Title: Optical space transmission device
Inventor: ASANO TAKESHI
IPC: H04B10/11
Filed: 1992-10-23
Abstract: PURPOSE:To keep the divergent angle of an emitted laser beam constant, and to decrease a fluctuation of photodetecting power by correcting automatically an inter-lens distance between a first and a second lenses to a constant state by a correcting means. CONSTITUTION:When an outer cylinder 2 is subjected to thermal expansion, an inner cylinder 3 is also subjected to thermal expansion, and when the overall length L3 of the outer cylinder 2 extends in the direction as indicated with an arrow (a) by its thermal expansion, the overall length L2 of the inner cylinder 3 extends in the direction as indicated with an arrow (b) being the opposite phase, and an inter-lens distance L1 is corrected automatically. That is, when the overall length L3 of the outer cylinder 2 extends in the direction as indicated with the arrow (a) by the thermal expansion, the inter-lens distance L1 is enlarged in the direction as indicated with the arrow (a). However, as for the inner cylinder 3, since the outer end 3a is a fixed point to the outer cylinder 2, the inner end 3b of the inner cylinder 3 is subjected to phase movement in the direction as indicated with the arrow (b) being the opposite phase to the outer cylinder 2, and the overall length L2 of the inner cylinder 3 extends in the opposite phase in the direction as indicated with the arrow (b). Accordingly, the enlarged portion of the overall length L3 is corrected automatically so as to be cancelled by the enlarged portion of the overall length L2, and the inter-lens distance L1 between a first and a second lenses 4, 5 is held roughly constant.

Title: Ink jet recorder
Inventor: MIZUSAWA NOBUTOSHI
IPC: B41J2/185
Filed: 1986-12-25
Abstract: PURPOSE:To easily and exactly attain the treatment of discharge recovery part without any large displacement of platen and recover part by a method in which the platen and the recovery part are aptly positionally displaced with each other in an interlocking manner to enable them to come near recording head. CONSTITUTION:When a motor 260 is operated, platens 203A and 203B are opened bilaterally through a transmission mechanism and an arm 252 is turned upwards around shafts 253A and 253B. An ink absorber 235 is then pushed up with a case 235A and directly faced with the downside of a recording head 101, thereby permitting discharge recovery treatment by preliminary discharge to be performed. In cleaning the end face including discharge port, arms 251A and 251B are further turned to join the ink absorber 235 with the discharge port of the head 101. Ink adhered to the end face of the discharge port can thus be immediately absorbed by the absorber 235 to allow the recovery of discharge by cleaning.

Title: Microwave oven
Inventor: FUJIKAWA NAOTO
IPC: H05B6/12
Filed: 1988-12-06
Abstract: PURPOSE:To protect a user from being electrically shocked at a portion where a wire is broken or a connector section or a switching device from being destroyed due to abnormal voltage applied thereto by instantaneously stopping the operation of an inverter power supply when a heating unit and the inverter power supply are electrically disconnected from each other while an apparatus is in operation. CONSTITUTION:A high frequency-electric power produced by an inverter power supply 4 is transferred to a heating coil 2 of a heating unit 1 by a transfer means 9. The heating coil 2 generates an alternating field to heat a pan 3 by induction heating. Under the state, when the transfer means 9 is broken or a user erroneously pulls out a connector 11 of the transfer means 9 to disconnect the inverter power supply 4 and the heating unit 1 from each other, the inverter power supply 4 simultaneously stops an output current to be produced therefrom. A wire-breaking detection means 17 detects it and applies an operation-stop signal to a control circuit 8 of the inverter power supply 4 to instantaneously stop the output thereof. Accordingly, the user can be protected from being electrically shocked at the disconnected portion or a switching device 7 is protected from being destroyed.

Title: Drainage pipe cover
Inventor: YANAGAWA SHOJI
IPC: E04D13/08
Filed: 1994-12-13
Abstract: PURPOSE: To obtain a drainage pipe cover which is easily installed without breakage, by forming a clearance between the upperside end face of an inner cylinder and the lowerside end face of a downpipe, in a state that the lowerside end face of the inner cylinder is positioned to contact the fixing part of the outer cylinder. CONSTITUTION: When a drainage pipe cover in which the lower end side face of an inner cylinder 4 is moved down until it comes in contact with the fixing part 10 of an outer cylinder 1, is installed between a downpipe 2 and a drainage pipe 3, since there is a clearance S between the lowerside end face of downpipe 2 and the upper end face of inner cylinder, the drainage pipe cover can be easily installed. After a connecting part 6 has been inserted in the pipe 3, the insertion opening 5 of the inner cylinder 4 is positioned under the downpipe 2 and the inner cylinder 4 is moved up. When projections 8, 8 reach the position of pierced holes 9, the pressing force is released and they are protruded outward into the pierced holes 9, 9 to prevent the cylinder from falling.  Forsible forces do not act on the downpipe 2 and the drainage pipe cover on fitting the drainage pipe cover, as the inner cylinder 4 is fitted while transferring upward. And hence, the lower end thereof is not damaged.

Inventor: STRUSS RODNEY A
IPC: B60H1/32
Filed: 1986-12-26
Abstract: A heat exchanger module particularly suited for vehicular application includes at least two adjacent heat exchangers (12, 14). At least one of the heat exchangers has a side defined by an outwardly opening channel (30, 32) which in turn receives a plastic bar or strip (18, 20). The bar is provided with a plurality of relatively deep recesses (70) which are alignable with holes (40) in the channel. The bottoms of the recesses are sufficiently thin as to be easily penetrable by a threaded fastener extending through the holes in the channel and into the recesses for securing components of the module together and yet are sufficiently thick as to prevent the flow of fluid through the recesses to thereby assure that heat exchange fluid will pass through the heat exchangers.

Title: Intertial negative pressure utilizing type suction aeration apparatus of pipe body
Inventor: TSUCHIDA MASASHI
IPC: C02F3/20
Filed: 1990-11-15
Abstract: PURPOSE:To enhance air suction capacity and to simultaneously perform stirring and the grinding of suspended matter by inserting a blade part in a large diameter pipe body having required length to form a water stream generating structure due to the rotation of the blade part. CONSTITUTION:A blade part 1 is provided to the fanwise part of a water flow path but may be provided in a large diameter pipe body 3 at an arbitrary position. Further, the forming position from an air passage 5 to a suction hole part 6 is arbitrary but desirably set in the vicinity of the fanwise part of the water flow path. The fanwise shape of the water flow path may be gradually or suddenly expanded or may be made slightly narrow. The fanwise part is formed by throttling the end part of a rotary shaft 2 in a conical shape in order to inwardly widen the water flow path. A hole part 6 is provided just in the vicinity of the back surface of the blade part 1 and air is sucked using a suction system utilizing the negative pressure generated at said back surface part, when a streamline body cuts water and the water stream formed at this time is pushed out by the abdominal surface part of the blade part.

Title: Induction heating cooker
Inventor: KAME MASAHIRO
IPC: H05B6/12
Filed: 1990-11-15
Abstract: PURPOSE:To reduce the power consumption by intermittent oscillation and prevent the heating of an inadequate load without deteriorating operability by changing the oscillation stop period during intermittent oscillation in response to the load inadequate state period. CONSTITUTION:The operation of a timer 9 is started when a load detecting circuit 8 judges a load as inadequate. An oscillation controller 7 stops heating, then it again performs a heating action after a preset period is measured by an interval timer 10. When intermittent oscillation actions are repeated for a fixed period of the load detection period shown by the timer 9, the timer 10 measures a preset period longer than the previous preset period, and heating actions are again performed. The oscillation controller 7 performs the intermittent oscillation with the oscillation stop period longer than before by the change of the measurement period of the timer 10. The power consumption is reduced, the overheating of an inadequate load is prevented, and safety can be secured.
