Title: Image recorder
Inventor: IMAI MASAAKI
IPC: G03B27/32
Filed: 1991-02-22
Abstract: PURPOSE:To provide such an image recorder that is able to improve the extent of image quality even in an image peripheral part where a quantity of light is insufficient. CONSTITUTION:A liquid-crystal light valve panel (LCD) 7 and microcapsule paper 10 are set up in the lower part of a tungsten halogen lamp 3. In addition, first of all, this microcapsule paper 10 is exposed to light over the whole surface via the LCD then a picture element in a center part of the LCD 7 is closed, displaying a peripheral part alone on an image, and thereby exposure is performed again. In addition, more picture elements than the last time are closed, and images at the peripheral part alone are displayed, thus the third time exposure is performed. Doing like this, the central part of the image is exposed one time, the peripheral part nearer to the central part is exposed two times and the peripheral part nearer to the outer circumference is exposed three times, respectively, through which such exposure that is no drop in peripheral luminous energy can be done in this way.

Title: Proximity sensor
Inventor: OGATA AKIMITSU
IPC: H03K17/95
Filed: 1993-02-18
Abstract: PURPOSE:To obtain a proximity sensor which is hardly affected by temperature variation and stably operates by eliminating variance in detection sensitivity among bodies. CONSTITUTION:A 2nd resonance circuit 5 which has a detection coil 6 for body detection resonates with the oscillation signal of an oscillation circuit 1 which is supplied through a 1st impedance element R17. When a body approaches the detection coil 6, characteristics (Q) of the 2nd resonance circuit 5 vary and then the resonance amplitude level of the 2nd resonance circuit 5 varies. This variation is detected to detect the approaching body. Thus, the 1st impedance element R17 is arranged between the oscillation circuit 1 and 2nd resonance circuit 5 and the oscillation circuit 1 is hardly affected by the variation in the characteristics (Q) of the 2nd resonance circuit 5 due to the body approach, so the detection sensitivity is stabilized.

Filed: 1984-02-17
Abstract: PURPOSE:To readily form a pole for detecting a frequency by magnetizing the strong and weak N- and S-poles at a fine equal pitch on the outer periphery of a rotor to provide poles for detecting the frequency. CONSTITUTION:4-pole circular field magnet 9 alternately magnetized radially at N- and S-poles is secured to the inner surface of a body 2 opposed planely to an armature 6.

Title: Manufacture of silver halide photographic emulsion
Inventor: MORI TOMOO
IPC: G03C1/34
Filed: 1995-02-17
Abstract: PURPOSE: To reduce fog and to obtain high-contrast photographic characteristics and to enhance a covering power by incorporating a low molecular gelatin in a specified average molecular weight range and at least one of tetrazaindene or its derivatives. CONSTITUTION: The silver halide emulsion grains use the low molecular gelatin in an average molecular weight of 5,000-70,000, preferably, 10,000-50,000, especially, 10,000-30,000, as a protective colloid, and they contain at least one of the tetrazaindene and its derivatives. If the average molecular weight of the gelatin is lower than 5000, the viscosity of the emulsion is too low, resulting in unsuitably fast settling of the silver halide grains. It is preferred that the tetrazainde compound is added in a stage before a desalting step.

Filed: 1992-01-22
Abstract: PURPOSE:To easily discriminate the reception method of a received picture at a reception side by inserting an identification mark representing the transmission method in a picture and sending the resulting picture in the case of picture transmission by various transmission methods. CONSTITUTION:In the case of picture transmission by self-transfer, polling transmission or relay transmission, the facsimile equipment reads a mark registered corresponding to each processing (step 401). Then, the read mark is inserted to a picture and sent to a destination (402). Suppose that a picture in figure, for example, is a picture sent by the relay transmission, TTI information (a) is information inserted at a sender of an original picture and a mark (b) is information inserted by the facsimile equipment. The picture is sent to the relay transmission destination. Thus, the operator of the receiver side discriminates the reception method by having only to observe the received picture at a glance.
