Title: Vehicle with lock up clutch
Inventor: NAKANISHI HITOSHI
IPC: F16H61/14
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To exert an engine brake and run safely by driving directly regardless of the number of engine rotation at the detection time of a costing running state. SOLUTION: When an operator removes his foot from an acceleration pedal 19 at the vehicular running time, an engine speed N becomes low regardless of a car speed. Therefore, as being in a basic control, if a lock up clutch 11 is ON, it is changed to OFF, while if it is OFF, it continues OFF. In other words, it is driven by a torque converter and an engine brake is not exerted. Therefore, when the controller 18 receives a foot remove signal S1 from a touch sensor 19a, if the lock up clutch 11 is OFF, it is changed to ON regardless of the basic number of rotation of a clutch intermittence and if the lock up clutch 11 is ON, the ON signal is inputted for a clutch change valve 11a in order to maintain ON. Therefore, the engine brake is exerted and a safe running can be ensured by a direct drive.

Title: Electron beam-excited phosphor
Inventor: MORIMOTO KIYOSHI
IPC: C09K11/62
Filed: 1986-06-26
Abstract: PURPOSE:To obtain an electron beam-excited phosphor which exhibits a high luminance even at a relatively low anode voltage, can enjoy high reliability for its long durability, and is suitable as a blue phosphor for use in fluorescent display tube, by doping a ZnO.Ga2O3 phosphor with Cd so as to lower the resistance. CONSTITUTION:1mol of Ga2O3, 0.5-4mol of ZnO and 5X10<-4>-3X10<-1>mol of CdCO3 are mixed with each other. The mixture is put in a heat-resistant container, e.g., an alumina boat and burned at about 1,300 deg.C in the air, thereby preparing a phosphor. The phosphor thus obtd. is pulverized and baked at about 1,000 deg.C in the air to obtain an intended electron beam-excited phosphor represented by the formula ZnO.Ga2O3:Cd. This phosphor has low resistance because of doping with Cd and, therefore, exhibits a luminance of 50ft-L even at an anode voltage of <=100V.

Title: Heat recovering system
Inventor: ITO KAZUHIKO
IPC: F23L15/04
Filed: 1987-06-16
Abstract: PURPOSE:To enable ensurance of a necessary amount of preheated air without increasing the size of a recuperator, by a method wherein a bypass line with a flow rate regulating valve is situated between a blower and a burner. CONSTITUTION:Bypass lines 11 and 11, not passing through recuperator 3, are formed between a blower 7 and a burner 9. Flow rate regulating valves 12 and 12 are mounted to the bypass lines 11 and 11 and are opened and closed by means of signals A and B from regulators 13 and 13 to control the temperature and pressure of preheated air fed to the burners 9 and 9. When the temperature of air in a preheated air feed line 10, measured by a preheated air temperature sensor 14, is increased to a value at which there is a fear of the burner 9 and the like being burnt to damage, the flow rate regulating valve 12 is opened, and the flow rate of the bypass line 11 is increased. Since a quantity of heat recovered by means of the recuperator 3 is all returned in a furnace 1, there is no need to increase the volume of the recuperator 3.

Title: Semiconductor laser optical system
Inventor: MIYAGAWA ICHIRO
IPC: H01S5/00
Filed: 1986-06-26
Abstract: PURPOSE:To reduce the effect of spontaneous radiation and extend a laser-beam dependent output region to a low luminescent region by providing an interference filter for selectively transmitting only light in a wavelength range including the laser beam wavelength. CONSTITUTION:A semiconductor laser 1 emits light with a quantity corresponding to an applied current and the light is incident on a collimator lens 2 provided in a light path. The light converted to parallel beams by the collimator lens 2 is incident on an interference filter 3. The interference filter 3 selectively transmits light in a wavelength range including the laser beam wavelength. Thus, the effect of spontaneous radiation is reduced and the large output region of the laser beam can be enlarged into a low luminescent region. Further, since the spontaneous radiation used by the interference filter is quasi-monochromatic, the effect of chromatic aberration can be removed. Accordingly, the laser beams can be focused to a small spot over a wide output range.
Patent JP-S6130090-A (JP)
Title: Semiconductor laser
Inventor: NISHI KENICHI
IPC: H01S5/00
Filed: 1984-07-20
Abstract: PURPOSE:To enable a coherant output having stable spatical mode to be readily obtained, by providing a stripe region so as to intersect a plurality of stripe- shaped oscillation regions, the region having a refractive index which is substantially equal to that of the oscillation regions. CONSTITUTION:On the same plane as a plurality of strip-shaped oscillation regions 11, a region having a refractive index which is substantially equal to that of the oscillation regions 11 is formed so as to intersect them. In an index waveguide area 13 in this structure, the light is propagated in a mode which is determined by the difference between the refractive index of the regions 11 and that of the regions around them. In the region 12, however, light is spread by diffraction since there is no difference between the refractive index of the regions 11 and that of the outside thereof. The provision of the region 12 enables optical coupling between the regions 11 to be effected at the region 12 highly efficiently. The light rays which are optically coupled at the region 12 are guided by the other portions of the regions 13 in the same manner as that in ordinary index waveguide type lasers. Accordingly, it is possible to obtain output light from the end face of the laser in a stable spatial mode. In addition, the laser does not involve unstableness due to the changes in the spatial mode.

Abstract: PROBLEM TO BE SOLVED: To obtain a soft or hard contact lens which has improved oxygen permeability, can be continuously fitted to an eye for a long time and can be easily handled from a hygienic viewpoint by forming lots of pores by irradiation of polyvalent heavy ion beams. SOLUTION: A lens having proper pore diameter and pore density as an oxygen permeating contact lens can be obtd. by irradiating a contact lens after formed with polyvalent heavy ion beams. More concreatly, a hard contact lens essentially comprising methylmethacrylate polymers or a soft contact lens essentially comprising a hydrophilic resin such as hydroxyalkyl methacrylate is irradiated with heavy ion beams to produce cores. It is preferable that after the irradiation of heavy ion beams, the lens is subjected to ultrasonic etching in the presence of chlorinated acetic acid. Thus, lots of pores having 50 to 1000Å average pore diameter and 10 to 10<9> /cm<2> pore density which penetrate the lens are produced while transparency of the lens is maintained.
