Title: Solid-state image sensing device
Inventor: NINOMIYA KUNIO
IPC: H04N5/369
Filed: 1988-03-15
Abstract: PURPOSE:To easily enhance a frequency band of a brightness signal by a method wherein a transfer of a vertical transfer shift register is changed over according to whether an image is of color or of black-and white, and an image signal is output from each horizontal output shift register. CONSTITUTION:When a black-and-white image is to be obtained, a transfer at a vertical transfer analog shift register 3 is changed over; each electric charge is shifted to a horizontal output analog shift register 6 of one system. During this process, a transfer clock pulse in the vertical transfer analog shift register 3 is changed over to a four-phase drive; the transfer direction of the electric charge is reversed. When the horizontal output analog shift register 6 of one system is driven at a cycle fs which is three times a switching pulse, a brightness signal which coincides with a time series is obtained from the register 6.

Title: Distributor for heat exchanger
Inventor: GOTO MASAHIRO
IPC: F28F27/02
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To reduce a pressure loss and the consequent increase in power by assembling a plurality of posts at a proper interval while allowing the passage space of a fluid to remain between plates in a distributor that is arranged at the exit or entrance part of the fluid in a corrugate fin type heat exchanger. SOLUTION: A distributor is arranged at either the outlet or entrance part of a fluid in a corrugate fin type heat exchanger and is formed to secure a sufficient pressure resistance strength that can fully withstand a restriction force on assembling by posts S that are assembled between a pair of plates P and P with an arbitrary interval. More specifically, the posts S function as a beam between the plates P and P being arranged at both edges and support a restriction force from upper and lower directions. Also, the posts S have much improved pressure resistance strength as compared with a conventional corrugate plate and the mounting gap, namely the passage space of a fluid, can be sufficiently wide, thus suppressing a pressure loss at the distributor part as much as possible.

Title: Optical wavelength filter and photodetector
Inventor: SAKATA HAJIME
IPC: G02F1/313
Filed: 1989-03-14
Abstract: PURPOSE:To obtain the small-sized optical wavelength filter having a sharp wavelength selecting characteristic and good coupling efficiency by forming a diffraction grating in a region where the respective waveguide modes centering at 1st and 2nd waveguide layers overlap on each other. CONSTITUTION:The optical wavelength filter is laminated with two layers of the waveguide layers (1st waveguide layer 101 and 2nd waveguide layer 102) in the layer direction and a directional coupler by these layers is constituted. Since the respective waveguide layers 101, 102 are so formed as to vary in thickness and compsn., the propagation constants of the respective guided light rays vary. The diffraction grating 107 formed in the 2nd waveguide layer 102 is for selection of the wavelength to be optically coupled and the wavelength region to be selected is determined by the pitch thereof. The shift of the light power generated between the two waveguide layers 101 and 102 by the diffraction grating 107 becomes dominant so that the sharp wavelength selectivity is obtd. Since the shift of the light power is executed in the direction perpendicular to a substrate 103, the coupling length is shortened and the element is miniaturized.

Abstract: PURPOSE:To prevent the wasteful cage calling/registering of a linked operating numbered machine and effectively carry out the conveyance of loading by providing a simultaneous cage calling/registering prohibiting switch in a cage for carrying out a linked operation and prohibiting a cage calling/registering for the linked operation of a numbered machine other than a master car which is responsive to the operation of the switch. CONSTITUTION:As the cage calling for the fourth floor of an A machine which is a master car is operated, a cage calling relay is energized to register the calling for the fourth floor of the A machine and a B machine. Then, a simultaneous cage calling/registering prohibiting switch 6A provided in the cage of the A machine is pressed and cut off, to register the cage calling for the second and third floors of the A machine. In this case, since the switch 6A is kept off, the cage calling relays for the second and third floors of the A machine are energized and, even if the contacts thereof are closed, the cage calling relays 22B, 23B for the second and third floors of the B machine are not energized. Hence, although the elevator of the A machine is stopped on each floor, the elevator of the B machine is directly advanced to the fourth floor without making a stop on each floor.
