Title: Heat exchanger
Inventor: ITO MASAAKI
IPC: F24F1/00
Filed: 1987-05-22
Abstract: PURPOSE:To reduce draft resistance by causing air flowing slantingly to a heat exchanger to flow out without changing forcibly its flow direction by a method wherein the row direction of pipes and the rising lines and folded lines of slits cut and raised on a fin surface are slanted to the edge of the fin. CONSTITUTION:A large number of pipes 2 are inserted into a fin 1 at right angles. The row direction of the pipes makes an angle of beta to the edge of the fin. The size of beta is larger than 60 deg. for staggered arrangement of equilateral triangles and smaller than 90 deg. for a checkerboard arrangement. On the fin surface a large number of slits 3 are cut and raised. The rising line 4a and folded line 4b of the slit are together in parallel to the row direction of the pipes and make an angle of beta to the edge of the fin. Thereby, inflow air 6 flows in the direction of the pipes and are hardly bent and becomes outflow air 7 to flow away. When the air passes through over the fin surface, the air is in contact with a large number of slit edge surfaces 5 to promote heat exchanging.

Title: Hybrid power source switching device
Inventor: OSADA NORIAKI
IPC: H02J9/06
Filed: 1988-05-23
Abstract: PURPOSE:To minimize momentary power interruption and cross-flow between power sources by varying ON timing of a thyristor switch corresponding to voltage fluctuation of a standby power source when the power source is switched. CONSTITUTION:When switching is made from a normal power source 2 to a standby power source 1, output from an operational amplifier 305 increases with higher rate than the rated voltage if the voltage of the standby power source 1 is higher than the rated voltage. At the time point when the output from the operational amplifier 305 exceeds over a reference voltage 307, output from a comparator 306 changes from '0' to '1'. The output is transmitted as an output signal from an ON/OFF time control circuit 23 to a gate circuit 8 thus turning a thyristor switch 6 ON quickly when compared with the case of rated voltage. Switching time of an electromagnetic contactor 7 is lengthened when the voltage of the standby power source 1 is lower than the rated voltage, but the thyristor switch is turned ON slowly through the ON/OFF time control circuit 23 when compared with the case of rated voltage.

Title: Magnetic card and its information reading method
Inventor: ASUKE HISASHI
IPC: G11B19/20
Filed: 1992-05-18
Abstract: PURPOSE:To enable the recording of fixed information simultaneously with subtraction information and to improve a security property by forming magnetic patterns of combinations of magnetic materials having specific coercive forces on a track indicating the subtraction information. CONSTITUTION:The magnetic patterns consisting of the combinations of magnetic bars A13 which are the magnetic material having the coercive force lower than the coercive force of external magnetic fields at the time of information reading and are saturated by the external magnetic fields of a prescribed value or below and the magnetic bars B14 which are the magnetic materials having the coercive force lower than the coercive forces of the external magnetic fields and are satd. by the external magnetic fields of a prescribed value or above are formed in the punched track indicating the subtraction information. The adequate reading is, therefore, not possible unless both values of bias voltage values and slice levels are adjusted. Then, it is difficult for a forger to find out a plurality of the combinations of the bias voltage values and bias levels effective for reading and there are no chances for the forger to know the presence of the fixed information. Since the subtraction information and the fixed information coexist in proximity, the security property is improved.

Abstract: PURPOSE:To make the detection of short-circuiting failure between photoelectric conversion elements possible by providing a means for unequlizing the quantity of light entering each of the photoelectric conversion elements (sensor bit) between the photoelectric conversion element and a light source. CONSTITUTION:Light is projected to the light receiving section of a one- dimensional line sensor 4 from a light source 1 through a diffusing plate 2 and a light shielding mask 3. The mask 3 is triangularly formed in its opening part., and the severally different quantity of light is thereby projected to the light receiving section of each of adjacent bits. Owing to the mask 3, a sensor output having a level difference as the output of the adjacent bit can be obtained as the output of the sensor 4 in a normal chip. In the case where short-circuiting failure exists between the adjacent sensor bits, a sensor output wave form obtains an output wave form having no level difference between the adjacent bits. Namely, since the outputs from the adjacent sensor bits becomes the same level output, the existence of short failure between the sensor bits can be confirmed by reading in a voltage difference and discriminating it.
