Title: Image forming device
Inventor: YOSHIDA YASUYOSHI
IPC: G03G21/00
Filed: 1989-12-18
Abstract: PURPOSE:To prevent the ozonolysis ability from being deteriorated because a device is used for a long time by providing a heat source to at least one of the rotating bodies of a fixing means, simultaneously forming an aperture part to both end faces of the rotating body and using it as an exhaust path which is communicated to an exhaust means. CONSTITUTION:The fixing means 15 has a pair of rotating bodies 22 which press-contact each other and at least one of the bodies 22 has the heat source 23. Simultaneously, the aperture parts 22b and 22c are formed to both end faces thereof and used as the exhaust path communicated to the exhaust means 28. Therefore, when air in the device including the ozon is passed inside the rotating body 22a having the heat source 23 and exhausted, the ozon can be thermally decomposed. Thus, even when the device is used for a long time, the elimination performance of the ozon is not deteriorated. Besides, the eliminating effect of the ozon is improved more by jointly using an ozon filter 29.

Title: Image forming apparatus
Inventor: FUJITA TORU
IPC: H04N1/23
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To eliminate a streaky fluctuation extending in the main scanning direction by forming dots at an interval specified times as long as the diameter of an exposing spot in subscanning direction and growing the dot only in the main scanning direction until it is coupled with the dot in an adjacent cell in the main scanning direction. SOLUTION: A laser driver 204 delivers a signal for turning a laser beam on/off to a laser scanner 103 based on a quantized data received from an intermediate processing section 203. When dots are arranged at an interval 1.5 times as long as the spot diameter, the quantity of light of an adjacent dot is not effected substantially even if the position of adjacent dot is fluctuated by one pixel due to fluctuation of feeding. Furthermore, interference of dot can be prevented in the low density region essential for image quality and fluctuation of density can be suppressed because growth of dot is suppressed in the subscanning direction until it is coupled with an adjacent dot in the main scanning direction.

Title: Speaker and mounting structure of speaker
Inventor: MATSUMOTO FUTOSHI
IPC: H04R1/02
Filed: 1994-12-28
Abstract: PURPOSE: To reduce the member cost, assembling cost and mounting cost by reducing component members and to make a speaker light in weight by preventing the leakage or the sound outputted from the speaker in a lateral direction by the projecting part of an edge and an elastic body. CONSTITUTION: An edge 12 is formed into an annulus ring shape by the supporting member of a diaphragm 11, and a seal part 13 preventing the lateral leakage of the sound outputted from a speaker 10 is integrally formed with the edge 12 on the outer periphery part. In the seal part 13, grooves 14 are formed all over the peripheries to weaken the elastic intensity and make it easy to fit to an opposite member, and the shapes of the grooves 14 and the number of the grooves 14 are determined by the shape and material, etc., of the seal part 13. Because the elastic projecting part which is integrally formed with the edge 12 and the elastic body provided on this projecting part form a wall all over the outer peripheries of the front opening part of the speaker, the leakage of the sound outputted from the speaker 10 in the lateral direction is prevented.  Because the edge 12 and the elastic projecting part are integrally formed, the number of component parts is reduced and cost is reduced.

Title: Supercharging pressure controller for engine
Inventor: KASHIMA TAKAMITSU
IPC: F02B37/12
Filed: 1990-11-27
Abstract: PURPOSE:To make the maximal supercharging pressure widely variable by providing a first actuator operating in the direction of closing a bypass passage of a turbine concurrently with a second actuator operating in the direction of opening this bypass passage. CONSTITUTION:When a supercharging pressure is increased through operation of a turbo-charger 14 to reach a maximal supercharging pressure, a waste gate valve 15 is clockwise rocked through operation of a second actuator 18 and thus is gradually opened. Consequently, the supercharging pressure through operation of the turbo-charger 14 is prevented from exceeding the maximal supercharging pressure level, whereby it is kept at this maximal level. On the other hand, when the alcohol concentration M in the fuel is approximately 0% and the maximal supercharging pressure is controlled nearly to 0kg/cm<2>.G, a force which acts on the waste gate valve 15 through operation of a first actuator 17 is lost. In this way, the maximal supercharging pressure can be made widely variable from a level approximate to 0kg/cm<2>.G or so in corresponding relation to the operation conditions of the engine.
