Inventor: KANEDA REIKO
IPC: G06F9/45
Filed: 1988-10-17
Abstract: PURPOSE:To enable speedy retrieval processing and conversion processing by using information generated by digitizing a name and narrowing down a retrieval range when the name is retrieved so as to convert the call name of a subroutine that a system offers into the same format of an external entrance name. CONSTITUTION:The call name of the subroutine D needs to be present in a translation format C while converted into a determined name format which becomes an external entrance name so that the call name is combined with the translation format C by combining processing E. Here, the call name of the subroutine D is retrieved among names of a source program A and converted into the name format of the external entrance name. Then processing for cutting each name into an external name and an internal name is performed in the 2nd phase (b) of the translation processing B, so the retrieval processing is performed in the 2nd phase (b) to reduce the range of the retrieved object from all names to only the external names. Consequently, the retrieval and conversion are speeded up.

Title: Automatic ticket examination machine
Inventor: KITAZAWA TAKAYUKI
IPC: G07B15/00
Filed: 1996-10-02
Abstract: PROBLEM TO BE SOLVED: To surely secure the proofs of wrong rides of trains without paying for middle section by providing a ticket examination machine with a write means which writes the wrong use frequency on a commutation ticket and a sending means which sends the owner data to other stations to specify the owner of the commutation ticket when its wrong use frequency reaches a prescribed level. SOLUTION: When a user puts a commutation ticket A into the automatic ticket vending machine at station (a), the data recorded on the ticket A are read by the machine. If the entrance data on the station (a) are included in the read data on the ticket A, it may well be that the ticket A will be repetitively used for entrance/exit at only the station (a) and accordingly the wrong use frequency is written as +1. When the wrong use frequency of the ticket A reaches a prescribed level, e.g. five times, the owner data (personal name) on the read ticket A are sent to other stations via a communication control part. Thus, the sent owner data can be collated with the owner data on the commutation ticket that is repetitively used for entrance/exit at another station.

Filed: 1984-12-13
Abstract: PURPOSE:To reduce the cost of equipments by providing a moving electron beam generating part outside a welding chamber and by arranging the moving base of the body to be welded inside the welding chamber. CONSTITUTION:An electron beam generating device 2c and moving base 10 are arranged outside a welding chamber 9 and made movable with keeping the welding chamber 9 in vacuum by the evacuation device 5 of the inside of the welding chamber 9. The moving base 11 to move the body 1 to be welded is also arranged inside the welding chamber 9. The electron beam generating part 2c is made to have the moving quantity of each 1/2l2 against the center of the chamber 9 and the moving quantity l3 of the moving base 11 is equalized to the l2. The values of these l2, l3 are taken as the half of the length l1 of the body to be welded. It therefore becomes sufficient to make the length of the welding chamber (l1+l3). Namely the length of chamber 9 will do at about 1.5 times of the length of the body 1 to be welded. The equipments of welding chamber 9, evacuation device 5,etc. become smaller as well with this method and the equipment cost is reduced.

IPC: G01J1/44
Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To equalize the photometric time when it is limited even if the number for dividing a sensor is increased. SOLUTION: After the output from a sensor cell 1 is subjected to logarithmic compression, a normal photometric mode for delivering the output V as it is or an integrated photometric mode for delivering the output V after integrating through an integrating circuit 105 is taken selectively. Since an integrated output can be read out slowly after strobe flashing, the photometric time can be equalized even if the number for dividing a sensor is increased.

Title: Method and device for transmitting light and light transmission system
Inventor: NISHIMOTO HIROSHI
IPC: H04B10/516
Filed: 1995-10-09
Abstract: PURPOSE: To attain long distance transmission even in an optical fiber transmission line with large spectrum spread by moving a central wavelength of a rise part of an optical pulse to a long wavelength side and moving the central wavelength of the fall part to a short wavelength side. CONSTITUTION: This device is provided with an optical waveguide 1 largely applying phase modulation, the optical waveguide 2 small applying the phase modulation and a modulating electrode 3, etc. Then, phases of respective waveguides of a modulator are modulated asymmetrically. That is, the central wavelength of output light is moved to the long wavelength side at the rise part, and further, it is moved to the short wavelength side at the fall part. By wavelength chirping generated by asymmetrically modulating the phase and the effect of the positive spectrum spread of the optical fiber transmission line, since the wavelength becomes long at the rise part of the optical pulse, a propagation speed is delayed relatively, and the propagation speed is quickened relatively at the fall part conversely.  Thus, pulse compression occurs in the optical pulse, and a transmittable optical fiber length is improved as a result.
