Title: Exposing mechanism for electrophotographic printer
Inventor: KIKUCHI TORU
IPC: G03G15/047
Filed: 1989-04-22
Abstract: PURPOSE:To form a latent image with light beams of a small output and a small diameter by providing a first light emitter performing pre-exposure and a second light emitter forming a latent image. CONSTITUTION:The light emitter 2 emits light 6 of stable brightness that does not attract toner, and a polygon motor 1 scans the image forming plane of a photosensitive drum 3 with the light 6 to perform pre-exposure. Then, the modulated light emitter 4 alters the brightness with the aid of a picture signal to emit light. The pre-exposed image forming plane is scanned with the light 5 to form a latent image on the photosensitive drum 3. Since the modulated light emitter 4 raise a dot density, it lowers output and makes the diameter of the light beam smaller. Therefore, the modulated light 5 alone cannot raise the potential of the photosensitive drum 3 to the degree that toner is attracted. However, if the plane pre-exposed by the light 6 with stable brightness is irradiated with the light 5, the toner is attracted. Consequently, a latent image of a potential that can attract the toner can be formed.

Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To surely perform status reception judgement without using a status control circuit and to instruct retrial by connecting a status reception judgement circuit for originating the instruction of a retrial processing to a CPU when retrial signals received from a bus are in an assertion state. SOLUTION: The status control circuit is not used and the retrial signals from bus BUS 2 are outputted as they are as retrial instruction signals in the status reception judgement circuits SRJ1 and SRJ2. That is, when the retrial signals received from the bus BUS 2 are in the assertion state, since they are outputted as they are, the retrial signals are outputted. When the retrial signals are in a negation state, the decoding state of a status is reflected, and since the identification output of the status code 0001 of a decoder 1 becomes '1' when the status is normal, an AND gate 3 is turned to '1' and the judgement output of reception possibility is performed. In this case, at the time of status abnormality, the output of the AND gate 4 is turned to '1' for indicating error judgement.

Title: Shower-faucet changeover valve
Inventor: KIDOUCHI YASUO
IPC: F16K11/044
Filed: 1986-05-06
Abstract: PURPOSE:To prevent vibrating changeover operation by absorbing the water hummer function in a flow-out path of shower by means of a piston even when the changeover operation is performed abruptly. CONSTITUTION:The flow-in pressure of hot water is cancelled between a faucet side valve body 13 and a shower side valve body 15 by equalizing the pressure receiving areas of said valves 13, 15 so as to protect a changeover valve 17 from the influence of the flow-in pressure. When the pressure loss of such as a shower head 11 is high and abrupt in the shower side flow-out path 12, the water hummer occurring in the shower side flow-out path 12 is absorbed by means of a piston 19 against a shower side valve body 15. Occurrence of vibrating changeover can be prevented by functioning the pressure in a faucet side flow-out path 10 onto the changeover valve 17 when the water is delivered from the faucet while reducing the pressure receiving area of the piston 19 slightly when compared with that of the shower side valve body 15 when the water is delivered from the shower.

Title: Electrode plate for color displaying device
Inventor: FUKUYOSHI KENZO
IPC: G09F9/30
Filed: 1985-05-15
Abstract: PURPOSE:To prevent the reduction of the liquid crystal life due to ion pollution and to improve the chemical resistance and the reliability by positioning the color filter layer between the transparent substrate and the ion preventing layer and laminating a metallic thin film pattern and a transparent electrode to overlap a part on the ion preventing layer. CONSTITUTION:After a color filter (CF) is formed, a transparent electrode 22 is formed so as to overlap onto a CF and to a part of the terminal part. The transparent electrode 22 can be directly formed on the CF, and when the dot pitch comes to be the fine pitch of 300mum or below, the electrode is smoothed by an overcoating pattern 27 on the CF once. By the overcoating, the displaying unevenness and the life reduction of the liquid crystal can be prevented. Usually, since the CF is patterned for respective colors by the dyeing method and the printing method, the difference of 0.5-2mum occurs in the dyeing method, and the unevenness of about maximum 5mum occurs in the printing, and therefore, to laminate the transparent electrode such as ITO, the overcoating layer of about 0.2-2mum is provided, the surface is smoothed, thereby, the variance of the resistance value of the transparent electrode comes to be less and the advantageous liquid crystal driving can be obtained.
