Title: Film scanner
Inventor: NISHIKAWA MASAHARU
IPC: H04N1/19
Filed: 1989-07-27
Abstract: PURPOSE:To decrease the floor area of the scanner and to make the size small by adopting the constitution such that a lighting optical system and a read optical system are formed stereoscopically in the vertical direction. CONSTITUTION:Lighting optical systems 51-56 and read optical systems 72-75 are arranged stereoscopically in two vertical directions while having an original moving base 61 in-between. In comparison with the case that the lighting optical systems and the read optical systems are formed on one and same plane, the floor area of the scanner is reduced. Moreover, since a film original is supported to the original moving base in the horizontal state, the loading/unloading of the film original is facilitated. Furthermore, since the lighting optical system is exposed by opening a movable cover 45, various components accommodated in an upper container are easily accessed to facilitate the job such as mainte nance.

Title: Cooling device of board
Inventor: HARA TAKASHI
IPC: H05K7/20
Filed: 1993-07-12
Abstract: PURPOSE:To enable a board to be so cooled down in a short time as to be nearly uniform in temperature distribution by a simple structure. CONSTITUTION:Cooling water is fed through a cooling water inlet hole 2 provided to the center of a cooling plate 1, made to flow through a water channel 3, and discharged out through cooling water outlets 4 and 5 provided to the periphery of the cooling plate 1. By this setup, as the center of a mounting pad is lower than its periphery in temperature, a board mounted on the mounting pad can be cooled down as it is compensated in temperature distribution, and thus the board can be so cooled down as to be nearly uniform in temperature distribution.

Title: Radio direction finder
Inventor: OKUBO TAKEHIKO
IPC: G01S3/54
Filed: 1986-08-20
Abstract: PURPOSE:To obtain clear direction in finding sound source only by a filter circuit by making it possible to successively bring click sound due to change-over itself to the outside of an audible sound region, by setting the output due to the reciprocating cycle of the successive change-over of each receiving signal of an antenna to the frequency of the audible sound region for direction finding. CONSTITUTION:A change-over circuit 12 successively performs the reciprocating change- over of receiving signals of antennae 10A-10E from one end to the other end to output a change-over searching signal 12a. A change-over wave circuit 13 generates, for example, a rectangular wave signal having frequency approximate to autible frequency as a change-over signal 13a for allowing the circuit 12 to carry out change- over. A selecting and amplifying circuit 14 selects the frequency and band of a radio wave for direction finding and outputs the signal 12a while amplifies the same to desired output. An FM detection circuit 15 detects the FM signal in a receiving signal 14a to output the same as a detection signal. A filter circuit 16 obstracts the band part higher than audible frequency in the signal 15a to generate a low frequency signal 16a which is, in turn, outputted by a speaker 17. An AM detection circuit 18 outputs a low frequency signal 18a when a detected radio wave is amplitude modulation.

Filed: 1988-08-06
Abstract: PURPOSE:To house a large semiconductor element in a small package and contrive a high integration of a semiconductor device by disposing internal leads on the semiconductor element after forming a die pad and leads separately by the use of double lead frames. CONSTITUTION:A semiconductor element 11 is located and fixed on a die pad part 12. Internal leads 13 extend inside on the upper face of the element 11 and, through bonding wires 15, the internal leads are connected to electrodes 14 which are installed at the pointed ends of the leads 13 and at peripheral parts of the element 11 and are corresponding to the leads 13. The whole body is sealed with a resin and the sealing resin exists between the lower face of leads 13 and the surface of the element 11. It is sufficient for the width C of the element 11 which is sealed inside of an envelope having a width N to satisfy the relationship of C<N-alpha' where (alpha') represents margin of dimension. However, as the value of (alpha') becomes small in comparison with that of N, the value of N approaches considerably the value of C and then, scalling up of the element is obtained. Such a state of the element contrives a high integration of a semiconductor device.
