Title: Heat exchanger for recovering latent heat
Inventor: TSUJIKAWA SHIGEO
IPC: F28F19/02
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To prevent generation and progress of corrosion over a long term by coating the outer surface of a heat exchanger for recovering latent heat with an n-type transistor, i.e., titanium oxide, and providing an apparatus for projecting light or sun beam to the coated surface of the heat exchanger. SOLUTION: Water from a water supply pipe 8 enters through a main heat exchanger 4 into a heat exchanger 5 for recovering latent heat where it is warmed by the sensible heat and the latent heat of exhaust gas. Hot water thus produced is further heated by a heat exchanger 9 up to a set temperature before being delivered through a hot water supply pipe 10. In such a hot water supply apparatus, a titanium oxide coating layer is formed on the heat exchanger 5 and a light source L is disposed obliquely above the heat exchanger 5. The light source L employs a spherical light source arranged with a reflector R on the back thereof. Water on the surface of the titanium oxide coating is oxidized by projecting light from the light source L to generate oxygen thus preventing corrosion of the heat exchanger 5 permanently.

IPC: B60K28/16
Filed: 1991-12-27
Abstract: PURPOSE: To control spin of a vehicle driven by an internal combustion engine.

Filed: 1993-12-27
Abstract: PURPOSE:To mechanically stabilize, prevent the generation of peeling off and cracks caused by difference in coefficient of thermal expansion, increase freedom of material selection, and reduce cost by forming am electrically insulating layer with an organic metal polymer. CONSTITUTION:In a heating roller obtained by forming an electrically insulating layer 13, a heating resistant layer 15, and a surface-covering layer 17 in order on the outer surface of a metallic cylindrical base body 11, the layer 13 is formed with an organic metal polymer.

Title: Magnetic card issuing method
Inventor: KITAMURA MITSURU
IPC: G06K13/103
Filed: 1993-12-28
Abstract: PURPOSE:To eliminate magnetic recording with wrong bar code information and prevent a defect in card issue by detecting simultaneous insertion before bar code information is read out and reversely sending and returning 2nd and succeeding cards when the simultaneous insertion is detected. CONSTITUTION:When unrecorded cards 6 are stacked on an unrecorded card stack part 11, the top card 6a is sent to a write part by a taking-in roller 15 through a card conveyance path 4. At this time, if the 2nd card 6b is taken in accompanying the 1st card 6a, a sensor 20 detects it and reverses a motor 18. The 2nd card 6b is sent reversely by the taking-in roller 15 and put back to the unrecorded card stack part 11. Therefore, the magnetic information of the 3rd card 6c is prevented from being written on the magnetic stripe of the 2nd card 6b by reading the bar code of the 3rd card 6c by a bar code reader by mistake instead of a bar code.
