Title: Air purifier
Inventor: MARUI YASUO
IPC: B01D46/00
Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To prevent malodor held in stains captured by a filter from being released into a room by installing before a filter a front panel, which opens or closes an air suction port when a drive motor of a ventilation fan is set to ON or OFF. SOLUTION: If a synchronous motor 18 turns through certain angles, a crank 16 engaged with a hook 17 turns forward about a bearing 3b of a guide panel 3 against normal conditions of a spring 13 and indoor air is drawn from the side of entire circumferences of a slide panel 9 and the panel. 3, which air is passed through a filter 20 and purified, and discharged into a room from an air delivery port 25 of a rear case 2 by means of a sirocco fan 8. And if a motor 6 stops, the motor 18 becomes free and a restoring force acts on the stretched spring 13 to retract the panel 9 and the crank 16 also returns to its original position to close a gap between the panel 9 and the panel 3.

Inventor: IIZUKA KIYOSHI
IPC: G02F1/13
Filed: 1986-11-25
Abstract: PURPOSE:To switch a soft and a sharp image without changing filters by sandwiching a liquid crystal layer which changes in orientation by being applied with an electric field between substrates as a liquid crystal optical phase member, providing a rotatable polarizing plate nearby this member, and adjusting the electric field application and the angle of the polarizing plate. CONSTITUTION:The liquid crystal optical phase filter consists of the liquid crystal layer 9 which changes in orientation according to whether or not an electric field is applied, two transparent electrodes 7 and 8 which apply the electric field to this liquid crystal layer, and the polarizing plate 16 which controls luminous flux incident on or projected from the liquid crystal layer. Opening parts 7a which are distributed at random are formed in at least one transparent electrode between those two transparent electrodes 7 and 8 and the polarizing plate 16 is made relatively rotatable to the liquid crystal layer to control the birefringence of the liquid crystal layer and the polarized component ratio of the incident light to or projection light from the liquid crystal layer, thereby varying a modulation Transfer Function MTF value optionally. Consequently, when this filter is mounted in front of a camera lens once, a soft and a sharp image can be switched without detaching the filter.

Title: Switching power circuit
Inventor: YASUMURA MASAYUKI
IPC: H02M3/28
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent abnormal operation of a switching element meeting the reverse recovery time of a clamp diode. SOLUTION: Clamp circuits 2 (2A, 2B) provided for a self-excited resonance converter is formed out of Schottky barrier diodes DSBD (DSBD1, DSBD2) and resistors RD (RD1, RD2). This prevents a period for reverse recovery time from being formed after completion of a damper period at the time of turn-on of switching elements Q1, Q2. The respective switching elements Q1, Q2 are controlled to be ON after completion of the damper period. It is thus possible to prevent generation of abnormal switching operation even at the time of stable operation or under a condition of heavy load and low AC input voltage.

Filed: 1990-10-18
Abstract: PURPOSE:To suppress the influence of a grounding body outside a discharge tube and stabilize a discharge voltage upon aerial discharge in the case of high voltage discharge by deflecting and setting a discharge gap position to one line-electrode side. CONSTITUTION:Line-electrodes 12, 14 are soldered at both ends of a cylindrical ceramic enclosure 10, followed by charging an innert gas therein.

The outer surface of the enclosure 10 is fixed to a grounding body 18 via an adhesive 16 having electrical insulating property. Consequently, the dispersed variation in the discharge voltage seldom occurs and stable discharge can be obtained, and the influence caused by the grounding body can be minimized to a low level for practically yielding no problem. And starting characteristics of any engine can be effectively improved by applying this effect to ignition plugs for the engine.

Title: Control method of extruding machine
Inventor: TAGUCHI MASARU
IPC: B29C48/03
Filed: 1987-11-05
Abstract: PURPOSE:To obtain a stable extruding rate, by a method wherein an electric current value of a screw motor performing melting and extruding is detected, the signal of which is compared and operated at a PID control part having a reference electric current value determined beforehand and a loading of raw materials into an extruding machine is controlled. CONSTITUTION:An electric current value of a screw motor obtained at the time when a stabilized extruding state is obtained through manual operation is decided as an established value of a PID controller 10 by changing over an automatic/manual changeover switch 13 of a feeder 4 to a manual speed instruction setting instrument 12. Decision of stability on a control/extruding state of encroaching stability of the raw materials upon the screw in this instance can be performed even with a signal through a pressure senser convertor 14 of a head part of an extruding machine 1, therefore, the electric current value of the screw motor can be decided by adding this value also. When the electric current value of the screw motor, which is a desired value of the PID controller 10, is decided, automatic changeover control of the automatic/ manual changeover switch 13 is performed. With this control, a fixed starved feed state (which is possible by controlling output of the feeder 4) can be kept on and a stabilized good product can be obtained.

Abstract: PURPOSE:To prevent the growth of frost at the leading edge of the fin and the fin around heat transfer tubes and prevent reduction of heat exchanging amount by a method wherein the fin, located at the upstream side of airflow through the heat transfer tubes, and the same, located at gaps between the heat transfer tubes, are provided with multiple cut-out sections. CONSTITUTION:The fin 6, located at the upstream side of airflow through the heat transfer tubes 2, and the fin 8, located at the gap between the heat transfer tubes in the direction of the step thereof, are provided with the out-out sections 7, therefore, these parts will never be frosted. As a result, the growth of frost at the leading edge 3 of the fin and the fin around the heat transfer tubes is prevented, the surface of the fin is frosted uniformly and a blockading time due to clogging between plate fins by frosting is extended remarkably and the operating time of heat pump may be elongated remarkably. On the other hand, the mixing effect of flow is generated at the cut-out section 7 between neighboring fins, therefore, the heat transfer coefficient of the surface of the fin may be improved and heat exchange of the same degree as a heat exchanger having no cut-out section may be effected.
