Title: Switching power supply
Inventor: MORITA MAKOTO
IPC: H02M3/28
Filed: 1992-06-09
Abstract: PURPOSE:To operate the apparatus stably, even when a load is lightened, by equipping a switching control means for controlling the switching frequency or duty cycle of a switching circuit through the output of a discrimination means. CONSTITUTION:The apparatus has a PWM control corrector 15 for taking in the induced voltage of a secondary winding as signal and for supplying the control signal to a PWM control IC 3, and when the induced voltage of the secondary winding is inputted to a full-wave rectifier 16, a voltage is generated, if there is output whether the induced voltage of the secondary winding is positive or negative, and reduced to zero, if there is no output. Then, the signal is inputted to an LPF 17 and to the IC 3 converted to DC signal indicating the mean voltage of the signal and lowers a switching frequency when the switching frequency is controlled and can afford little. Therefore, it is possible to obtain a switching power supply causing neither intermittent oscillation nor saturation of a high-frequency transformer, highly responding to a load change, having good conversion efficiency together with low noise and operating stably eve when a load is very light.

Inventor: OOTSUKA YOSHIO
IPC: H01L21/304
Filed: 1981-09-21
Abstract: PURPOSE:To reduce treatment irregularity and to improve the effect of treatment by using wafer retaining jigs combined and repeatedly making the jigs perform inclined motion. CONSTITUTION:A wafer 2 is accommodated in two retaining jigs 1 and fixed with a connecting jig 5. Then, the jigs with the wafer contained therein are immersed in a washing solution contained in a washing container 3'', and afer a certain period of time a handle 6 is provided with reciprocating motion as shown by the arrow, causing the wafer in the jigs to rotate and at the same time to reciprocate. This method of handling, since the wafer is rotated and reciprocated in the treatment solution, provided the wafer with sufficient contact with the solution; therefore, stable treatment is made and the wafer-handling process during the treatment can be simplified.

Title: Automatic drain discharging device
Inventor: IGUCHI JIYUNNOSUKE
IPC: F16T1/00
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To prevent a compressed air from blowing off in a drain discharging method to perform drain discharge for a certain period of time at constant intervals by a cycle timer. SOLUTION: A drain discharging valve 7 is opened using an AND circuit 5 which outputs an ability signal when signals from a check timer 4 and drain sensor 2 are both input. Because drain discharge is made when a drain is sensed and in the cyclic period of drain discharging, such occurrence is prevented that drain discharge takes place even if no drain exists to cause the compressed air to run off.

Abstract: PROBLEM TO BE SOLVED: To form a fine resist pattern, whose section is in a reverse-tapered shape by exposure due to single UV exposure or drawing due to electron beams by depositing metal on the upper surface of a substrate at a side, where a resist film is formed and peeling the metal being deposited on the upper part of the resist film for each resist. SOLUTION: A pattern 3, where the section of a resist that becomes an etching mask for forming a gate electrode, is in a reverse-tapered shape is formed (b). Then, recess etching is made using phosphoric acid liquid through an opening, and a groove 4 is formed on the surface of a substrate (c). A sidewall angle after etching can be controlled by the composition of the etching liquid and etching time at this time. A metal wiring layer for the gate electrode is deposited over the entire surface on the substrate where the groove 4 is formed (d). Then, the resist and an unwanted metal wiring layer on it are eliminated by the lift-off method, while leaving a part that is deposited on the bottom surface of the opening out of the metal wiring layer (e). A part that is deposited on the bottom surface of the opening becomes a gate electrode 5.

Title: Coated material with excellent resistance to dirt attaching property and its production
Inventor: TSUBURAYA HIROSHI
IPC: B05D7/00
Filed: 1995-05-24
Abstract: PURPOSE: To provide a coated material with excellent resistance to dirt attaching property by setting a paint film surface, so that the surface layer part of the paint film provided on the surface of a material to be coated is removed and the paint film has a surface shape in which both surface length rate shown by the ratio of in-plane rectilinear distance to a bath surface distance and 10 points average roughness have a specific value respectively. CONSTITUTION: For example, in the case of continuously coating a coil-shaped metal plate, the metal plate under cooling or after cooling is polished by a buff roll, a brush roll, a grindstone, etc. Further, in the case of a coated molded form such as an external wall panel and an existing coated material, a paint film after cooling is polished by a rotary polisher. At this time, a paint film surface having large surface free energy is formed. In this case, the paint film surface is set up, so that paint film has surface shape in which surface length rate S1 shown by the ratio of in-plane rectilinear distance L1 to a bath surface distance L2 exceeds 100.04% and 10 points average roughness Rz is >=0.25. Thereby, a coated material is obtained in which hydrophilicity of a paint film surface is increased and resistance to dirt attaching property is excellent.

Abstract: PURPOSE:To obtain a magnetic recording medium which has the magnetic properties suited to the high-density recording and can withstand the repetitive use, by introducing the oxygen gas only in the early process when a ferromagnetic thin film is formed on the base material by the cluster ion beam deposit method. CONSTITUTION:A high vaccum state is secured within the vaccum tank 1 via the exhaustion port 13, and then the electric conduction is given to the electrode 213. Then the sealed-up crucible 211 is heated up to increase the vapor pressure of the ferromagnetic evaporation source material 6 within the crucible 211 as well as tube 3. The vapor of the material 6 is jetted into the tank 1 through the jetting hole 212 and then receives an over-cooling by the heat insulation expansion, thus forming a cluster. The heat electron discharged from the filament 221 of the ionizing device 22 is accelerated by the mesh-type electrode 222 to have a collision against the cluster and the oxygen molecule and then to be ionized. The cluster ion and the oxygen ion generated are accelerated by the acceleration electrode 23 and then jetted onto the base component 5 to form a thin layer of the metal oxide on the component 5. The introduction of oxygen is discontinued when the thickness of the thin layer reaches the prescribed value, and then only the cluster ion beam deposit is carried out.
