Inventor: NAGAMURA YOSHIAKI
IPC: H05K5/03
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To easily look at a display by varying the height of a tilting leg in rear of a housing so as to adjust the angle of a flat panel display so as to deviate the centroid of a product. SOLUTION: In the state of standing a tilting leg 16 in rear of a housing, a projection 30 is brought into contact with a main body 10 to work for keeping the angle of the leg 16. In the case of rotating the leg 16 with a spindle 31 as a center to lower tallness next, it is moved to a prescribed position via a prescribed angle. Then, the main body 10 is deformed by pushing up it by the projection 30 and then the deformation is returned to obtain an appropriate clicking feeling without stopping at a neutral position. Thus, a displaying part is easily looked by deviating the centroid of the product of a flat panel display.

Title: Range hood
Inventor: YOSHIDA YOSHINORI
IPC: F24F7/007
Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To enable a range hood to be used safely even for a roaster by a method wherein the hood is provided with a timer switch for operating a blower device for a specified period of time and an operation of the blower device is carried out for a specified period of time regardless of a presence or a non- presence of a sensing signal of a flame sensor when the timer switch is turned ON. SOLUTION: When a timer switch 12 (for a roaster) is turned ON, an operation of a motor is started at a rotating speed of 'intermediate' irrespective of an operation of an operation switch 11a. Then, as the operation switch 11a is changed over during the operation, the operation of the fan is continued up to a timer elapsing time at a rotating speed of each of the changed-over 'weak', 'intermediate' and 'strong'. In addition, as 'OFF' of the operation switch 11a is pushed ruing the operation, the operation is stopped. In this way, when the timer switch 12 is turned ON, the blower device is rotated only for a set predetermined time suitable for completing a fish broiling in a preferential manner irrespective of a presence or absence of a sensing signal of a flame sensor 10.

Filed: 1991-10-11
Abstract: PURPOSE:To reduce the size of a gear device by providing plural thrust collars on both side surfaces of one side helical gear, and making one of plural clearances for discharging lubricating oil supplied to a gear and the thrust collars smaller than the other thereof. CONSTITUTION:In a high peripheral speed helical gear, lubricating oil supplied to the mesh portion is pushed aside along the tooth trace following the rotation, and discharged to the side of the mesh end. Clearances are provided between the helical gear 8 and thrust collars 9. One clearance L2 on the mesh end side is adapted to discharge the lubricating oil obtained by adding the lubricating oil supplied to the thrust collar 9 contact surface to the lubricating oil pushed aside along the tooth trace. The other clearance L1 on the mesh start side is good for discharging only the lubricating oil supplied to the thrust collars 9 and can be made smaller than the mesh end side clearance L2. Thus, the distances between the collars 9 and between bearings can be decreased so as to reduce the size of the whole device.

Title: Method for forming image, image-forming substance and colorless liquid used in the method, and method for deleting image
Inventor: KANEKO TETSUYA
IPC: C09D11/00
Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To form durable images easy to remove to fit a reproduction method by applying only to an image form part a colorless liquid including a component obstructing fixation of an image-forming substance before applying or transferring the image-forming substance to a material to be recorded and forming images of a low fixability. SOLUTION: When a coat-like image is to be formed on a material to be recorded with the use of an image-forming substance containing a coloring material and a resin, a colorless liquid containing a component obstructing fixation of the image- forming substance is applied only to a part where the image is to be formed before the image-forming substance is transferred or applied to the material to be recorded, whereby the image of a low fixability is formed. In the meantime, an image of a high fixability can be obtained by forming the image without applying the colorless liquid. The low-fixability image can be easily removed by applying a mechanical shearing force or pressuring. An anionic surface active material, a resin or the like is used as a substance for lowering the fixability of the image-forming substance to the material to be recorded.
