Title: Removing method for metal impurity from semiconductor wafer cleansing chemicals
Inventor: OKI ICHIRO
IPC: C02F1/62
Filed: 1993-01-28
Abstract: PURPOSE:To enable metal impurities to be easily removed from dilute hydrofluoric acid or buffer hydrofluoric acid by a method wherein a process wherein silicon wafers are dipped into dilute hydrofluoric acid or buffer hydrofluoric acid and taken out of it is repeatedly carried out to enable metal impurities contained in these chemicals to be attached to the silicon wafers and then removed from the wafers. CONSTITUTION:Buffer hydrofluoric acid 101 contaminated with Cr is poured into a Teflon tank 102. A process, wherein a Teflon cassette 103 in which four silicon wafers 104 are housed is dipped into buffer hydrofluoric acid 101 filled into the Teflon tank 102 and taken out of it by moving the cassette 103 up and down, is repeatedly carried out 500 times in a five-second cycle, two seconds for dipping, one second for drawing out, one second for holding in air, and one second for descending. Thereafter, the silicon wafer 104 is taken out of the Telfon tank 102. Cr contained in buffer hydrofluoric acid can be more efficiently removed by this method as compared with a conventional method wherein five silicon wafers are dipped into buffer hydrofluoric acid for the same time.

Title: Optical path branching filter
Inventor: KITAGISHI NOZOMI
IPC: G02B27/10
Filed: 1979-02-07
Abstract: PURPOSE: To achieve the miniaturization of the optical path branching filter by installing the exit surface of the optical block from which the light reflected by a half mirror is emitted, in nearly parallel to the luminous flux reflected by a total reflecting mirror.  
     CONSTITUTION: The luminous flux A from a condenser lens is divided to the transmitted luminous flux B and reflected luminous flux by a half mirror 7. This reflected luminous flux is made to the luminous flux C by a total reflecting mirror 8 and is entered to a photometric element 10. Here, the surface 11a of an optical block 11 from which the luminous flux going toward the mirror 8 is installed nearly parallel to the luminous flux C. Then, the stray light D, which tries to enter the phtotmetric element directly without being reflected by the mirror 7, out of the light of the luminous flux A, enters the surface 11a by having a large angle θ and therefore it is totally reflected, thus the cutting off of the luminous flux C and stray light D is distinctly accomplished. This makes it possible to reduce the spacing of the luminous fluxes B, C and miniaturize the optical path branching filter.

Both the frame body 10 and the magnet holders 11 are constituted by magnetically permeable materials and act as a york. Therefore, the N-S opposed magnets 50 are surrounded by the york at their periphery and the reverse magnetic fields projected from the N-S opposed magnets 50 are absorbed and attenuated by the surrounding york, so that the vertical magnetic field can be expanded and a base film 2 having an undried coating film 4 is prevented from bad influence due to the reverse magnetic field at the time of charging/ discharging between the opposed magnets 50. Consequently, magnetic particles in the coating film 4 are properly oriented in the vertical direction and the orientation is properly held.

Title: Image forming device
Inventor: KIMURA YOICHI
IPC: G03G15/00
Filed: 1994-01-11
Abstract: PURPOSE:To minimize the rise time of a transfer electric field, to stably carry a recording material and to obtain an excellent image by changing the feeding output of a transfer electrostatic charge means on the recording material. CONSTITUTION:A transfer current is supplied from a high-voltage power source according to the value of a control signal transmitted from a DC controller so as to give an output to the transfer electrostatic charger. However, when the signal corresponding to a fixed current 107muA such as the control signal B is given to the high-voltage power source, the rise time (deltat') is generated for the actual transfer electric field because of the impedance of the transfer electrostatic charger, a recording material carrying sheet (f) and the recording material 200. Then, the signal corresponding to the current 15muA which is larger than the desired fixed current 10muA such as the control signal A is transmitted in a short time at the rise time and the signal corresponding to the desired fixed current 10muA is given thereafter. By shortening the rise time (deltat) of the transfer electric field by such a way, an area on which the transfer electric field is not impressed is increased at the marging width or the recording material 200 and the recording material 200 is stably carried.
