Title: Sheet multiple feed preventive device
Inventor: NISHIBORI TOSHIKI
IPC: B65H3/46
Filed: 1982-02-13
Abstract: PURPOSE:To make document sheets feedable piece by piece without any damage to each individual document, by installing both a document sheet suction device and a multiple feed preventive document sheet suction device, while making vacuum attraction of the latter smaller than that of the former as well as making it larger than suction force between pieces of copying paper. CONSTITUTION:When a document sheet 25 is fed, first a paper feeding table 23 is made to go up, then the document sheet 25 on the topper among a plural piece of document sheets 25 mounted on the table is attracted to the suction port of a document sheet attractive device 21 and a document sheet 25' is rendered going up to a paper feeding position. Next, a document sheet suction device J for multiple feed prevention use is set in vacuum motion and its suction port is drawn back after being advanced to the extent of sticking to the reverse side of the topper document sheet 25. At this time, attractive force of the device J is set to be smaller than that of the device 21 as well as to be larger than suction force between pieces of copying paper. And, when a plural piece of document sheets 25 are sucked to the device 21, the second place document sheet and downward ones are separated by means of vacuum suction action of the device J.

Title: Manufacture of inductance element
Inventor: TAKAHASHI TETSUO
IPC: H01F41/04
Filed: 1987-02-03
Abstract: PURPOSE:To provide a high inductance in an inductance element by printing a first electrically insulating layer with electrically insulating paint, further forming second and third electrically insulating layers, repeating the steps until a desired laminate is obtained, and then baking it. CONSTITUTION:Conductive paint is so printed and dried as to obtain a semicircular metal pattern 3 having a terminal 2 on an insulating layer 1 printed on a plastic base. Then, electrically insulating paint is printed on the whole surface except one end of the pattern 3 and the terminal 2 to form an electrically insulating layer 4. The paint is printed, one end of a new metal pattern is overlapped on the end of the pattern 3 exposed in the hole 5 of the layer 4, and an insulting layer 8 is printed by the same paint except the hole 7 to expose the other end of the pattern 6, after drying. A semicircular metal pattern 9 is printed on the layer 8, and dried to form a coil of a half of one turn. Thus, an inductance element which can be utilized as a transformer is obtained to increase the inductance value by utilizing a ferromagnetic material.

Title: Semiconductor device
Inventor: FUKUDA HIROSHI
IPC: H01L29/78
Filed: 1984-02-10
Abstract: PURPOSE:To enlarge the diffused layer surrounded by a gate electrode, and to prevent the lack of gate insulation film in the photoetching process by a method wherein the gate electrode is shaped into a square framelike form, and a corner of the gate electrode is bent at an angle of 90 deg. or more to a straight line section of the gate electrode. CONSTITUTION:The gate electrode 31 forms almost a square frame and locates one side 41 on an SiO2 layer 32 and the other side 42 in a P-well 30. The reason why one side 41 is located on the layer 32 is to improve the static withstand voltage by taking the area of the diffused layer 35 on the side of an input circuit occupied in the well 30 as wide as possible. Besides, formation of the gate electrode 31 in square frame like form is likewise to take wider the area of the layer 35 in the well 30. The corners 43 and 44 of the gate electrode 31 are bent at an angle of 90 deg. or more to the straight line sections 41, 42, 45, and 46, thus improving the adhesion property with photo resist.

Filed: 1983-02-15
Abstract: PURPOSE:To provide the titled compsn. which can moderately adhere to objects to be coated and can be easily peeled off after coating, but does not cause the peeling-off of a coating film at the time of the peeling of the compsn., by dispersing tetra-fluoroethylene telomer in an org. solvent. CONSTITUTION:A compsn. for masking is obtd. by dispersing tetrafluoroethylene telomer (e.g. one having a number-average MW of 1,000-500,000) in an org. solvent such as 1,1,2-trichloro-1,2,2-trifluoromethane. This compsn. for masking has moderate adhesion, so that there is no fear of the compsn. dropping out of itself and the compsn. can be easily peeled off by a nail, etc. after coating. A surface masked by the compsn. is non-adherent to paints, so that there is no fear of a coating film being peeled off at the time of the peeling of masking. When a silicone water repellent, a fluorine-contg. water and oil repellent, a parting agent or a surfactant is used together, masking can be mach easily peeled off in the case of coating of baking type paints.

Title: Wiper device
Inventor: YAMAMURA TADAYOSHI
IPC: B60S1/08
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To prevent a fusing damage of a relay contact by providing a holding control circuit for holding a movable contact of a wiper relay in an abutting state corresponding to the driving position immediately before change-over of a wiper switch when the wiper switch is put among plural driving positions. SOLUTION: In the case where a wiper switch SW 30 is changed from LO postion to INT position, when the wiper SW 30 is simply put in the off-state between the LO position and the INT position, a battery current is continuously earthed from a movable contact through an earth contact. Thus, a movable contact 44 of LO relay 40 is held on the ON contact 48 side (in an butting state corresponding to the driving state before switching), and a wiper motor 12 continues to be operated at low speed. Accordingly, the disadvantage that a braking current flows through the movable contact 44 and the OFF contact 46 and then discharge occurs across the contacts can be eliminated, so that fusing damage of the movable contact 44 and the OFF contact 46 can be surely prevented.

Title: Method for scarfing metallic slab
Inventor: MIYOSHINO YASUHITO
IPC: B23K7/10
Filed: 1994-01-27
Abstract: PURPOSE:To prevent a banded ruggedness from generating on a scarfing surface by arranging plural discharging nozzles on the surface of a slab and, in scarfing the surface layer of the slab by the flame jetted from the holes, shifting the arranging direction of the holes for a prescribed angle from the axial direction in the width of the slab. CONSTITUTION:A line of discharging nozzles 2 is arranged with a shift by a prescribed angle for a width direction axial line 4. With this state maintained, scarfing is performed by the flame 7 while the line of discharging nozzle 2 is moved in the longitudinal axial line 5 of the slab 1. The prescribed shifting angle 6 for the line of discharging nozzles in this case is determined by using an inequality, tantheta>=W/L, based on the width of those raised parts (higher parts) on the scarfing surface of the slab that would be caused in the middle in between the discharging nozzles due to an insufficient scarfing by the conventional method. Assume theta is the inclined angle, W is the width of such banded part on the slab surface as is caused if theta is zero, and L is the length of a solvent flame.
