Title: Automatic developing device
Inventor: SUGANO TAKAFUMI
IPC: G02B27/28
Filed: 1982-01-14
Abstract: PURPOSE:To automatically control a developing time, by monitoring a developing state with high accuracy by use of 2 luminous fluxes having each orthogonal plane of polarization. CONSTITUTION:Luminous flux from a laser 1 is irradiated to an original board 3. When development advances, the original board 3 is regarded as a diffraction grating, and transmitted light is divided into ''0''-order and + or - primary diffracted light I0, + or -I1. Each diffracted light is led into photoelectric converting elements 7, 8 by a concentric fiber 6, is amplified by amplifying circuits 9, 10, and after that, is led to an operating circuit 11, and when I1/I0 becomes some value, a development end signal is generated. As for this device, 2 sets are used, planes of polarization of each laser are made orthogonal to each other, and light of a desired diffraction order number is detected. By use of light of each plane of polarization, 2 kinds of developing states are detected, development is executed with high density from start of development till the first developing state, the development is executed with low density from the first developing state till the second developing state and the development is stopped in the second developing state.

Inventor: KOBAYASHI MASAHIRO
IPC: C08F8/30
Filed: 1980-01-17
Abstract: PURPOSE: To maintain stably the titled aq. polymer soln. over a long period of time without causing gelation, by incorporating a water-soluble polymer contg. carboxylate group into an aq. soln. of an acrylic acid hydrazide polymer.  
     CONSTITUTION: For example, an aq. NaOH soln. in an amount approximately equal to that of amido groups to be hydrolyzed, is added to an acrylamide polymer. A reaction is conducted at 50W100°C for 10minW3hr to form a partial hydrolyzate of the polyacrylamide (a water-soluble polymer), said partial hydrolyzate having an average MW of 100,000W400,000 and containing 5W50mol% carboxylate groups (e.g. sodium carboxylate group or ammonium carboxylate group). Then the water- soluble polymer is blended with an aq. soln. (having an intrinsic viscosity of 0.4W 28 at 25°C) of an acrylic acid hydrazide polymer in a ratio of 0.25W5mol of the carboxylate group in the water-soluble polymer per mol of the hydrazide group.

Abstract: PURPOSE:To prevent fluid from flowing out, thereby maintain high performance for a long time by providing a film the contact angle of which formed in 5min after fluid used for producing dynamic pressure has been dripped is equal to or more than 10 deg. for the end section of a micro gap wherein fluid exists to be used for producing dynamic pressure. CONSTITUTION:In a dynamic pressure fluid bearing composed of a shaft 2 including a housing 1 and a hallingbone groove 5, and a thrust bearing 3, silicon oil is used as fluid for producing dynamic pressure so that the end section of the micro gap of a section producing dynamic pressure is coated with fluid wherein poly fluoro ether containing isocyanate group is uniformly dispersed into high fluoride organic solvent such as flon R113. After coating has been over, solvent is evaporated so as to obtain a film 4. The contact angle of silicon oil is about 50 deg. against the face of the film 4, the provision of the film 4 enables the duration of current bearing function to be increased by a factor of about 4.

Title: Fault-position decision circuit for coaxial transmission line
Inventor: HASEGAWA HIKARI
IPC: G01R31/08
Filed: 1979-01-20
Abstract: PURPOSE:To automatize the detection and indication of a fault position. CONSTITUTION:Once a fault occurs on a transmission line and supervisory line 2 forms a short circuit of shorting element 1, the external gain of operational amplifier 3 is determined by a supervisory-line loop resistance and a DC output corresponding to it appears at output terminal 4 of the operational amplifier. This DC output varies in constant steps according to a change in the fault occurrence point of supervisory line 2. This DC output is A/D-converted and further coded by decoder 6 into a n-scale code, which is extracted as the n-number outputs. Those outputs connect to light emitting diodes displaying fault positions, and a fault occurrence point is indicated by letting a light emitting diode, which corresponds to the point, come on.

Title: Image pickup device
Inventor: MIYAGAWA YASUMI
IPC: H04N5/335
Filed: 1989-01-11
Abstract: PURPOSE:To pick up an object moving at a high speed by making each transfer electrode of a vertical transfer register equal with a driving means in before and after prescribed period when a signal charged is read from a photodetector prior to a high speed shutter operation. CONSTITUTION:A signal equivalent to a vertical smear component extracted by a vertical transfer register 12 of a frame interline type FIT-CCD 20 is stored in a memory 23 in advance in the operation of an electronic shutter while the charge distribution is averaged. Then a driving pulse to make the electronic shutter operation to the FIT-CCD 20 is given. A vertical smear component stored in the memory 23 is reduced from the signal in this case. Thus, an excellent video signal is obtained and an object, e.g. moving at a high speed is image- picked up sharply. Moreover, since the vertical smear component is reduced, the incident luminous quantity is increased, thereby quickening the shutter speed.

Abstract: PURPOSE: To constitute an induction detector, which detects the passing of a suttle, so that the motion of the shuttle is not hindered. CONSTITUTION: The detector 3 is arranged on the flank of a holder 1 which supports a metallic guide 2 disposed along a shuttle path 20. The detector 3 has a coil arranged as closely as possible to one axis of the guide 2. Further, a permanent magnet is provided in order to magnetize the adjacent guide.
