Title: Cooker
Inventor: TAKAYAMA ATSUSHI
IPC: A47J43/046
Filed: 1993-03-18
Abstract: PURPOSE:To prevent an air hole from closing and stop a motor immediately when a hand is released from an operation by providing an operating case with a rib abutting against a projection entering an operating hole, a blast path communicating with the air hole and a lid to locate a receptacle. CONSTITUTION:A rib 75 of an operating case 70 is adapted to abut against a lid 60 to locate an operating projection 73, and a rib 74c of the side wall of an operating section 72 is adapted to abut against the side of a projecting part 50a of the projecting section 50 to cover the lid 60 and projecting section 50 with the operating case 70. Thus, the operating projection 73 enters an operating hole 51. When the operating case 70 is pressed from above, the operating projection 73 shifts an operating rod 52 downward against a spring 53 so that a switch 54 is turned on to drive a motor 21. Since a leg part 24c is placed below the projecting section 50, a main body 20 is prevented from sinkage by the leg part 24c having no elastic force. Hence, the satisfactory responsive property of the switch 54 is obtained. Also, even if gas flows out in cooking, the gas flows from an air hole 65 in the lid 60 through a gap 80 and blast path 83 to the outside to prevent a stirring effect from reduction due to high pressure.

Title: Metallic pipe for metallikon
Inventor: HAJIKANO KIYOSHI
IPC: C23C4/06
Filed: 1982-04-09
Abstract: PURPOSE:To enhance the corrosion preventing effect of sprayed layer formed by metallikon by filling fine grains of ceramics into a metallic pipe for Metallikon and by using the pipe in the formation of an anticorrosive sprayed layer. CONSTITUTION:Fine grains 2 of ceramics having 30-300mum grain size are filled into a metallic pipe 1 of a conventional metal for metallikon such as Pb, Zn, Al, Sn or Cu, and the diameter of the pipe 1 is reduced with dies, a roller or the like to form a metallic wire for metallikon. The wire is used in place of a metallic wire for metallikon for anticorrosive coating. A sprayed layer of fine grains of ceramics coated with the metal for metallikon is formed, so the corrosion preventing effect of the sprayed layer is maintained over a long term.

Title: Electromagnetic flowmeter
IPC: G01F1/58
Filed: 1992-03-17
Abstract: PURPOSE:To accurately measure the flow rate of a fluid to be measured even when a measuring pipe is not filled up with the fluid by arranging a cylindrical body made of a material having electric conductivity which is nearly equal to that of the fluid and provided with a plurality of through holes in the axial direction of the measuring pipe in the measuring pipe so that the cylindrical body can be brought into contact with electrodes. CONSTITUTION:In the title flowmeter 11, such a condition that a a measuring pipe 12 is filled up with a fluid to be measured can be created when a cylindrical body 15 made of a material having electric conductivity which is nearly equal to that of the fluid and provided with a plurality of through holes 14 in the axial direction of the pipe 12 is arranged in the pipe 12 so that the body 15 can be brought into contact with electrodes 13. Therefore, while the number of through holes 14 which are passed through by the fluid changes depending upon the level of the fluid, the flow rate of the fluid passing through each hole 14 accurately generates an interelectrode electromotive force due to the weight-function magnetic flux distribution of the flowmeter 11. As a result, an accurate flow rate indication can be obtained even when the pipe 12 is not filled up with the fluid to be measured.

Title: Fine pattern formation method
IPC: H01L21/027
Filed: 1992-03-17
Abstract: PURPOSE:To make it possible to form a fine resist pattern with high dimensional accuracy by specifically changing the film thickness of a resist film during exposure. CONSTITUTION:Exposure light 3 is selectively emitted to a resist 2 coated on a semiconductor substrate 1 while laser light 5 is emitted from a slanting direction at the same time. A wavelength which does not expose the resist 2 to light is selected for the wavelength of the laser light 5 used here. Furthermore, the laser light 5 is scanned by means of a mirror 6 all over the exposure area. Assuming that the refraction factor of the resist film 2 is (n) and the exposure wavelength is lambda, the film thickness of the resist film 2 during exposure is caused to change by lambda/2n and over. In this manner, wafer heating reduces the film thickness of the resist film 2 and chancels the periodic dimensional accuracy of resist patterns, which makes it possible to form a fine resist pattern with high dimensional accuracy.

Title: Sheet carrying device
Inventor: NAKADA TADAYOSHI
IPC: B41J13/08
Filed: 1986-03-17
Abstract: PURPOSE:To prevent the unstable traveling condition due to the increase of the thickness of sheet by providing a rotary sleeve contacting against the outer circumference of second drive roller for driving a belt which carries a sheet held between a first drive roller. CONSTITUTION:A sheet 2 is driven by means of a first drive roller 1 and when the thickness of the sheet is relatively small, it is driven by a second drive roller 4 through a rotary sleeve 6 and a carrying belt 3. The driving torque of the second drive roller 4 is transmitted frictionally to the rotary sleeve 6 so as to drive the carrying belt 3. When the thickness of the sheet 2 is increased thereby the tensile force of the carrying belt is increased, the load of the second drive roller 4 is increased and when it has exceeded over a limit, a slip is produced between the second drive roller 4 and the rotary sleeve 6 so as to reduce the friction. Consequently, the sheet 2 is driven only by means of the first drive roller 1 thus stabilizing the travel.
