Title: Production of toner for developing electrostatic latent image
Inventor: SUGURO YOSHIHIRO
IPC: G03G9/097
Filed: 1990-09-25
Abstract: PURPOSE:To provide the toner which withstands practicable use as a dye penetrates (diffuses) sufficiently to the center of resin particles by using the dye, with which the relation between the solubility [D1] of the dye to an org. solvent and the solubility [D2] of the dye to the resin of the resin particle attains [D1]/[D2]<=0.5. CONSTITUTION:The resin particles are dispersed into the org. solvent which does not dissolve the resin particles and the dye is dissolved into the solvent before or after this dispersion to penetrate the dye into the resin particles and to color the particles; thereafter, the org. solvent is removed. The dye, with which the relation between the solubility [D1] of the dye to an org. solvent and the solubility [D2] of the dye to the resin of the resin particle attains [D1]/[D2]<=0.5, is selectively used as the dye in this case. The toner which penetrates (diffuses) the dye into the deep part of the resin particles is efficiently produced in this way.

Filed: 1990-09-26
Abstract: PURPOSE:To prevent the occurrence of a fixing defect of a transfer image by heating a belt by a heat source and allowing a recording medium to pass between the preheated belt and a heat roll to fix the transfer image on the recording medium. CONSTITUTION:A heat roll 30 is rotated to drive a belt 36, and a form 12 carried by a carrying device 21 enters between the belt 36 and the heat roll 30. At this time, the belt 36 is heated by power supply to a heating body 40 to approximate its temperature to the surface temperature of the heat roll 30, and heat and a pressure are applied in fixing nip parts 37 and 38 to fix the transfer image. That is, the temperature of the belt 36 is approximated to the temperature of the heat roll 30 to reduce the calorific value of the heat roll 30 covered with the belt 36 as much as possible. Thus, the power consumption of the heat source of the heat roll 30 is not increased to prevent the occurrence of a fixing defect of the transfer image.

Title: Friction welding equipment
Inventor: HASEGAWA TSUTOMU
IPC: B23K20/12
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To contrive miniaturization of a friction welding equipment and improvement of controllability while a motor for driving the main shaft is arranged coaxially with it. SOLUTION: The rear end 1a of the main shaft 1 is directly connected to the revolving shaft Ms of a motor with a coupling 4. Accordingly, the members relating to the rotary driving of the main shaft 1 are all arranged coaxially with the main shaft 1 and directly connected. As a result, mechanical elements for transmission such as a pulley and a belt are unnecessary, enabling moment of inertia to be reduced for the entire rotary driving means. Consequently, controllability can be enhanced concerning braking. In addition, lengthening of the device as well as generation of twisting due to the extension of the main shaft, for example, can be prevented by arranging an actuator 10, a motive power source of a chuck 2, not coaxially with the main shaft 1 but on the circumference.

IPC: F02D43/00
Filed: 1992-09-25
Abstract: PURPOSE:To reduce production of the fluctuation in output torque of an engine by compensating for a fluctuation in an amount of air passing through an air mixture passage by means of an amount of air passing through a bypass passage, resulting in suppression of a fluctuation in an amount of air fed to a combustion chamber, by providing amount of air passing through the bypass passage and the air mixture passage with correlation therebetween when the two passages are simultaneously provided.

Title: Manufacture of semiconductor device
Inventor: MIURA SHUICHI
IPC: H01L21/205
Filed: 1984-12-05
Abstract: PURPOSE:To decrease the number of pin-holes and to restrain the formation of the etch-pit by successively building up the silicon dioxide film and the aluminum nitride film as the inhibiting film of crystallization in the region in which crystal growth is not performed and by the selective growth of the semiconductor crystal on the semiconductor substrate or the semiconductor layer. CONSTITUTION:The SiO2 film 7 and AIN film 2 as the inhibiting film of crystallization are successively adhered in the region where the crystalline growth is not performed on the GaAs substrate 1. By the growth of the GaAs crystal, the polycrystalline layer 3 grows on the AIN film 2 and the single crystal layer 4 grows on the substrate 1. When the polycrystalline layer 3 is removed by the etching, it is very rare that the pin-hole 5 on the AIN film 2 and the pin-hole 8 on the SiO2 film 7 overlap with each other and penetrate the two layers, so that the probability of formation of etch-pits is decreased. When the AIN film 2 and the SiO2 film 7 are removed, the etch-pit on the substrate 1 can hardly be observed. As AIN is applied to the upper most layer, the abnormal growth between the single crystal layer and the polycrystalline layer does not exist and the denaturation caused by the thermal strain of the substrate is restrained.

Title: Multifiber optical connector and its manufacture
Inventor: TAKIZAWA KAZUHIRO
IPC: G02B6/40
Filed: 1995-09-09
Abstract: PROBLEM TO BE SOLVED: To shorten the measurement time when connection characteristics of many multifiber optical connectors are inspected with a master connector by making the internal diameter of the rear end part of the guide hole of a guide pin less than that of any other part. SOLUTION: The rear end part 120 of the guide hole 12 of a ferrule 10 is made a little smaller in internal diameter (thickness) than any other parts 122 so that the guide pin can be pressed in from before by applying a very small force. The ferrule 10 which has the guide hole 12 is manufactured by arranging a molding pin of the guide hole 12 in a metal mold and charging resin. At this time, the shape of the molding pin is altered and then the ferrule 10 having a guide hole 12 with a rear end part 120 which is a little thinner can be formed. When the connection characteristics of many multifiber optical connectors are inspected with the master connector, the guide pin is left on the master side at the time of the attachment and detachment of the ferrule 10, and the need to insert the guide pin each time measurement is performed is eliminated.

SOLUTION: Partitions 14, 24 are disposed inside of side surfaces 10, 20 of housings 1, 2 over the entire circumference with relief portions 13, 23 formed between the side surfaces 10, 20 and the same. Gel sheets 6, 7 provided with rectangular openings 61, 71 greater than a connector 3 and having an outer diameter smaller than the inner circumferential surfaces of the side surfaces 10, 20 are mounted on the partitions 14, 24, respectively. A wire 4 is introduced outside from between grooves 12, 22 and other grooves 11, 21. Another wire 5 is introduced outside from between grooves 17, 27 and other grooves 16, 26. The sheets 6, 7 are held under pressure between the partitions 14, 24 by the housings 1, 2, and are deformed in conformity with the shape of a pressing surface to be intruded into clearances thereof.  The excessive portions of the sheets 6, 7 are intruded into a space defined by the partitions 14, 24 and the relief portions 13, 23. Consequently, it is possible to reduce reaction at the time of pressing and enhance efficiency of assembling operation, thus preventing any deformation of the housings 1, 2 at the time of pressing or any leakage of the sheets 6, 7.

Filed: 1995-10-04
Abstract: PROBLEM TO BE SOLVED: To provide an efficient continuous precipitation machine by providing a flow homogenizing zone ensuring the disappearance of inlet energy and the uniform speed profile at an outlet and a precipitation work zone of homogenous flow keeping a high field number and a uniform speed profile. SOLUTION: A zone 2 forms a flow homogenizing zone and the length thereof is determined so that inflow energy is naturally dissipated and a uniform speed profile is obtained at the outlet of the zone 2. A zone 3 is a precipitation work zone and the size thereof is large as compared with the general size of a continuous vertical precipitation machine, and homogenous flow free from turblent flow is shown over the length of the zone 3 and this quiet flow can keep a regular speed profile. A zone 4 forms an outlet zone of a sedimented substance and a treated liquid, and the distortion of speed related to the previous zone is avoided. Therefore, the separation of flow and recovery are performed and the treated liquid is recovered at a surface part and the sedimented substance is recovered through the bottom of the continuous vertical precipitation machine.
