Title: Dc/dc converter
Inventor: ISHIGURO HIDEO
IPC: H02M3/335
Filed: 1981-11-02
Abstract: PURPOSE:To reduce the noise of a DC/DC converter by discharging the energizing energy of a transformer in a reverse flow passage of a diode provided in parallel with a main switch, regenerating it to a power source, thereby minimizing the variation in the voltage during OFF period and eliminating the reset of the energy.

Thus, the electric power is transmitted to the output side when the transistor 4 is switched ON. When the transistor 4 is switched OFF, a free resonance state is formed with the capacity between the inductance of the transformer 3 set to large value and capacity between the wires and the floating capacity of the transistor 4, and the energy is regenerated through the diode 2 to the power source 1.

Title: Production of magnetic recording medium
Inventor: YAMAGISHI KOICHI
IPC: G11B5/84
Filed: 1993-06-23
Abstract: PURPOSE:To prevent scratches on a magnetic recording medium or a magnetic head even when the floating height of a magnetic head is set low by forming a lubricating layer within a specified period after a protective layer surface subjected to polishing and cleaning treatment is washed with water and dried. CONSTITUTION:The medium may be subjected to only washing with water in a pure water at temperature from room temp. to 70 deg.C for one min. to about two hours, but it is more effective to use ultrasonic waves. The quality of water to be used is not limited but it is preferable that water has high resistivity and contains little org. material, fine particles and dissolved oxygen. The protective layer after washed with water is dried, preferably by spin drying. Within 30 min. after drying, a lubricating layer comprising such as perfluoroalkyl polyether is formed to obtain a magnetic recording medium. In this process, if the lubricating layer is formed after 30min. or a longer time passed after drying, deposition of impurities in an atmosphere which occurred before washing again occurs. Thereby, formation of the lubricating layer should be done within 30min.

Filed: 1985-08-08
Abstract: PURPOSE:To make the wiper structure simple and reduce the trouble rate, by installing a wiper arm slidable laterally around a single fulcrum, and installing a wiper blade to the wiper arm to slide together with the arm. CONSTITUTION:A single wiper arm 7 is made slidable laterally around a single fulcrum O. To the wiper arm 7 is installed a wiper blade 8 slidable together with the wiper arm 7. In such a structure, when the arm 7 slides to the left, the distance d1 between the blade 8 and the fulcrum O is shortest, and when the arm 7 slides to the right end, the distance d2 between the blade 8 and the fulcrum O is the largest. Therefore, the wiping area by the single wiper is oblong as if two wipers act to wipe, to cover an oblong field of vision sufficiently.

Title: Method of bonding
Inventor: ABUMIMOTO TOSHIMI
IPC: C09J5/00
Filed: 1985-08-10
Abstract: PURPOSE:To prevent nonuniform bonding and slippage through reduction of the thickness of a bonding layer to substantially zero, by forming a thin film at one end of the bonding surface of at least one out of two solid members, placing the bonding surfaces of both members opposite each other to form a wedgy space between the bonding surfaces and pouring an adhesive into the space. CONSTITUTION:Two solid members 1, 2 are bonded with an adhesive using a step of forming a thin film 3 at one end of the bonding surface of at least one solid member (e.g., 2) selected from the both solid members, a step of placing the two solid members 1, 2 opposite each other in such a manner that the bonding surface on which the thin film 3 is formed is arranged on the inside to form a wedgy space 8 between the bonding surfaces, and a step of pouring an adhesive into the space 8. For example, a groove 4 which serves as an adhesive pouring port may be formed around the thin film 3 of the bonding surface of the solid member 2. According to the title bonding method, mass bonding can be conducted at once with a predetermined jig. Further, what is needed after bonding is only to cut off the unnecessary portion such as the groove 4. Therefore, there is no need to reprocess the bonded members due to the slippage caused during the bonding.

Title: Image forming device
Inventor: TAMURA SATOSHI
IPC: G03G15/16
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To prevent staining of a transfer sheet caused by the fact that an image density control patch formed in a nonimage forming region on a photoreceptive drum is electrostatically stuck to a transfer sheet carrying a recording material. SOLUTION: Paper passage and nonpassage positions of a transfer sheet corresponding to the image and nonimage forming regions of a photoreceptive drum have surface potentials of 4 kV and 1 kV respectively. Thus, the potential difference between the image density control patch (-2 kV) formed in the nonimage forming region of the photoreceptive drum and the surface potential of the part corresponding to a nontransferred toner image (the position facing the image density control patch) of the surface of the transfer sheet coming into contact with the photoreceptive drum in a transferring part is made small to hardly or never electrostatically transfer the nontransferred toner image to the transfer sheet, so that its staining with the nontransferred toner image can be prevented.

Abstract: PURPOSE:To make use of a titled case irrespective of pressence or absence of a disc unloading mechanism of a reproducing device by unloading a disc in the case from the opened half-above of the case and constituting it so that a disc mounting member can be taken out from the opening part of the case. CONSTITUTION:A disc accommodating case is inserted into a reproducing device provided with a disc unloading mechanism and pressed to the innermost part of the device, and a locking part of the device locks a closed part 22 of a disc mounting member 3. Under this condition, when the main case is taken out the disc mounting member 3 is set on the device. After the completion of reproducing, the device is set as an unloading mode, and the empty main case is inserted into the innermost part of the device again and the disc mounting member 3 can be unloaded with the case. At the absence of the unloading mechanism, the disc is taken out on the condition that a cover part 1 is opened from a base part 2 and mounted in the regenerating device. After the completion of reproducing, the disc is taken out from the device and accommodated into a recessed part 20 for accommodating the disc of the case mounting member 3. Thus, the case which can be used irrespective of the presence or absence of the disc mounting mechanism is obtained.
