Title: Discharge device for image forming device
Inventor: TSUJITA MITSUSHI
IPC: G03G21/08
Filed: 1995-01-11
Abstract: PURPOSE: To effectively prevent the charge characteristic or the sensitivity of a photoreceptor from being deteriorated, to realize an excellent image forming and to make an image forming device compact by setting the light quantity distribution of a discharge light irradiation part to be such distribution that the light more than the half of total discharge light quantity is emitted toward the half part on an upstream side of the perpendicular at the center of a discharge light source. CONSTITUTION: For example, the discharge light source 2 is provided so as to be inclined to the photoreceptor 1. Then, the light quantity distribution A at the discharge light irradiation part of the surface of the photoreceptor 1 is set so that the light quantity more than 50% of the total discharge light quantity is emitted on the upperstream side of the central part of the light source 2. Therefore, the length of the bottom of the light distribution curve toward a main charger 3 becomes short. So that photoreceptor 1 is hardly affected by flare light and the charge property or the sensitivity is effectively prevented from being deteriorated. Therefore, the light source 2 and the charger 3 can be arranged as near as possible, which serves extremely advantageously for making the image forming device compact.

Title: Production of aqueous resin dispersion
Inventor: OTSUKA MASAHIKO
IPC: C08F290/06
Filed: 1995-01-11
Abstract: PURPOSE: To obtain an aqueous resin dispersion which does not change in adhesion after storage and having a film Tg in a specified range by emulsion- polymerizing a (meth)acrylic-acid-containing radical polymerizable monomer in the presence of an epoxy resin in an aqueous medium having a pH in a specified range. CONSTITUTION: A (meth)acrylic-acid-containing radical-polymerizable monomer is polymerized in an amount of 40-80 pts.wt. in the presence of 20-60 pts.wt. epoxy resin in an aqueous medium. In this emulsion polymerization, the pH of the aqueous medium is adjusted to 5-8 to obtain an aqueous resin dispersion which can give a film of a Tg of 10-40 deg.C. As the pH during the emulsion polymerization is adjusted to 5-8, this dispersion does not undergo any change during storage, does not undergo any change in adhesion after storage, has good compatibility as compared with a conventional emulsion being a combination with an epoxy resin, has therefore good contact, can be smoothly cured with an epoxy resin and has therefore performance equivalent to that of a solvent-based chloroprene adhesive.

Title: Memory back-up circuit
Inventor: MORI TAIJI
IPC: G06F12/16
Filed: 1989-01-11
Abstract: PURPOSE:To detect the abnormal drop of the back-up voltage even after the recovery of the voltage by turning off a switching circuit when the back-up voltage drops less than the minimum working voltage level and keeping the output level of a comparator set when the switching circuit is turned off until this circuit is turned on again even though the back-up voltage is recovered. CONSTITUTION:When the power voltage drops and the output of a constant voltage circuit1 is turned off, the back-up voltage Vb is supplied to a memory 2 via a capacitor 3. Then the voltage Vb drops down to a level Vboff after the transistors TR 4 and 5 are turned off. Thus the output of a differential amplifier 6 is kept at +Vb since both TR 4 and 5 are kept off even after the Vb is recovered. The output of the amplifier 6 shows continuously a fact that the voltage Vb dropped extraordinarily at least at a certain time point until the input of a start signal S. Thus it is possible to secure a function to prove the extraordinary drop of the voltage Vb.

Abstract: PURPOSE:To discharge the charge stored in the wiring capacity to reduce the readout time, by providing the constant current circuit with the output gate of PLA (Programmable Logic Array). CONSTITUTION:Between the output wiring l from the OR logic matrix array OR of the output buffer circuit BUF to the output gate OG and the ground GND, the constant current circuit consisting of the npn transistor Trb is connected in series with the discharge resistor R1. Since the time when the output of the array OR changes from H to L is the time to discharge the wiring capacitor C with the constant current i, the readout time can be reduced by several tens of % with suitable set of the current i.

Title: Semiconductor memory device and its manufacture
Inventor: SUGAYA SHINJI
IPC: H01L21/8247
Filed: 1988-01-08
Abstract: PURPOSE:To decrease the step-difference of a memory cell, and reduce the disconnection and short-circuit of a wiring, by forming the element isolation band of a memory cell composed of a field effect transistor, by using only a channel stopper layer. CONSTITUTION:An field insulating film is not provided, however, a channel stopper later 20 only is employed as an element isolation belt, whose depth is made large in order to prevent the generation of punch through between cells. For example, the depth of the P<+> type channel stopper layer 20 is made about 4000Angstrom , which is 1000-2000Angstrom  deeper than the conventional case where a field insulating film is installed. When boron fluoride (BF2) ion is used instead of boron ion in the ion implantation process to form the P<+> type channel stopper layer 20, accelerated oxidation progresses at the time of heat treatment, so that the installing of a comparatively thick insulating film 19 on the channel stopper layer 20 is enabled. Thereby the step-difference of a memory cell is reduced, and the disconnection of a wiring is prevented.

Abstract: PURPOSE:To prevent accident due to erroneous insertion of a PROM by storing specification data consisting of a mounting position to which the PROM is to be inserted originally or number indicating itself etc. in a memory area of specified same relative address in each PROM. CONSTITUTION:When the head PROM of correct number is inserted in a mounting position L1 to which a head address AD is allotted PROM to be mounted, and another PROM of erroneous number is inserted in the next mounting position L2, input/output signals etc. are initialized in the step S1 after making power source. Specification data in above-mentioned specification data address of other PROM mounted in the mounting position L2 are read out in the step S2, and discriminated whether the data are specification data corresponding to the mounting position L2. As it is no in this example, an alarm is outputted in the step S6 to inform that erroneous insertion is made. In the case where other PROM of incorrect number is inserted in the first mounting position L1, after making initializing of the step S1 after supplying power source, an alarm is outputted in the step 6 via a passage shown by a dotted line.
