Title: Optical disk device
Inventor: OZAKI MINORU
IPC: G11B7/00
Filed: 1985-04-26
Abstract: PURPOSE:To omit an exchange track by using an exchange sector separated by the prescribed number of tracks if exchange sectors are insufficient. CONSTITUTION:In an optical disk device, data are recorded in the optional sector area 2 of a user area on a rotating optical disk 1, whether the data are correctly written or not is confirmed after waiting by one rotation, and if error status is bad, the data are rerecorded in an exchange sector area 3 on the same track to avert a defect on the optical disk 1. When data are already recorded in an exchange sector area 3, a recording head is successively moved in a track direction by the already determined number of tracks during one rotation. The data shunted in the exchange sector area 3 on the track after movement are rerecorded.

IPC: G11B5/187
Filed: 1985-04-26
Abstract: PURPOSE:To prevent a magnetic head from the increase of a spacing loss by forming a leading end part having a sliding surface on which a magnetic gap is formed so that its thickness in the length direction of the magnetic gap is gradually reduced in the depth direction of the magnetic gap. CONSTITUTION:The magnetic gap 5 is formed on the sliding surface 2a which slides 1 magnetic tape and the leading end part 2A of the magnetic head 2 having the sliding surface 2a is formed so that the thickness W in the length direction of the magnetic gap 5 is gradually reduced in the depth direction of the magnetic gap.

Abstract: PURPOSE:To detect the quantity of harmful ultraviolet rays contained in the sunlight according to the skin of a user by providing ultraviolet-ray transmission filters for long waves and short waves. CONSTITUTION:A threshold value corresponding to the skin of the user is set 15 first. In this state, when a solar battery 1 receives the sunlight in this state, an ultraviolet-ray A wave (long wave) in the sunlight is transmitted through an A-wave transmission filter 7 to reach one aluminum electrode 5 through a transparent electrode 3 and an a-Si pin layer 4, and an electromotive force corresponding to the A wave is generated 5. Further, a B wave which is trans mitted through the B-wave (short wave) transmission filter 8 reaches the other aluminum electrode 6 through a transparent electrode 3 and the layer 4 and an electromotive force corresponding to the B wave is generated 6. Then the electromotive force is signal-processed 10 and outputted to a microprocessor 13. The processor 13 performs arithmetic operation according to the input signal and calculates the quantities of ultraviolet-ray energy corresponding to the A wave and B wave and compares it with the threshold value. When one calcu lated value reaches the threshold value, the processor 13 outputs a warning signal to a display part 16 and an alarm 17.

Title: Ink jet recording apparatus
Inventor: SUGA MICHIHISA
IPC: B41J2/06
Filed: 1984-05-08
Abstract: PURPOSE:To set voltage applied between a control electrode and an acceleration electrode to a low value, by changing the electric field distribution between both electrodes by a tubular nozzle and injecting ink from a nozzle in such a state that the intensity of an electric field is made strongest at the leading end part of the nozzle. CONSTITUTION:Because a nozzle 102 is projected toward an acceleration electrode 104 in a tubular form, the electric field distribution at a nozzle part is largely disturbed and the intensity of an electric field in the vicinity of the orifice 107 of the nozzle becomes strongest. As a result, the meniscus 111 of the orifice part receives strongest static electricity and attracted toward the acceleration electrode 104 to form an ink droplet. By the effect such that the intensity of an electric field is concentrated to the vicinity of the nozzle orifice, voltage applied between the control electrode and the acceleration electrode in order to form the ink droplet is a value sufficiently low as compared with a conventional one. Because the ink is always drawn out of the orifice 107, the deformation of the ink meniscus applies no influence to the operation of the adjacent nozzle. Therefore, the distance between the nozzle orifice and the acceleration electrode can be made narrower as compared with a conventional one.

Title: Air intake device for multiple cylinder engine
Inventor: HITOMI MITSUO
IPC: F02M35/10
Filed: 1990-03-30
Abstract: PURPOSE:To strengthen the turning-over operation of air intake pressure waves at a volume chamber and obtain an excellent inertia effect, by arranging so that the outer peripheral portion of a rotary valve controlling connection between the volume chamber and each air intake passage by means of rotation, may be projected into the air intake passage at the time of valve closing. CONSTITUTION:A rotary valve 10 is provided within a volume chamber which is at the middle of an independent air intake passage 7, and the control of connection between the air intake passage 7 and the volume chamber is made by conducting the opening/closing rotation of this rotary valve 10. This valve 10 projects into the air intake passage 7 at the time of valve closing, so a crossing portion area with the air intake passage 7 under its valve opening condition becomes large, and its opening portion toward the air intake passage 7 can be made large, and the turning- over operation of air intake pressure waves at the volume chamber at the time of inertia synchronization can be strengthened. Also, under this structure, the effective area of the air intake passage becomes smaller at the same extent with that of the rotary valve 10 portion that projects into the air intake passage 7 at the time of valve closing, but the outer peripheral of the valve 10 is of a circular arc face, so the flow of air intake is smooth.

Title: Piston structure for pressure reducing valve
Inventor: YOKOYAMA TAKESHI
IPC: G05D16/16
Filed: 1987-04-13
Abstract: PURPOSE:To uniformize the gap between a piston and the inside peripheral wall of a cylinder by forming the side face of the piston of a pressure reducing valve into a spherical surface. CONSTITUTION:A piston 101 of the pressure reducing valve is provided with a hole 106 which is extended downward to the center from the top of a spherical body having a diameter slightly smaller than the inside diameter of a cylinder 22, and a piston rod 103 is provided under the spherical body on the same axis as the hole 106. Annular grooves 107 and 108 are worked on upper and lower parts of the outside peripheral surface of the spherical body with the hole 106 as the center, and piston rings 69 and 70 are arranged in these grooves and are elastically energized to the inside peripheral wall of the cylinder from inside by elastic members 71 and 72. A recessed part 10 is provided on the upper end of an upper projecting part 109 of a main valve body 102, and the lower end of said piston rod 103 is fitted to this recessed part 110. Thus, even if the main valve body 102 and the piston rod 103 are guided to the exit side by the fluid passing a valve hole 14 and the piston 101 is inclined, the gap around the inside peripheral wall of the cylinder is always uniformized and the piston is slided in this state because a piston side face 111 is formed into a spherical surface.

Title: Self-priming pump
Inventor: MORI YOUJI
IPC: F04D9/02
Filed: 1982-05-29
Abstract: PURPOSE:To improve the self-priming performance by maintaining the air-tightness through each projection of the impeller and casing thereby making hard the intrusion of air into the swirl chamber and preventing the leakage of liquid while to prevent the fault by eliminating the liquid-seal device, sliding device and check valve. CONSTITUTION:When self-priming, the projections 20a, 20b of the impeller 20 will furnction as the resistor against the intrusion of air while when water enters a gap formed by the projections 20a, 20b, projection 11a of the casing 11 and wall face 11b, the water is sealed by eddy and turbulence to isolate the liquid seal vane 21 and the pump vane 22. Here the balance hole 17b is making hard the intrusion of air into the swirl chamber 23. Consequently the air is hard to enter from the shaft 19 into the swirl chamber 23 to eliminate leakage of liquid thus to improve the self-priming performance. Furthermore since no liquid- seal device, sliding device or check valve is employed, the fault is prevented.
