Title: Optical system for reading scale on theodolite
Inventor: ISHIKAWA YUZURU
IPC: G02B27/32
Filed: 1979-12-27
Abstract: PURPOSE: To reduce the number of lenses in a manner to identify the performances on an altitude angle scale and a horizontal angle scale with each other and to facilitate handling thereof, by a method wherein a right-angled prism and a semitransmission prism for light coupling are inserted into a light path of a theodolite.  
     CONSTITUTION: Surfaces 7a and 7b of a right-angled prism 7, which cross each other at right angles, are formed into a mirror surface. An illuminating light incident on the surface 7a reflects upward, and comes into an object 4 after it is reflected by a semitransmission surface 8a of a semitransmission prism passing through a scale 1a on an altitude angle scale disc 1 through the medium of a right-angled prism 9. In the meantime, a light reflected by the surface 7b irradiates a scale 2a on a horizontal angle scale disc 2 through the medium of a prism 11, and enters into a prism through the medium of a right-angled prism 12. After the light is reflected twice by means of the surfaces 7b and 7a, it enters into the object 4 after passing through the semitransmission prism 8. A light going out of the object 4 is formed into an image on a focus disc 5, and its reading can be taken with the same field of vision. This allows the performances on the two scales to be identified with each other, and permits reduction in the number of lenses and facilitation of operation.

Title: Automatic ticket examination machine
Inventor: HARADA JIYUNICHIROU
IPC: G07B15/00
Filed: 1994-06-30
Abstract: PURPOSE:To provide a ticket examination machine of a non-contact card type, which can execute re-communication in a ticket examination path when the possessor of a valid card is errorneously judged to be a passenger without a card, by starting again the operation of a ticket examination processing when the transfer of data between a main body and the card continues for more than prescribed time while the passenger without the card is detected and the arithmetic function of the ticket examination processing is stopped. CONSTITUTION:When the card C is approximated to a communication area, the transfer of data between the main body and the card C is started, CPU 11 executes the operation for ticket examination and the arithmetic processing is stopped when the passenger is judged to be one who does not possess the card. When the user possessing the valid card C cannot be examined owing to the bad condition of data transfer, the user usually brings the card C again into closer relationship with the communication area without leaving from the ticket examination path when a door 1a is closed. Thus, the arithmetic function of the ticket examination processing is resumed when the time of re-approach continues for prescribed time, three seconds, for example, or total reapproach time is more than three seconds.

Title: Induction heating device for slab
Inventor: SAKAMOTO HIDEO
IPC: H05B6/10
Filed: 1990-06-27
Abstract: PURPOSE:To prevent outflow of inert gas from an opening and eliminate drop of the temp. of the slab end by furnishing a motion device and a cover enclosing the opening, and supplying the inert gas to inside of this cover. CONSTITUTION:A cover 14 for gas seal is fixed to the oversurface of a furnace lid 4 in such a way as enclosing the whole motion device 10, and an opening 4a of this furnace lid 4 opens inside of the cover 14. An inert gas 15 such as nitrogen gas is supplied from a gas supply port 14a provided in the oversurface of the cover 14. Therefore, the pressure inside of the cover 14 becomes the same as the internal pressure of a furnace vessel 3 substantially. This eliminates outflow of the inert gas in the furnace vessel 3 to the outside from openings 6a, 4a, and there is no more occurrence of temp. dropping phenomenon at the top 2b of the slab material concerned 2. Thus consumption of the inert gas is decreased.

Title: Electrophotographic method
Inventor: TOMITA SATORU
IPC: B41J2/44
Filed: 1979-12-28
Abstract: PURPOSE:To prevent the toner from sticking on areas other than those corresponding to an original and from causing faults by exposing the areas other than the areas where the writing and picture information is formed on a uniformly charged recording body by means of a light beam in an electrophotographic method for obtaining an electrostatic latent image by scanning the light beam on said recording body. CONSTITUTION:A drumlike recording body 1 is uniformly charged by a charger 2. Next, the light beam L from a light source 5 scans an exposure area 4 by a scanning optical system 6. Thence, the toner is supplied and the image is developed by a developing device 3. If at the time of performing positive-positive recording in this manner only the area corresponding to the area of the width (l) of the original is scanned, the toner sticks on the parts 8 other than the area corresponding to the original, at both end parts of the recording body 1, and this gives adverse influence upon cleaning and other processes. In order to prevent this, even the parts 8 are scanned wider than the width (l) area by the light beam L along the scanning line S-S. In this way, common unit and process is employed for ordinary electrophotographic copiers.

IPC: F02B39/12
Filed: 1980-12-08
Abstract: PURPOSE: To improve the starting characteristic and the performance in a low speed range of an engine, by using a starter motor as an additional drive source for an engine driven supercharger, and by controlling engagement of a clutch coupled to a drive shaft in association with the drive condition of the engine.  
     CONSTITUTION: A stater motor 6 as an additional drive source is operated and therefore, a drive shaft 13 is rotated with an engine 6 being started, when a stater switch 7 is turned-on to close a magnet switch 9. An electro-magnetic clutch 14 is not yet energized and therefore a supercharger 4 does not operate, since a thermosensitive switch 16 is opened at a hogh temperature of the engine 1, but the switch 16 is closed when the temperature of the engine 1 is lowered, so that the supercharger is driven, thereby the starting characteristic is enhanced. Even if the magnet switch 9 is opened when the starter switch 7 is opened after the engine 1 is started, the starter motor 7 is energized through a free switch 20 which is closed by a core 19 moved back due to the energization of a magnet 17, so that the supercharger 4 continues to operate. The thermosensitive switch 16 is opened when the temperature of the engine 1 becomes high, thereby the starter motor 6 makes to a stop.

On the back surface, a drain electrode 13 is laid, and a plurality of electrodes 10, 11, 12 are connected 14, 15, 16. Since the basic unit wherein the first and second MOSFETs are cascade-connected connects side by side with depletion layers extended from each unit and form the equipotential surface parallel with the substrate surface resulting in no field concentration in a blocking state that a voltage is applied between a source drain, any means for imparting high withstand voltage for individual unit as in a lateral structure is unnecessitated, the channel width per unit area increases, accordingly they can be formed to high withstand voltage and usable for large current.
