Title: Rivet fitting command preparing device for machine for fitting rivet to sheet-like material
Inventor: HIROSE MITSUHIRO
IPC: B21J15/14
Filed: 1982-04-30
Abstract: PURPOSE:To prevent collision of rivets with each other on a material, and to prevent damage of the material and a machine, by making a titled device to discriminate whether a fitting position data of a rivet is a data of contents coinciding with contents of a fitting position data of each existing rivet or not, when inputting said fitting position data to a storage device. CONSTITUTION:A rivet P is fitted successively and continuously onto a material 1 held by a holder 16, by moving it intermittently and relatively between the holder 16 and a rivet fitting unit 3, and a desired pattern is formed. When making a device store a new rivet fitting position, an indication is given by the second operating means 114L- 115B, 117 as to a rivet fitting co-ordinate position data. In accordance with this indication, a processing means 120 compares magnitude of an absolute value of a difference of co-ordinate position data between the new indication and the stored one, with magnitude of a data corresponding to size of the rivet. In accordance with a result of this comparison, whether the new rivet interferes with the rivet which is fitted by a rivet fitting command stored in a device 123 is discriminated successively. When it is discriminated that said new rivet does not interfere with the latter, the means 120 prepares a rivet fitting command in accordance with the co-ordinate fitting position data of the new rivet.

Title: Electrophotographic photoreceptor and its production
Inventor: ARAMAKI SHINJI
IPC: G03G5/06
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To effectively stabilize dispersion and to obtain an electrophotographic photoreceptor exhibiting excellent electrophotographic characteristics by using a block copolymer of monomer components, at least one of which forms a homopolymer soluble in or highly affinitive for alcohol as a polymer binder. SOLUTION: Relating to the electrophotographic photoreceptor with a layer contg. an electric charge generating agent comprising an org. pigment dispersed in a polymer binder, the polymer binder is a block copolymer of monomer components, at least one of which forms a homopolymer soluble in or highly affinitive for alcohol. Since the alcohol-soluble parts of the copolymer are directed outward and dispersion is stabilized, the alcohol-insoluble parts come in contact with the surface of the pigment and the deterioration of electrical characteristics is prevented.

Title: Semiconductor laser
Inventor: KURODA TAKAROU
IPC: H01S5/00
Filed: 1985-04-10
Abstract: PURPOSE:To obtain stable transverse fundamental mode oscillation by making the effective refractive index of beams in an active region smaller than that of beams in an optical waveguide region formed adjoined to said region. CONSTITUTION:An optical waveguide region at a central section A forms three- layer slab optical waveguides consisting of layers 5, 6, 7, and also confines beams in the vertical direction. Active regions B at both ends shape double hetero-type P-N junctions composed of layers 2, 3, 4, and the layer 3 represents an active layer in which the gains of a laser are generated. Consequently, the greater part of laser beams are confined in the layer 6 in the region A at a center, and beams of one part are projected to the layers 3 in the regions B, thus amplifying laser beams. When the refractive indices and thickness of each layer of the layers 2-7 are selected properly and the laser is designed so that the effective refractive index of beams propagated through the region A is made larger than those of beams propagated through the regions B on both sides at that time, stable transverse fundamental mode oscillation is obtained.

Abstract: PURPOSE:To make it possible to set at a proper level the room heating and room cooling capabilities with the air velocity kept at a value suitable for work by controlling the opening and closing of a damper for mixing cold air and hot air in such a fashion that the degree of the mixing is higher as the detected temperature is lower when cold air is used and the degree of the mixing is higher as the detected temperature is higher when hot air is used. CONSTITUTION:A control section 14 opens or closes a damper 13 according to a sensed temperature by a temperature sensor 12 to change the ratio of mixing of the cold air which has exchanged heat by a fan 5 for evaporation and the hot air which has exchanged heat by a fan 6 for condensation. For room cooling the room cooling capability of refrigerating cycle is set so as to bring proper environmental conditions at used maximum environmental temperature. When the temperature in the environment drops with the speed of the air blast from the air discharge port 7 kept constant, the temperature drop at the cold air discharge port 7 and in the temperature of the environment becomes large and over-room-cooling develops. The degree of temperature drop in the environment is detected by the temperature sensor 12, and the hot air which has exchanged heat by the fan 6 for condensation is introduced to the cold air discharge port 7 in an amount which is suitable for the temperature of the environment to bring about room cooling at a proper level. In room heating a hot air discharge port 8 or refrigerating cycle is reversed and hot air is taken out from the cold air discharge port.
