Title: Ozone generator
Inventor: TODA MASAYUKI
IPC: C02F1/78
Filed: 1994-04-13
Abstract: PURPOSE:To obtain an ozone generator designed to improve discharge tube cooling efficiency to raise ozone generation efficiency by providing the generator with a baffle having a gap-forming section and allowing cooling water flow from the outer periphery of one end of the axial direction of a grounded electrode tube to the outer periphery of the other end.

Also, because of setting up the baffle 11, the heat transfer area of a discharge tube can be enlarged significantly, thereby markedly improving discharge tube cooling efficiency and enabling input electric power to be increased safely and in high efficiency. Besides, since the baffle 11 has action to support the discharge tube, deflection of the discharge tube 4 can be obviated and the accuracy of a discharge gap 3 raised, esp. in a large-capacity type ozone generator with a long discharge tube.

Title: Cleaning method for semiconductor substrate
Inventor: HAYATA KAZUAKI
IPC: H01L21/304
Filed: 1990-03-23
Abstract: PURPOSE:To remove heavy metal on the surface of a substrate and to reduce the attachment of particles by maintaining cleaning liquid containing acid within a specified temperature range, and submerging a semiconductor substrate for a specified time. CONSTITUTION:Alkali cleaning is effective in removing particles, but heavy metal is hardly removed. In order to decrease the attachment of particles in acid cleaning, cleaning in a short time at low temperature is required. It is necessary to use cleaning liquid wherein particles are less in the liquid. From the viewpoint for removing the heavy metal, the temperature of HCl/H2O cleaning liquid is kept with in the range of 40-60 deg.C, and the substrate is submerged for 5-50 minutes. This cleaning method is optimum for cleaning the semiconductor substrate because the particles are not attached to the surface of the substrate and the heavy metal can be removed. In order to reduce the amount of the particles in the cleaning liquid beforehand, it is necessary to filter the cleaning liquid by using a required filter at least before the submergion of the substrate to be cleaned. It is also preferable that the cleaning liquid in a tank is circulated and filtered.

Title: Batten wind-up gear
Inventor: YAMAMOTO KIMISUMI
IPC: B65H19/28
Filed: 1979-06-14
Abstract: PURPOSE: To wind up a comparatively thicker batten in a coil which is free of elastic recovery over the whole range of the coil by winding up it in the coil form applying bending characteristics with a bending machine.  
     CONSTITUTION: When a comparatively thicker batten 8' is wound up, the central roll 10' of the bending machine 2' is an eccentric roll whose upper and lower eccentric rolls 12 and 13 are divided. The lower eccentric roll 13 transmits the counterforce of the bending moment applied to the upper eccentric roll 12 which contacts on the outer surface of the wound coil 7 and the battern 8' to the outer surface of the coil. Since the respective upper and lower eccentric rolls 12 and 13 do not engage their mutual rotation, the speed of the batten 8' is not restricted at the winding start and end. The length between the outer surface of the coil and the top of the roll can be reduced and bending characteristics be applied over the whole range of the batten 8'.
