摘要:
A liquid crystal antidazzle mirror for supplying a power to liquid crystal drive control circuit when a key plate is inserted into a key cylinder which comprises a key position detecting switch for detecting that the key plate is inserted into the key cylinder, and an initializing circuit for initializing the liquid crystal drive control circuit to either special mode of predetermined antidazzle or dazzle state upon receiving a detection signal of the key position detecting switch. Thus, the antidazzle mirror can automatically initialize the antidazzle mirror to either special mode of a predetermined antidazzle and dazzle states when power is supplied from a battery.

A photographic element having a photographic layer such as silver halide emulsion layer, protective layer, intermediate layer, subcoat layer, diffusion transfer image-receiving layer, antihalation layer and backing layer, can be improved in the adhesion between the layer and support, little curling on drying, and flexibility of the layer, by incorporating into the photographic layer a conversion mixture of a polyvinyl alcohol having a saponification degree of 96% or more and an ethylene-maleic anhydride copolymer.
摘要:
Printing characteristics of a lithographic printing plate material using the silver complex diffusion transfer process are markedly improved by including in layer which contains nuclei for physical development or a layer adjacent thereto at least one member selected from the group consisting of polyfunctional synthetic polymers containing a functional group having an affinity to said nuclei and a functional group providing hydrophilic property and developing agents for silver halide.
摘要:
A photographic binder prepared by heating a mixed aqueous solution of styrene-maleic anhydride copolymer, isobutylene-maleic anhydride copolymer and polyvinyl alcohol in acidic state makes it possible to coat a photographic coating liquid for forming photographic layers in the same manner as in the case of using gelatin and furthermore gives excellent physical properties to the resultant photographic layers.
摘要:
A reverse rotation preventing mechanism for synchronous motors includes a stopper interposed between a frame of a synchronous motor and a suitable stationary member, the stopper, including a stopping portion having elasticity and a rotating member fixed to a rotor shaft of the synchronous motor, and the rotating member, including a metallic flywheel and a gear disposed on the central portion of the flywheel, the flywheel having an engagement portion. The engagement portion of the flywheel of the rotating member is engaged with the stopping portion of the stopper when the synchronous motor is rotated in the direction opposite to a predetermined direction.

Disclosed are a developer for silver complex diffusion transfer process which contains a nitrogen-containing heterocyclic compound having a mercapto or thione group and, as substituent, an alkyl group of 4 or more carbon atoms, an aryl group, or a group having both the alkyl and aryl groups and further contains an alkali-soluble iodide in an amount such that the molar ratio of the iodide in terms of iodine to the heterocyclic compound is in the range of from 1:5 to 5:1 and a silver complex diffusion transfer process using said developer, according to which transferred silver images of improved color tone, maximum density, contrast and sharpness can be obtained.
摘要:
A processing solution composition for treating an image receiving layer in silver complex diffusion transfer process, which contains 1.7.times.10.sup.-3 to 1.7.times.10.sup.-2 mole/liter of a bromide and 2.0 to 12.0 mole-% of potassium ion based on total cations of the salts contained in the composition accelerates the transfer speed and gives a silver image high in maximum density, contrast and sharpness to the image.

摘要:
This invention relates to a rotation sensor which detects the magnetic field which changes with the rotation of a rotary shaft, thereby to detect the amount of rotation of the rotary shaft. The rotation sensor of the present invention has the boundaries between magnetized regions set with high precision. The boundaries forms magnetic fields stably, whereby the detection of rotation is performed with high accuracy.
摘要:
An electromagnetic solenoid drive apparatus for use in a vehicle for turning on an electromagnetic solenoid from a battery every time when a command switch is turned on comprises first and second resistors connected in series to each other on an electric line for flowing an electric current through the electromagnetic solenoid; a first switching element turned on in a state in which an output voltage of the battery is lower than a predetermined threshold voltage and short-circuiting both ends of the first resistor; a timer circuit operated for only a constant time in association with the turning-on operation of the command switch; and a second switching element turned on during only the operating period of the timer circuit and short-circuiting both ends of the second resistor.
