Title: Zoom finder
Inventor: OZAWA TOSHIRO
IPC: G03G13/02
Filed: 1988-01-14
Abstract: PURPOSE:To reduce the number of constituting lenses and to satisfactorily correct aberrations of an external image and a frame image by forming at least both faces of a negative lens in a third lens group to aspherical surfaces and setting the focal length of a i-th lens group, the focal length of a positive lens in the third lens group, and the zoom ratio to satisfy specific conditions. CONSTITUTION:At least both faces of a negative lens L3 in the third lens group out of four lenses are formed to aspherical surfaces, and a focal length f1 of the i-th lens group, a focal length f4 of a positive lens L4 in the third lens group, and a zoom ratio (k) satisfy conditions of inequalities I. The zoom ratio (k) is equal to (the finder magnification in the telephoto end)/(the finder magnification in the wide angle end). Thus, aberrations re satisfactorily corrected although the number of constituting lenses is small and this zoom finder is realized at a low cost.

Title: Hardening device for rack bar
Inventor: OOKAWA YOSHIHIRO
IPC: C21D1/09
Filed: 1981-01-20
Abstract: PURPOSE:To permit uniform hardening of tooth parts of a rack bar in hardening the rack bar through direct conduction of high frequency electric conduction by making the opposite areas of both end parts of adjacent conductors disposed to the tooth parts of the rack bar larger than other parts. CONSTITUTION:Chips 12, 13 made of steel plates are joined respectively to the right end of the front face and the left end of the rear face of adjacent conductors 6 in such a way as to connect electrically to the conductors 6, and the top surfaces thereof are positioned near the part A and part B of a rack bar 8. The chips 12, 13 enlarge partially the areas in the upper part of both end parts of the conductors 6, thereby improving proximity effect. Thereby, uniform hardening is accomplished in spite of the case in which the angle theta of the teeth in the tooth parts 9 of the rack bar 8 is >=6 deg.. If metallic plates 14, 15 of magnetic material are superposed respectively on the outer side faces of the chips 12, 13, the magnetic flux density in the parts A, B are increased, and the quench- hardened layers of the parts A, B are deepened.

Title: Communications network fault processing system
Inventor: YOKOYAMA TARO
IPC: H04M3/00
Filed: 1986-01-16
Abstract: PURPOSE:To improve the reliability of a signal transmission path, to lighten a control load and to shorten the signal transfer time by transmitting a signal, which is received through one signal transmission path, through a connector and the other signal transmission path by controlling only the other controller. CONSTITUTION:A connection line 6 is installed between plural connectors 8010 and 8011. If a channel Y0 contained by the connector 8010 fails to transmit a signal, a channel Y1 which is connected to the connector 8011 and is outgoing to the same destination as the channel Y1 is checked transmittable. Then a channel X0 contained by the connector 8010 is connected to a communications controller 8021-3 through the connection line 6, and a signal coming from the channel X0 contained by the connector 8010 is transmitted to the channel Y1 contained by the connector 8011 under the processing of a controller 8031. Accordingly the installation of a standby channel is unnecessary. Besides, the reliability of a signal transmission path can be maintained without increasing communications loads between controllers.

Filed: 1978-01-24
Abstract: PURPOSE: To make reproduction without using any additional optical system and the like by a novel focusing method by providing an information protecting layer on a signal disc carrier.  
     CONSTITUTION: A protecting layer 22 is provided on a signal disc carrier 21 and signal read light 23 is entered. In order to maintain the distance between a condensing lens 24 and the signal face constant, a focus error signal is detected with a photo detector 27 and by the correction servo signal thus obtained, the focusing lens 24 is electromagnetically driven in the optical axis direction, whereby the focus error is corrected. The phase difference corresponding to the focus error is converted to an error voltage by a phase comparator 33. To this end, the output of a photo detector 26 is high-frequency amplified 29 and is limited to a fixed amplitude with a limiter 32, after which it is applied to a phase comparator 33. On the other hand, the output of the photo detector 27 is amplified 28 and is subjected to phase shifting 30 by a fixed quantity, after which it is applied to the other input terminal of the comparator 33, thence the voltage proportional to the phase difference is drawin out by an LPF 34.

Title: Cylinder number controlling engine
Inventor: FUJIMOTO MISAO
IPC: F02D13/06
Filed: 1984-01-18
Abstract: PURPOSE:To reduce vibration caused by variation in engine torque by adjusting the timing or the amount of lift of an intake valve so that the combustion pressure of operating cylinders is reduced when operating an engine with the number of cylinders reduced. CONSTITUTION:At the time of idling in an area, in which the number of cylinders is reduced, the closing timing of an intake valve is made delay later than the base timing, a slight blow-back of air occurs, charging efficiency is reduced, and combustion pressure is reduced, in a first and a second cylinder which continue to operate, causing variation in torque to be less, and the vibration of engine to be reduced. The closing timing of the intake valve may be made delay not only at the time of idling but also in the whole area at the time of operation with reduced cylinders. It is also possible to reduce vibration by advancing the closing timing of the intake valve earlier than the base timing, and increasing the amount of overlapping. A similar end can also be achieved by reducing the amount of lift of the intake valve.

Abstract: PURPOSE:To obtain an artificial leathery formed laminate capable of bending from a laminated sheet having an artificial leathery uneven pattern in which an oriented film is laminated to base fabric without breaking or deteriorating the oriented film without eliminating the artificial leathery uneven pattern and discoloring and fading of a color tone and a method for forming the laminate. CONSTITUTION:An oriented plastic film (A), a cushioning layer (B) and base fabric (C) are laminated in the order of (A)/(B)/(C) and a tension applied to the oriented plastic film (A) in bending is absorbed by the aforementioned cushioning layer (B). Thereby, its toughness is kept and breaking is prevented from occurring. Furthermore, the oriented plastic film (A) is laminated through the base fabric (C) and the cushioning layer (B) to provide a laminated sheet. The resultant laminated sheet is then heated at a lower temperature than the melting point of the above-mentioned oriented plastic film (A) by >=50 deg.C to carry out bending. As a result, the tension applied to the oriented plastic film (A) in bending is absorbed and relaxed with the aforementioned cushioning layer (B) and the oriented plastic film (A) is simultaneously prevented from breaking or deteriorating. The above-mentioned artificial leathery uneven pattern is prevented from being eliminated and a color tone is prevented from discoloring and fading.
