Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To provide an information processor with litte noises without special additional circuit required by controlling a digital signal processing means so that load fluctuation is relaxed or the load is dispersed within a time of one frame processing. SOLUTION: During the time when a recording mode is continuing, an interruption signal is inputted to a digital signal processing part 5 from a main controller 11 at each frame period, and one frame operation starts at is point in time. In a recording mode (REC mode), encoding processing is carried out, and after this processing is complete, a 1st virtual arithmetic operation is performed and the device becomes to be of an interruption waiting state. On the other hand, in a reproducing mode (PLAY mode), decoding processing is carried out instead of encoding processing, and the device becomes to be of an interruption waiting state. Thus, the main controller 11 controls the digital signal processing part 5 so that load fluctuation is relaxed or the load is dispersed within a time of one frame processing.

Title: Soot blower device
Inventor: CHIYAARUZU UESURII HAMONDO
IPC: F28G3/16
Filed: 1984-09-10
Abstract: A sootblower of the long retracting variety including a drive system (16) which simultaneously rotates the lance tube (12) as it is inserted and withdrawn from the boiler. A variable speed drive is employed to modulate the rotational speed of the lance tube in accordance with the projected distance of the lance tube such that the lance tube is driven faster at intermediate lance tube projected distances thereby optimizing the cycle time of the sootblower. The modulated rotational speed of the lance tube is maintained at all projected distances below the critical speed which varies as a function of projected distance and the sootblower type. By driving the lance tube at certain projected distances at a rotational speed above the critical speed for other projected distances, the translational speed is increased and cycle time reductions are realized as compared with the prior art wherein the lance tube is driven at a constant speed below the minimum critical speed. The lance tube speed may be varied upon retraction and operated at constant speed for insertion or vice-versa or the speed may be varied both on insertion and retraction, as the cleaning requirements of a particular application requires.

Title: Discharge lamp lighting device
Inventor: TSUGITA KAZUHIKO
IPC: H05B41/42
Filed: 1989-07-21
Abstract: PURPOSE:To ensure lighting of a lamp even if replaced in a power switch-on state by connecting reset circuits, which allow preset-time discharge of a timer capacitor in a start control circuit, to a d.c. power supply via the pre-heating cathode of each lamp. CONSTITUTION:When a power switch 20 is kept in ON and a new fluorescent lamp 3a or 3b is mounted, reset circuits 37a, 37b are connected to a d.c. power supply 1 to allow transistor(Tr)s 41a, 41b to turned on and a power supply for a capacitor 23 to be discharged for a moment. A (Tr) 33 is thus off in a preset time while the capacitor 23 is charged up whether a light adjusting switch 19 is on or off. (Tr)s 31a, 31b in an oscillation frequency control circuit 15 can therefore continue to be on in a preset time after the lamp 3a or 3b is mounted, and so the lamp 3a or 3b is started in a fully lighted state. When either the lamp 31a or 31b is displaced, making the switch 20 causes the lamp 3a or 3b to be lighted on and to be light-adjusted through on-off operation of a switch 19.

IPC: B23B27/14
Filed: 1985-08-28
Abstract: PURPOSE:To reduce breakage of a tip shank of a micro drill for perforating a number of perforations in a printed wiring substrate by coating the tip shank with a material having a hardness lower or a tenacity greater than the material of the drill body. CONSTITUTION:In a small type drill, a tip shank B is coated with a metal such as Co, Ni, Cr, W or the like, or any alloy thereof, when the material of the drill body 4 is a super hard alloy; when it is sintered diamond, the tip shank B is coated with a carbide or a nitride of Ti, Zr, Ta, Nb or the like having a hardness less than sintered diamond. This makes the outer surface smooth and facilitates ejection of chips. Too small thickness of the coating layer 3 is not effective, while too great thickness deteriorates cutting property, and the thickness from 0.2-50mum is advisable. The tip shank coated under the above conditions can be used for perforation of a substrate of fiberglass reinforced epoxy resin, quartz fiber reinforced polyimide or the like.
