Inventor: SHISHIDO HIROSHI
IPC: A47J37/12
Filed: 1995-03-16
Abstract: PURPOSE: To save oil through the frying with an appropriate and minimum necessary quantity of vegetable oil by deoiling the prefried food in an overheated steam ambience produced by a low-pressure and high-temperature overheated steam generator. CONSTITUTION: A food carrying conveyer 3 is arranged inside the body 2 of low-pressure and high-temperature overheated steam generator 1 and in its upper part, an exhaust outlet 5 of overheated steam and radial atomization outlet 6 of vegetable oil are also arranged. The exhaust outlet 5 and overheated steam-generating boiler 7 are connected by a steam- conducting pipe 8, while the radial atomization outlet 6 of vegetable oil and vegetable oil tank 9 are connected by an oil-transfer pipe 11 through an oil-transfer pump 10. Moreover, the oil-collecting plate 4 is provided with an oil collector 12 in its lower part. Thus, the saturated steam to which heat is added, i.e., the overheated steam transfers the heat of thermally radial gas produced by the convection and radiation.  Therefore, the frying with an appropriate and minimum necessary quantity of vegetable oil weakens the oxidation of oils and fats by surplus oil layer covering the food. Meanwhile, it promotes the recycling of oil, effectively saves oil, enables the frying with an appropriate and minimum necessary quantity of vegetable oil, and makes the product surface not too much oily.

IPC: F16G5/16
Filed: 1989-04-13
Abstract: PURPOSE:To make the assemble of a hold strap simple by making the hold strap out of a shape memory alloy which makes a clockwise cross section into a flat shape, using the hold strap which is made narrow in width, at the time of assembly, and thereby restoring it into one in a flat shape stored in advance thereafter by means of change in temperature. CONSTITUTION:A V-belt 10 is composed of plural numbers of belt straps 11 in a flat plate shape in a clockwise cross section, and of a metallic block 15 which is slidably mounted onto said straps. A hold strap 13 is mounted onto fitting grooves 18 and 18 provided at the both sides of a strap arrangement groove 17 so that the metallic block 15 does not come out of the belt straps 11. Since the hold strap 13 however, has to be wider in width than the arrangement groove 17, it is quite hard to install it as it is. In this case, the hold strap 13 is thereby made out of a shape memory alloy wherein it is interposed into the arrangement groove 17 while it is made narrowed in width after being deformed into an arch form, it is restored to a shape stored in advance by heating or cooling it thereafter.

Title: Evaluation method of silicon wafer and silicon wafer with excellent pressure proof characteristic of oxide film
Inventor: UMENO SHIGERU
IPC: G01N21/94
Filed: 1995-03-27
Abstract: PURPOSE: To make possible the accurate measurement of the density of a defect with an arbitrary width by performing a multi-layer measurement varying the depth of an observation visual field parallel with the surface of a wafer. CONSTITUTION: A multi-layer observation is performed moving an observation visual field in the direction of the width at such a pitch that the most of defects within the observation visual field can be observed being overlapped. The size of signals equal or closer in coordinates on an observation visual field plane of a defect is plotted in every layer with respect to the depth of the observation visual field to allow judging of whether a signal source exist within an observation area or not. As a result, the signal owing to a defect, or a flaw and foreign matters on the surface or rear outside the observation area can be removed.  For example, by an infrared phase microscope method, the multi-layer observation is performed moving the observation visual field by 2μm in the direction of depth to plot the size of signals in all layers with respect to the depth of the observation visual field. The segment ab is within the range of the depth allowing the observation of the defect when a threshold is 1.0V and the maximal point (c) of the size of the signals reflects the width at which the defect exists and the size of the defect.

Title: Etching method for semiconductor substrate
Inventor: OKABE YUTAKA
IPC: H01L21/76
Filed: 1986-04-24
Abstract: PURPOSE:To prevent a stepwise difference and a bowling from occurring in a trench by employing a mask having a window of the shape sequentially expanding outside from the surface of a mask toward the surface of a semiconductor substrate in an area of a window parallel to the surface of the substrate. CONSTITUTION:The inner wall of a window is dry etched under etching conditions of strong directivity to a semiconductor substrate 31 from above a reversely tapered mask pattern 41. Even when the mask layer 41 is etched and deformed, edge portions 39a always cover the exposed surface of the substrate in an overhanging state. Thus, the inner wall of the window 39 of the layer 41 remains reversely tapered shape. In this manner, since the inner wall of the window 39 is less directly contacted with etching ions, the abrupt film reduction of the layer 41 does not occur in a direction parallel to the surface of the substrate to eliminate a stepwise difference and a bowling on the inner wall of a trench to obtain a tapered trench 45.

Title: Drink canning method
Inventor: TAMAOKI YOJI
IPC: B65B31/00
Filed: 1988-04-20
Abstract: PURPOSE:To reduce the remaining oxygen amount in the upper space of a can and at the same time, maintain the vacuum degree in the can in a predetermined range, by filling a drink in a metal can while leaving an upper space, and sealing the can after substituting the air in the upper space with a mixed gas of nitrogen gas and steam with a specific partial pressure ratio. CONSTITUTION:A heat pasteurized drink is filled in a metal can, e.g., aluminum can or tin can, etc. Then, in an upper space of the can, a mixed gas of nitrogen gas and steam is blown in, and the can is sealed after the air has been substituted with the mixed gas. The partial pressure ratio of nitrogen gas to steam in the mixed gas is 4:1 or 1:1. If the ratio of nitrogen gas is higher than this, it is difficult to make the vacuum degree in the can higher than 30cm Hg, and if the ratio is lower than this, it is difficult to reduce the remaining oxygen amount sufficiently. The blowing in of the mixed gas of nitrogen gas and steam can be performed by the same method with the traditional steam blowing. The sealing of the can after substituting the air with the mixed gas is performed by an ordinary method, e.g., using a double rolling machine to seal.
