Title: Zoom lens
Inventor: TANAKA KAZUO
IPC: G02B15/16
Filed: 1985-07-25
Abstract: PURPOSE:To make the whole lens system having a high variable power and a large aperture ratio small in size by fixing the first and the third lens groups, executing a variable power by moving the second lens group, and executing a correction of an image surface variation caused by the variable power, and focusing by the fourth lens group. CONSTITUTION:The titled lens is constituted of the first lens group I of a positive refractive power, the second lens group II of a negative refractive power, the third lens group III of a positive refractive power, and the fourth lens group IV of a positive refractive power. A variable power is executed by moving the second and the fourth lens groups II, IV in the direction as indicated with an arrow. In these lenses, the second lens group II executes mainly the variable power, and the fourth group IV corrects an image surface variation caused by the variable power. Also, by moving the fourth lens group IV, focusing is executed. The first and the third lens group I, III are fixed in case of variable power and focusing. In case of focusing, by moving the fourth lens group IV being a part of a variable power system instead of the first lens group I, the number of movable lens groups is decreased and the mechanism is simplified, and the whole lens system is made small in size.

Title: Updating method for set data on coin discriminator
Inventor: NIITSUMA NOBUYUKI
IPC: G07D7/182
Filed: 1989-06-27
Abstract: PURPOSE:To know an update history of data even though the set data is updated by keeping the set data to updated for each update of set data in a storage means as a history. CONSTITUTION:The set data (old data DO, etc.) which is updated every time the set data is updated (update of storage area pointer MP, etc.) is kept in a storage means as a history. Therefore the data set newly is stored as the additional one for each update of the set data without destroying the set data so far stored. As a result, the update history of the set data is kept in a storage area of a coin discriminator. Thus the check of the factor for change of performance, the study for improvement of performance, etc., can be facilitated for the coin discriminator with read of the storage contents since the update history of the set data is maintained.

Filed: 1983-09-10
Abstract: PURPOSE:To increase the formation speed of a film and to form a thin film of any raw material by manufacturing fine particles and depositing fine particles on a substrate at independent stages respectively. CONSTITUTION:Fine particles 7 for film formation are manufactured independently. In this case, vapor-phase reaction is unnecessary, so any raw material is made into fine particles 7. The fine particles 7 of this film raw material are fallen from the upper part of an electric furnace 3 together with a carrier gas for uniform sedimentation. When the objective substrate 6 is preheated, the fallen fine particles 7 are deposited closely to form a good film. The substrate 6 is taken out so as to make the deposited film into glass, and heated above the fusion point of the raw material, obtaining the light guide film. When a film as a cladding is further formed, fine particles 7 containing a component having a low refractive index as a fine particle raw material are deposited and made into glass to obtain a film of multilayered structure.

Filed: 1979-12-20
Abstract: PURPOSE: To stabilize the linearity of the drive of a steering-wheel driving system vehicle by coupling knuckles, rotating by liquid cylinders operating with a command signal from a sensor sensing the traveling direction of the vehicle, with wheels.  
     CONSTITUTION: Vehicle body 1 is fitted with freely movable bracket 12 and sensor 3 sensing the traveling direction of the vehicle is fitted to it. Liquid cylinder 14 operating with a command signal for the traveling direction from sensor 3 is fitted to vehicle body 1 and a knucle rotating in the horizontal direction by cylinder 14 is coupled with wheel 2. Knucle 13 is coupled with bracket 12 via link 15, lever 16, arm 18, and link 19. As the vehicle runs beyond a prescribed range, sensor 3 senses that to send a command of correcting the traveling direction, and consequently cylinder 14 is put into operation to rotate knucle 13, thereby steering vehicle 2 in the correct direction. Since sensor 3 nears sensor line 5 earlier than the vehicle body, the steering amplitude of the drive is small and applying this to an automatic continuous forming machine for a concrete structure secures the linearity of the structure stably.
