Title: Photocatalyst and air conditioner using this catalyst
Inventor: ARIGA TORU
IPC: B01D53/86
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To obtain a water-resistant photocatalyst which is highly active photocatalytically and tightly adheres to the base of a catalytic coat by using organoalkoxysilane as a binder, in a photocatalyst bearing the catalytic coat on a base through sticking a photocatalytic particle to the surface of the base together with the binder. SOLUTION: The photocatalyst which decomposes an organic matter or an odor by emitting a light is formed by sticking a photocatalytic particle 5 to the surface of a base 1 together with a binder 6 and thereby causing a catalytic coat to be borne on the surface of the base 1. In this case, organoalkoxysilane is used as the binder 6. In addition, the ratio of the binder 6 in the catalytic coat is set within the range of 20-90wt.% and thus it is possible to obtain an adequate photocatalytic activity in the catalytic coat and also its adhesion to the base. Further, an absorbent can be contained into the catalytic coat borne on the surface of the base 1 and in this case, the ratio of the binder 6 in the catalytic coat is 20-80wt.%. Besides, in order to improve the adhesion of the catalytic coat, silica can be added to the binder 6.

Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of accurately measuring the stuck toner amount, as for a toner pattern with the stuck toner amount equivalent to the highest density, and capable of serving for the density control of a reproduced image. SOLUTION: The device is provided with a 1st toner pattern sensor 10 for measuring the amount of toner sticking to the toner image on a carrying belt 27 and a 2nd toner pattern sensor 11 for measuring the amount of toner sticking to the toner image on the photoreceptor drum, near a photoreceptor drum.

Title: Optical disk
Inventor: KOISHI KENJI
IPC: G11B7/24097
Filed: 1981-04-16
Abstract: PURPOSE:To detect a starting end position precisely during high-speed retrieval by employing uneven phase groove structure for a rotation starting end detection mark for detecting one turn of an optical disk, and an address starting end detection mark for detecting the position of the address area of each track. CONSTITUTION:At the circumference part of an optical disk provided with two address areas 1 on concentric circular groove-shaped guide tracks, an address starting end detection mark (address mark) 3 is formed in an arc having an angle equal to that of the address areas 1 as the same groove structure body with the track guide groove similarly to a sector starting end detection mark 4 and a rotation starting end detection mark 5 for detecting one turn of the disk. Consequently, a detection system for an index mark area 7 only detects the overall reflectivity of an index mark 10, so an inexpensive incoherent photodetection system is usable. Therefore, a starting end position is detected stably and precisely even during high-speed retrieval.

Filed: 1988-03-11
Abstract: PURPOSE:To reduce a flow passage loss as well as to enhance an adiabatic effect of intake gas by interconnecting a suction tube and an inlet muffler to each other with a joint spring engaged parallelly in the axial direction of a hermetically sealed vessel. CONSTITUTION:An interval between a suction tube 4 tightly attached to an upper shell 1a of a hermetically sealed vessel 1 and an inlet muffler 3 is interconnected by a joint spring 6 engaged parallelly in the axial direction of the vessel 1.

Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of an oil clearance by forming the oil clearance between the bearing face of the inner periphery of a pair of half-split sliding bearings and a rotational shaft, and rotatably supporting the rotational shaft. SOLUTION: In this assembling structure for half-split sliding bearings 2, the oil clearance formed between bearing faces 2a and the outer periphery of a rotational shaft can be secured with high accuracy. The thickness (t) of the half-split sliding bearings 2 is made the largest at the center section in the peripheral direction and is made gradually thinner to both sides in the peripheral direction. The minimization preventing structure of an eccentric oil clearance is employed for a bearing face 2a, and the oil clearance can be optimized during the motion of the rotational shaft.  The thickness (t) of the half-split sliding bearings 2 for securing the optimum oil clearance can be easily sized due to this characteristic as compared with a cylindrical sliding bearing, and the half-split sliding bearings 2 are advantageous for the machining work due to eccentric machining applied to a semicylindrical face.
