Filed: 1984-01-30
Abstract: PURPOSE:To prevent the input-output leakage as well as a ghost phenomenon by providing a gap part to a printed wiring board set between input and output terminals of a filter element and at the same time masking a space part between the input and output. CONSTITUTION:A gap part 154 is provided to a printed wiring board 150 set between input and output terminals 151 and 152 of a filter element 74. Then a shielding plate 155 is set orthogonally to a frame to mask a space part formed between the input and output of the element 74. The plate 155 consists of a shielding plate 155' at the case side and a shielding plate 155'' at the terminal side. The plate 155' has a cut formed at the middle part and fitted to the case of the element 74 with such a size that secures contacts at both sides of the plate 155'. While the plate 155'' has a size that secures contacts with the side faces of the frame and a partitioning plate. Then the case part of the element 74 is put into the cut part of the plate 155' with the plate 155'' set between terminals 151 and 152. Thus the element 74 is held between plates 155' and 155''.

Title: Tracking method of optical disk driving device
Inventor: FUJITA KINICHI
IPC: G11B7/085
Filed: 1994-01-13
Abstract: PURPOSE:To avoid the influence of scratches and stains on the surface of an optical disk by calculating the moving time of a pickup part on the basis of a distance from a track where the current pickup part is located to a target track. CONSTITUTION:A moving distance calculating means 2 for an optical pickup part calculates a number of jumped tracks from a difference between positions of a target track and a current track, calculates a moving distance by multiplying the number of tracks by a track pitch and sends a moving distance 2a to a moving time calculating means 3 for the optical pickup part. The calculating means 3 divides the moving distance by the moving speed of an optical pickup part 7, calculates a moving time 3a and sends the moving time to a thread motor controller 5 after setting a timer. Consequently, since the moving position of the optical pickup part 7 is thus controlled, the influence due to scratches and stains on the surface of the optical disk is removed.

Title: Production of two-split rim
Inventor: TORIYAMA TAROU
IPC: B60B21/00
Filed: 1979-02-15
Abstract: PURPOSE: To produce the rim of thin plate thickness, lightweightness and even strength by producing a blank from an aluminum plate, softening its periphery and working the same to the rim.  
     CONSTITUTION: A rigid or semi-rigid aluminum plate is used. Material quality of 5052, 5454 or the like is used. A blank is produced from the aluminum plate by a blanking press or a circular shear. Next, only the peripheral part 7 of the blank 5 is softened by an annealing method such as low-frequency heating or flame.  The softening is selected to annealing or semi-rigid depending upon the material quality of the blank, plate thickness and the degree of working for molding to the rim. This blank is spinned or pressed to a rim 1. The working causes work-hardening and an increase in strength. The work-hardening is higher as it goes toward the periphery from the blank center. In the above manner, the rim of uniform and high strength is produced.

Abstract: PURPOSE: To improve a servicing quality, a performance at low cost and a steering performance by connecting an aerodynamic steering blade and a thrust deviating body to each other in a manner to make connection and disconnection thereof easy and making at least the aerodynamic steering blade independently controllable after disconnection thereof. CONSTITUTION: Movement of a linear actuator 1 causes an aerodynamic steering blade 3 to be swung through an arm 2.

Title: Operation stoppage device for dehumidifier when water level reaches full level
Inventor: TOYOMOTO KOUJI
IPC: F24F13/22
Filed: 1982-02-02
Abstract: PURPOSE:To simplify the structure of the dehumidifier and to operate it accurately by a method wherein a switch is turned ON and OFF by the vertical movements of a float within a tank for storing water resulting from dehumidification, through a lever. CONSTITUTION:When the level of the water in the tank 7 exceeds a point C, the rear end of the lever 17 leaves away from a microswitch as the float 16 rises to the surface of the water. Accordingly, the microswitch 13 turns OFF to thereby stop the dehumidifier. On the other hand, when the water in the tank 7 is discharged, the float 16 lowers and the lever 17 turns the microswitch 13 ON to re-operate the dehumidifier. In this case, when the tank 7 is removed from the dehumidifier, the rear end of the lever 17 moves to a position separated from the microswitch 13 so that the microswitch does not operate. As a consequence, the dehumidifier is operated accurately and the structure thereof is simplified to thereby facilitate the assembly.
