Inventor: TAKANO MASAHIDE
IPC: G03G5/08
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a positive electrification electrophotographic photoreceptor in which negative charges produced by negative corona discharge in the transfer process are decreased to suppress difference in the image density, and to provide an easy and stable production method which includes a method to avoid environmental pollution. SOLUTION: A conductive base body 1 of aluminum or its alloy is immerged in warm pure water, drawn up and dried to form an oxidized film 2 of 15nm to 100nm thickness on the surface. Then a p-type base coating layer 3 of 0.3 to 0.8μm thickness is formed on the film 2, and further a photosensitive layer 4 of pure selenium or selenium alloy and a protective layer 5 are successively formed thereon by vapor deposition. Thus, the obtd. positive electrification photoreceptor shows decrease in the negative charges due to negative corona discharge while the photoreceptor maintains good ranges of functional characteristics such as a potential holding rate, sensitivity, fatigue due to the repeated use and of image quality.

Title: Light source device
Inventor: KUBOTA YOJI
IPC: G02B27/09
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To provide a light source device that improvement in utilization of light, uniformalizing of intensity distribution of emitted light, and reduction in a diameter of the emitted light beam can be achieved at the same time. SOLUTION: In this light source device, the whole light I1 emitted from a reflector 3 is separated into four division light fluxes 12 by a condenser lens array 10. When these light fluxes I2 pass through a prism 11, they are converted into a luminous flux I3 of the circular cross section where the light intensity distribution is uniform. The diameter of this luminous flux 13 becomes smaller than that of the light I1 emitted from the reflector 3. Therefore, according to this light source device, it is possible to achieve improvement in light utilization efficiency, uniformalizing of intensity distribution of the emitted light, and reduction in the diameter of the emitted light at the same time.

Title: Forming method for magnetic tape cassette
Inventor: KATAGIRI SHINGO
IPC: B29C45/14
Filed: 1988-10-13
Abstract: PURPOSE:To simplify the production process of cassette halves where a transfer forming process using a transfer film is applied by specifying the tip form of a nest pin of a metallic mold which forms the hole part of each cassette half. CONSTITUTION:A transfer film 20 is set as if it were held by a metallic mold and then held between the tip parts of the nest pins 30 and 31. In this case, the film 20 is intensively bent at an acute angle by a crown-shaped projection part formed at the periphery of a tip fringe 39 of the pin 30. As a result, a transfer layer 12 of the film 20 is fragily broken at the periphery of the fringe 39. This broken layer 12 is stuck to a base film 6 and removed as it is when the film 6 is removed from the surface of a cassette half. Thus it is not required to remove the foil flashes after a transfer forming process.

Title: Cooperative control device for vehicle
Inventor: NIIMURA TOMOYUKI
IPC: B60W10/12
Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To prevent auxiliary steering torque giving unfamiliar feeling to a driver from being generated by an erroneous correction current and a noise signal, in a cooperative control device for a vehicle for cooperatively controlling a driving force distributor and an electric power steering gear to reduce a torque steer phenomenon. SOLUTION: Since a driving force distributor is actuated at the time of turning acceleration of a vehicle, a correction current for correcting a motor control signal of an electric power steering gear is brought into zero fundamentally in an operation condition other than the turning acceleration. A switching means M14 is turned off to block the correction current (or a noise signal) not to give unfamiliar feeling to a driver by generation of improper auxiliary steering torque in the power steering gear, when the correction current not output fundamentally is output accidentally because of a trouble at the time of unoperated condition of the driving force distributor, and when the noise signal not discriminated from the correction current is output even at the time of no correction current.
