is added. A Lactic acid bacterium (e.g. Lactococcus kuremoris) as a starter is inoculated thereinto and a sucrose-nonanabolic microorganism [e.g. Zymomonas mobilis subsp. pomaceae (ATCC 29192)] belonging to Zymomonas mobilis is further added thereto. The raw material is fermented in one step or stepwise by allowing both the microorganisms to simultaneously act or by initially allowing the Lactobacillus to act and then allowing the sucrose-nonanabolic microorganisms belonging to Zymomonas mobilis to act. Thus, the objective fermented milk containing a suitable amount of carbonic acid and low-concentration ethanol can be produced.

Filed: 1992-06-25
Abstract: PURPOSE:To prevent the possibility of giving an adverse effect on the base material where a wiring material is not deposited, although a method of filling connecting holes by radiating the excimer laser, leaving the wiring material only in the vicinity of the connecting holes has been proposed. CONSTITUTION:A lower layer wiring 12 is formed on a semiconductor substrate via an insulating film 11, an interlayer insulating film 13 is formed thereon and thereafter a through hole is opened. Next, TiW 14 and aluminum alloy 15 is coated on the entire surface (a). Next, the aluminum alloy 15 is removed from the area other than that in the vicinity of the through hole is removed (b). Thereafter, the aluminum group alloy 15 is melted by the application of an excimer laser and thereby the though hole is filled with aluminum alloy 15 (c). The laser does not transmit through the interlayer insulating film 13 by leaving a metal which is comparatively difficult to melt like TiW 14 on the entire surface. As a result, the through hole may be filled without giving any influence on the lower layer wiring 12.

Filed: 1985-07-30
Abstract: PURPOSE:To reduce an error rate against the damage or the defect of a medium by setting the recording frequency in the recording of management information at a management area lower than the one in the recording of the information at an information recording area. CONSTITUTION:Inputted information through an interface 1 is error-corrected and encoded at an error correction circuit 3 and is recorded on an optical disc D. At such a time, it is assumed that, in the recording from a buffer 2 to a circuit 2, a fundamental clock frequency when the recording on an information recording area D2 is performed is set as (f) and the fundamental clock frequency in the recording on a management area D1 using a transfer fundamental clock switching circuit 11 is set as a value lower than (f). When the same signal is recorded with (f) and (f)/3, a reproduced sampling frequency become (f) and (f)/3. In this case, a window become T and 3T. At such a time, assuming that the medium defect of length T on the disc D is existed, a reproducing error is not generated when the window width is recorded with 3T. Therefore, the lower the recording frequency by which the recording performed on the area D1, the lower the rate of the reproducing error.

IPC: G01M3/16
Filed: 1985-07-31
Abstract: PURPOSE:To quickly detect a leaking liquid in an optional section with a simple constitution, by transmitting detecting commands by commanding detection- required sections to terminals provided at every section. CONSTITUTION:Each terminal B is cascade-connected with a command monitor A through transmission media C. A section sensor D which detects presence of a leaking liquid in its own section is connected with each terminal B. When a signal arrives to each terminal B from the monitor A through the transmission media C, the signal is inputted to a control circuit P through a receiving circuit R. When the signal is the detecting command addressed itself, the control circuit P designates a measurement circuit S to measure presence of a leaking liquid in its own section and transmits the measured results to the command monitor A through modulating transmission circuit Q. Therefore, an optional section can surely be detected in a short time under a concentrated condition.
