Title: Finned heat exchanger
Inventor: SUGAWARA TAKASHI
IPC: F28F1/32
Filed: 1987-10-16
Abstract: PURPOSE:To significantly lengthen the time interval in which the space between the fins is clogged so as to prevent the reduction of the heat exchanging rate by providing multiple heat transmission pipes which perpendicularly intersect multiple and parallel plate fins, and disposing a semi-circular cutout in the fin near to the heat transmission pipe on the upstream side relative to the air flow. CONSTITUTION:Since a semi-circular cutout 7 is disposed near to a heat transmission pipe 2, the frost cannot grow there, preventing the frost 4 from growing on the fin leading edge 3, and so, the clogging between the plate fins 5 can be prevented, causing the frost 4 to uniformly form on the fin surface. Therefore, the time interval in which the space between the plate fins 5 is clogged can be significantly lengthened, and the heat pump operation time can be significantly extended. Moreover, since the mixing takes takes place between the flows across plate fins 5 through the cutout 7, the heat transfer rate on the fin surface is improved, which is great enough to compensate the lost fin surface area due to the cutout 7, and an equal amount of heat exchange quantity to one which does not have the cutout 7 can be obtained.

Title: Measuring apparatus of distance for vehicle
Inventor: KOSHIZAWA TOSHIBUMI
IPC: G01S17/93
Filed: 1990-09-28
Abstract: PURPOSE:To keep a range of measurement of stain of nonreflection type protective glass, such as a rain drop or dust, to be side and thereby to prevent deterioration of performance, such as deflection or false measurement, by driving a wiper when the state of reflection of light of the glass is detected from input of the light thereto and output of the light therefrom. CONSTITUTION:A light outputted from a light source 9 is transmitted normally through protective glass 1 having a nonreflection characteristic and is not inputted to a light-sensing element 10. Accordingly, an input to a comparator 11 is of low level and a wiper motor 3 is not driven. A light of a laser pulse outputted from a laser light emitting element 5 and reflected from an onject in this state is detected by a laser light sensing unit 6 and a distance to the object is calculated from a time of propagation by an arithmetic circuit 7. When a rain drop, dust or the like sticks on the glass 1, the light of the light source 9 is reflected thereby, an output level of the element 10 turns to be high and exceeds the reference of the comparator 11 and the motor 3 makes a wiper 2 operate. When there is a sticking substance on the glass 1, accordingly, it is wiped by the wiper 2 and interception or diffusion of an input-output light of the light emitting unit 5 and the light sensing unit 6 are prevented.

Title: Multiple-wavelength semiconductor laser
Inventor: OKUDA MASAHIRO
IPC: H01S5/00
Filed: 1988-10-20
Abstract: PURPOSE:To enable optic characteristics of a laser beam of different wavelength to be oscillated from each active stripe region by allowing the reflection rate on a resonator edge surface owned by each active stripe region to be different. CONSTITUTION:A low-reflection film 3 is coated to the rear-edge surface which is one of the reflection surfaces constituting a resonator of an active stripe region 1 and a high-reflection film 4 is coated to the rear-edge surface of one of the reflection surfaces of an active stripe region 2. Thus, since reflection loss is small in the stripe region 2, oscillation occurs even if the current injected there is small, thus achieving oscillation at a quantum level with low energy level. On the other hand, reflection loss becomes larger at the active stripe region 1 and large amount of current needs to be injected to achieve oscillation. Thus, the semiconductor laser unit is formed in one piece within one element and each semiconductor laser unit can be so structured as to improve optical characteristics including astigmatism and near field pattern and less variations without being affected by selection of wavelength.

IPC: B65H67/06
Filed: 1986-11-07
Abstract: PURPOSE:To efficiently select the storing place of a coil by controlling a coil yard plane by two-dimensional coil position coordinates, making intervals between coil positions in the Y-axis direction variable in accordance with the large and small divisions of the outside diameters of coils, and enabling the same lot of coils to be adjacent in the Y-axis direction. CONSTITUTION:By controlling the plane of the storing place of a coil yard with the two-dimensions of X-axis and Y-axis, the accuracy of grasping the arrangement of coils is improved, improving the operation efficiency for an operator to find out a designated storing place. And, by making the coil arranging interval DELTAY in the Y-axis direction variable in accordance with the large and small divisions of the outside diameters of coils, the DELTAY can be made smaller when the outside diameter of a coil is small, enabling the determination of storing places at the arranging interval corresponding to the outside diameter of a coil. Also, the storing place is determined so that the coils of the same lot can be placed adjacent to each other at the arranging interval of the coils in the Y-axis direction. However, when there is a placeable space for the placing space of plural number of coils in the Y-axis direction, different lots of coils can be placed leaving a space of a defined distance. Thereby, the storing place can be smoothly operated.
