Title: Antireflection composition and formation of resist pattern
Inventor: NISHI MINEO
IPC: G03F7/004
Filed: 1995-10-23
Abstract: PURPOSE: To obtain a compsn. which is usable as an antireflection film, allows the formation of a coating film with an aq. medium, etc., and has good step coverage even with a small film thickness by incorporating a polyvinyl alcohol(PVA) resin of a specific saponification rate into the above compsn. CONSTITUTION: The antireflection compsn. applied between a substrate and a photoresist film contains the PVA resin having the saponification rate of >=70%. This saponification rate is a value expressing the ratio of the hydroxyl group by mol%. The PVA resins having various properties by these saponification rates are known. The developer resistance at the time of, for example, developing is poor and the mixing with the photoresist film arises if the saponification rate is <=70% and, therefore, such rate is undesirable. The higher saponification rate yields a better result in the developer resistance and the more preferable saponification rate is >=75%. Conversely, the preservable property of the compsn. tends to degrade (leads to the production of insoluble foreign matter) if the hydrolysis rate is too high. The saponification rate is preferably <=99% and further preferably <=98%.

Title: Garbage receiving housing
Inventor: INATANI MASATOSHI
IPC: A61L9/015
Filed: 1988-10-31
Abstract: PURPOSE:To safely and effectively deodorize raw garbage, in a garbage receiving housing having an ozone generator, by generating ozone from the ozone generator when the pressure equal to or more than the predetermined weight of an inner box is detected by a pressure sensor. CONSTITUTION:When garbage is thrown into an inner box 9, this state is sensed by a pressure sensor 21, and the first electromotive fan 14 and an ozonizer 13 begin to operate. At this time, the recirculation stream of ozone passing through a screen 23 from a receiving housing 6 and irradiating the garbage in the inner box 9 from the jet port 25 of the ozonizer is formed by the first electromotive fan 14. Ozone is decomposed into oxygen and an oxygen radical while the latter is reacted with a malodorous component to promote the decomposition of a malodor. By generating ozone from the ozonizer 13 when the pressure equal to or more than the predetermined wt. of the inner box 9 is detected by the pressure sensor 21, deodorizing effect is improved and it is unnecessary to generate ozone in a necessary or more amount and safety is secured.

Title: Toner hopper
Inventor: TABATA YOSHIAKI
IPC: G03G15/08
Filed: 1990-10-12
Abstract: PURPOSE:To accurately detect a no-toner state by outputting a no-toner signal when a signal generated by detecting a no-toner level being reached is outputted and a signal generated by detecting the rotation of an agitation blade is outputted. CONSTITUTION:When the level of the toner becomes lower than a level l1, the agitation blade 5 is rotated with the elastic restoring force of a leaf spring 6 against the current agitation resistance. At the same time, a photointerrupter 9 outputs a signal regarding the rotation of the agitation blade 5 and a CPU detects the rotation of the agitation blade 5. When the level of the toner reaches the no-toner level l1 by the rotation of the agitation blade 5, namely, decreases below the detection end 7a of a piezoelectric sensor 7, the piezoelectric sensor 7 stops outputting the signal. Then the CPU detects the state wherein there is no toner in the hopper case 2.

Abstract: PURPOSE:To release automatically the middle of a mechanism, when a back operating part becomes a lock state in the course of a loading operation, and to prevent exactly a lock of a motor side by providing releasable part in the middle of the mechanism. CONSTITUTION:In a position where a cassette is attracted up to its last part, an eject plate 3 is engaged to an eject gear 2, advances as one body with an eject rack plate 4, and the cassette descends to a mode position. At the time point when the descent is completed, a swing gear 1 reaches an intermittent part of the eject gear 2. The eject gear 2 is turned a little by a turning means provided on the lower part of the gear, and thereafter, stopped, and a loading operation is completed. In the course of the loading operation, in case the eject plate 3, the eject rack plate 4, etc. becomes a lock state due to a fact that the cassette is caught on a part of the mechanism, a load applied to a loading gear plate 11 increases, and a force of an escape direction becomes larger than a force of a spring 12, therefore, said plate 11 causes an escape operation of an engagement,and the engagement of loading gears A-D and a fly wheel is released.

Title: Lever structure of impact dot head
Inventor: SHIMOMURA MASAKI
IPC: B41J2/24
Filed: 1987-10-30
Abstract: PURPOSE:To obtain a lever by which high speed printing can be performed at low power consumption, by a method wherein a ratio of an arm part plate thickness to an armature part plate thickness is made a specific value. CONSTITUTION:A wire 2 is fixed to a wire fitting part at the top of a lever 1, and the lever 1 can be rotated within a certain angle centering a fulcrum shaft 11. When current is applied to a coil 8, a magnetic circuit composed of a frame 7, a yoke 9, a yoke 10, and a lever 11 is constructed, magnetic suction force acts on an air gap between (D) and (E), and the lever 1 rotates in the arrow A direction. The wire 2 fixed to the top of the lever 1 is projected thereby to transfer ink onto a printing paper 6 via an ink ribbon 5, and printing is performed. Since an armature part (C) has a role as a magnetic path component, a plate thickness t2 is made so thick that magnetic flux can easily pass therethrough. Then, since moment of inertia around a fulcrum of the lever is necessarily made small so that an arm part (B) and a wire fitting part (A) can follow high speed printing operation, a plate thickness t1 is so shaped as to be not more than two-fifths of the armature part plate thickness t2.

Title: Solenoid device
Inventor: MAENISHI KOZO
IPC: H01F7/16
Filed: 1989-10-23
Abstract: PURPOSE:To improve stroke/attraction characteristics by use of a simple constitution and simplify manufacturing, by installing a plunger on the coil axis of an electromagnet so as to be able to move along the axis, and arranging a cylindrical magnetic auxiliary plate in front of the plunger on the coil axis, which plate has a taper part becoming narrower toward the planger side. CONSTITUTION:When an electromagnet 8 is excited by conducting power in a coil 4, a closed magnetic path is formed, and the attraction of a plunger 9 is generated, so that the planger moves forward along the axis coping with the spring force of a restoring spring 17. When the power conduction is released, the attraction disappears, and the plunger returns to an initial position by the effect of spring force. A magnetic auxiliary plate 16 is arranged in front of the plunger 9, and restrains the decrease of the attraction according to the amount of stroke by the magnetic flux passing the magnetic auxiliary plate 16. When the plate 16 is equipped with a taper part 18a wherein the width becomes narrower toward the plunger 9 side, the amount of passing magnetic flux has an increasing tendency in a stroke range D, and strong attraction is maintained, which range reaches from the position where the tip of the plunger 9 approaches the narrow width end 16b of the taper part 16a to the position where the tip approaches the wide width end 16c.

Abstract: PURPOSE:To alleviate brake impact at the time of quick turning and to suppress variation of centrifugal acceleration in a motor loading/unloading vehicle such as forklift by providing a plugging brake means and a quick turn detecting means thereby lowering the plugging brake force of a travel motor upon detection of quick turning. CONSTITUTION:At the time of plugging brake, a regenerative contactor MG in a traveling circuit 9 is closed at first and drive/reverse contactors MR, MF are switched to the opposite side as compared with powering time thus imparting torque on a travel motor in reverse direction.

The plugging set current at the time of quick turning is set lower than that at straight advancing. A current detected through a current sensor 4 is then compared with a set current and the brake force is regulated according to the duty ratio of gate voltage to be applied on a transistor TM.
