Title: Electric dust collector
Inventor: BASE SHIGEKI
IPC: B03C3/72
Filed: 1992-08-27
Abstract: PURPOSE:To obtain a device in which spark discharge will not continuously occur more than predetermined times and which does not require the EP constantly changing in the conditions of producing the spark discharge to be readjusted in the preset value of the spark discharge frequency. CONSTITUTION:A control device 10 is provided with a VC limiter adjusting means for producing the limiter operating value which decreases by a predetermined control value, then increases and after the lapse of a predetermined time returns to the original one when EP 9 produces spark discharges continuously predetermined times in order to control capacitor voltage to charge a capacitor 6 through a low tension AC power controller 2, whereby the continuous occurrence of spark discharge can be prevented, particularly in the case of a small pulse frequency. Even when the EP conditions of producing spark discharge are changed, there is no need for readjusting the preset value of the spark discharge frequency, the application to EP 9 of the maximum voltage is always possible and unnecessary charge control is avoided upon a sporadic spark discharge to control the lowering of the dust collecting performance.

Title: Treatment of reverse osmosis membrane and reverse osmosis membrane separation element
Inventor: OKAZAKI MOTOHIRO
IPC: B01D65/06
Filed: 1993-09-14
Abstract: PURPOSE:To prevent the elution of impurities from a membrane separation element by washing a reverse osmosis membrane and a separation element constituting member with org. solvent. CONSTITUTION:As a reverse osmosis membrane, a dual type reverse osmosis membrane obtained by forming a functional membrane layer taking charge of separation on a perforated support by interfacial polycondensation reaction, cross-linking reaction, polymer coating or a monomer polymerization is used. A membrane separation element to be used is constituted by incorporating the reverse osmosis membrane along with other member. An org. solvent such as lower alcohol, ethers or ketones or a mixture of two or more kinds of solvents is used to prepare an aq. soln. and a reverse osmosis membrane and a separation element are immersed in the aq. soln. for a predetermined time. Whereupon, the residual monomer component being the unreacted substance of interfacial polycondensation forming a functional membrane layer is eluted to rapidly desorb the org. meter bonded to or adsorbed on the permeation side of the membrane separation element. The washing due to the org. solvent is effective for removing an org. amine component and an org. chloride component and has effect for reducing the concns. of both of an ionic substance and a TOC component.

Title: Foreign matter inspecting device for wafer
Inventor: JINGU TAKAHIRO
IPC: G01N21/956
Filed: 1991-08-14
Abstract: PURPOSE:To make sensing of foreign matters over the whole surface of wafer by furnishing an edge foreign matter sensing means to sense foreign matters attached to the peripheral edges of a wafer and the inter-IC chip edge parts, producing a photo-receiving signal for the diffusive light at the edge parts, and sensing existence of foreign matters through comparison of the photo- receiving signal with the threshold. CONSTITUTION:When a wafer 1 is scanned with a laser beam Lx, a position signal exhibiting the X-Y coordinates for the scanning position is emitted and fed to a control signal generation part 5a, which issues control signals Cr, Ck. The control signal Cr corresponds to the coordinates Xs, Xt for intersections s, t of the laser beam Lx with the chip outsides at two ends while the control signal Ck corresponds the coordinates Xr, Xu for intersections r, u of the laser beam with the wafer periphery 1a. Threshold Ve and chip threshold Vth are stored in a threshold register. The differential data from a differential circuit 4c is subjected to comparison, and foreign matters in the chip are sensed. Thus, sensing of foreign matters over the whole wafer surface is made practicable by furnishing a simple foreign matter sensing means applicable to the edge parts as embodied in the structure as described above.

Title: Milling method
Inventor: USAMI MORIKAZU
IPC: B02C13/12
Filed: 1990-08-30
Abstract: PURPOSE:To obtain uniform fine powder by turning and moving a raw material in a grinding chamber and pulverizing the raw material by the difference of moving velocity between particles accompanied with turning movement. CONSTITUTION:When the respective rotary blades 4, 5 are rotated by a driver via a driving shaft 6 and a driving cylinder 7, the air in a grinding chamber 3 becomes a turning flow by action of the rotary blades 4, 5 and is transferred in the inside of the grinding chamber 3. In this state, when a raw material is introduced into a main body frame 1 through an introduction port 2, the raw material (a) is introduced into a grinding chamber 3 through the first rotary blade 4 and moved in the grinding chamber 3 by action of the turning flow. Velocity difference is caused between the raw material in the center side of the turning flow and the raw material in the outside. Friction is caused between the raw materials with each other and thereby fine powder is produced. Thus, grinding efficiency is made excellent and further distribution of powder diameter is freely set.

Abstract: PURPOSE:To obtain an inexpensive system by splitting a locker arm into cam side arm and valve side arm while providing a plunger on one arm for energizing to contact against the other arm thereby enabling change between slide and fix by means of a slide lever. CONSTITUTION:A solenoid (not shown) is not functioned under heavy and intermediate load area of engine, so a drive sleeve 19 is moved to the right by a spring 18 to engage the stopper hole section 23a of exchange hole 23 in lock- off plate 16 with engaging section 22 formed at the end of plunger 14 while reducing the diameter thus to fix the plunger 14. Then the cam side arm 11 and valve side arm 12 of locker arm 9 are jointed integrally to open/close the valve through rotation of cam shaft. While under low load area, the solenoid will function to move the plate 16 to the left through the drive sleeve 19 thus to allow sliding of plunger and to rotate both arms 11, 12 relatively to disable the valve.

Title: Protective circuit for surge of semiconductor switch
Inventor: KATO TATSUYA
IPC: H01L27/088
Filed: 1983-12-06
Abstract: PURPOSE:To protect a switch completely from a surge by separately forming voltage as a reference flowing out the surge through a diode. CONSTITUTION:When a positive surge larger than supply voltage VCC is applied to an input-output terminal 11 for a switch 13, the forward voltage drop VF of a diode 15 and the Zener voltage VZ of a Zener-diode 20 are set to values lower than supply voltage VCC only by a value lower than the value of the forward voltage drop VF of the diode to the input-output terminal 11. Consequently, overvoltage is not generated at the terminal 11. When a negative surge is applied to the terminal 11, on the other hand, surge currents flow through the terminal 11. The potential of the terminal 11 is not made lower than common potential because the potential of an emitter in a transistor 23 is fixed at the forward voltage drop VF of the diode at that time. Operation at a time when the positive or negative surge is applied to an input-output terminal 12 is also made the same as the terminal 11.
