Title: Air cleaning device
Inventor: MIYAUCHI NORIO
IPC: F04D27/00
Filed: 1994-04-12
Abstract: PURPOSE:To enhance the efficiency of a blower and to reduce power so as to save energy. CONSTITUTION:An outlet width adjusting member 20 surrounds the outer periphery of the upper part on the inlet side of the blow-off port 11b of a blower impeller 11, and accordingly, the upper end part of the blow-off port 11b is isolated by the width adjusting member 20. Accordingly, the air capacity at one and the same speed decreases but the air speed can be made to be substantially constant in the lower part thereof. Accordingly, a slow speed part of the stream of air blown out from the blow-off port 11b is blocked by the outlet width adjusting member 20 and the air speed in the opened part of the blow-off port 11b is set to be constant, thereby it is possible to surely enhance the efficiency of the blower.

IPC: B05D7/14
Filed: 1990-03-26
Abstract: PURPOSE:To improve the productivity without requiring time for baking of a metallic resin film by baking a synthetic resin film by the heat generated in a metallic material at the time of working of the metallic material. CONSTITUTION:The metallic material 1' prior to working molded by a metallic mold 2 evolves heat and increases the object temp. when the material is plastically deformed. The metallic material 1' is, thereupon, passed through a synthetic resin tank 3 where the synthetic resin is baked by the above-mentioned temp. increase. The heat can be raised by increasing, for example, a working speed or increasing the degree of the plastic deformation. The metallic material 1' is passed in the synthetic resin tank 3 and is then put into a water cooler 4 by which the material is cooled in order to prevent the thermal deterioration of the resin. Namely, the incorporation of the baking stage for the synthetic resin film into a series of the flow of the working stages is possible and, therefore, the productivity is improved.

Title: Motor speed controller
Inventor: SHIRONOKUCHI HIDEKI
IPC: H02P29/00
Filed: 1990-03-23
Abstract: PURPOSE:To sustain a target speed highly accurately and to simplify the circuitry by providing a frequency comparator producing a digital signal corresponding to the frequency difference between a speed signal and a reference frequency signal and a phase comparator producing an electrical signal corresponding to the phase difference between the speed signal and the reference frequency signal. CONSTITUTION:A motor 1 has a first analog voltage V1 maintained at a constant high level in a low speed region immediately after start and arrives in a lock range at a high rising rate. Consequently, the first analog voltage V1 controls the motor speed, around point P1 according to the frequency difference, in the direction matching to the frequency of a reference clock signal S2. Upon frequency matching, a second analog voltage V2 varies around point P2 in the direction for eliminating the phase difference between a speed pulse S1 and the reference clock signal S2 thus sustaining a target speed of the motor, determined by the reference clock signal S2, with high accuracy.

Title: Locking device for correction means
Inventor: WASHISU KOICHI
IPC: G03B17/00
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To facilitate the attachment of a locking member and a supporting member and to improve reliability by providing a rotation regulating member allowing the rotation of the locking member in a 1st direction and regulating the rotational amount in a 2nd direction opposite to the 1st direction. SOLUTION: When a lock ring 76 fit in a bottom board 71 is rotated in a clockwise direction, a hook 71k runs onto a hook relief part. When the rotation of the ring 76 is kept further, the tip of the hook 71k is caught by the step part 76h of the ring 76, so that the rotation of the ring 76 is prevented by the hook 76k and the step part 76h even if the ring 76 is tried to be rotated clockwise. Therefore, the ring 76 is rotated counterclockwise to an angle at which a lock ring regulation part 76g abuts on a bottom board projection 71i from the above state, and locks/unlocks a supporting frame 77 between the angles. In such a case, the hook 71k functions as the rotation restricting member allowing the rotation of the ring 76 in the counterclockwise direction (1st direction) and restricting the rotation in the clockwise direction (2nd direction).
