Title: Comparator
Inventor: IKEDA MASAHARU
IPC: H03K3/02
Filed: 1984-07-13
Abstract: PURPOSE:To obtain a sufficiently stable hysteresis even at a low comparison level by connecting a constant current circuit to other input of a comparison amplifier circuit to one input of which a comparison input is applied and to other input of which a reference input is fed and applying on/off control to the constant current circut with an output of the comparison amplifier circuit. CONSTITUTION:When an input voltage to an inverting terminal of the comparison amplifier 11 is smaller than an input voltage to a non-inverting terminal, its output goes to H, a transistor (TR)16 is saturated and a rush current of a current source 15 is zeroed. When the input voltage at the inverting terminal is increased and slightly larger than the input voltage at the non-inverting terminal, an output of the amplifier 11 goes to L, the TR16 is turned off and the rush current of the current source 15 is I15. The hysteresis in this case dependes on R3, R4 and I15 only. Even if the comparison level is low, the sufficiently stable hysteresis is obtained.

Abstract: PROBLEM TO BE SOLVED: To prevent an absorption unevenness of an ink by rapidly absorbing a liquid-like ink and to prevent blurring or a reservoir of the ink by arranging a color material receptive layer containing inorganic fine particles, a mordant, a crosslinker of a water soluble resin, and a light resistance improving agent on a support. SOLUTION: A support is coated with a coating liquid containing inorganic fine particles and a water soluble resin. Simultaneously with the coating or before a coated layer exhibits a decreased dry rate, a solution containing a crosslinker capable of crosslinking the resin and a mordant is given. Then, a color material receptive layer is formed by curing, thereby constituting the recording sheet. A light resistance improving agent may be added to any of a coating liquid containing the fine particles and the water soluble resin and the solution containing the crosslinker capable of crosslinking the water soluble resin. As the crosslinker, a boron compound is suitably used, and as the fine particles, silica fine particles each having a mean primary particle size of 20 nm or below are suitably used.  As a preferred embodiment of the water soluble resin, a polyvinyl alcohol, a gelatin or the like is used.

IPC: G02B6/34
Filed: 1982-08-26
Abstract: PURPOSE:To allow one wavelength multiplex demultiplexer to perform demultiplexing covering plural wavelengths, and to reduce its size and cost, by sticking an amorphous semiconductor film to one end surface of a convergent rod lens which varies in refractive index radially from the center part almost with a square distribution. CONSTITUTION:The amorphous semiconductor 7 vapor-deposited on one end surface 6 of the convergent rod lens 5 varies in refractive index when irradiated with light having wavelength close to absorption edge, forming a diffraction grating 8 of interference fringes. An incident wave 10 having wavelengths lambda1, lambda2, and lambda3 enters the rod lens 5 from an end surface 9 through a fiber 11 and is reflected by the diffraction grating 8. Its angle of reflection is different depending upon the wavelengths, and the light is focused on different positions on the end surface 9, thereby demultiplexing light signals with the wavelengths lambda1, lambda2, and lambda3 from fibers 21, 31, and 41 couled with the positions.

Title: Printing head of printer
Inventor: YAMANAKA YASUYOSHI
IPC: B41J2/28
Filed: 1995-06-14
Abstract: PURPOSE: To suppress the wear of a contact surface between a yoke and an armature by embedding a water-resistant material with a higher coefficient of cubical expansion than that of a raw material for the yoke, almost flush with the contact surface, in a recessed part formed in the contact surface between the yoke and the armature. CONSTITUTION: A wear-resistant material 1C-1 is flush with the contact surface of a yoke 1 in the initial stage of a printing action. Consequently, an armature 2C hammers the surface of the wear-resistant material 1C in addition to the yoke 1. If the temperature of the yoke 1 increases, the wear-resistant material 1C-1 becomes larger than the contact surface of the yoke relatively as the wear-resistant material 1C-1 has a higher coefficient of cubical expansion than the raw material for the yoke 1. However, the effect of the void on the magnetic characteristics is insignificant so that no adverse effect on the printing quality exists. For this reason, only the surfaces of the armature 2C and the wear-resistant material 1C-1 are hammered and the wear-resistant material 1C-1 becomes worn out.  Besides, if the number of times of printing increases and the wear-resistant material 1C-1 also is worn out, the yoke 1 is also hammered along with the wear-resistant material 1C-1, and the surface pressure of the yoke 1 again becomes low, resulting in the simultaneous occurrence of wear in the yoke 1C-1.
