Title: Production of 6-chloropurine
Inventor: YOKOSHITA MASAHIKO
IPC: C07D473/40
Filed: 1981-09-07
Abstract: PURPOSE:Hypoxanthine and phosphorus oxychloride are heated in the presence of a tertiary amine at a specific temperature to produce 6-chloropurine used as an intermediate of purine derivatives in high yield. CONSTITUTION:On the reaction between hypoxanthine and phosphorus oxychloride in the presence of a tertiary amine such as N,N-dimethylaniline or alpha- picoline, the mixture of raw materials is rapidly heated over 130 deg.C in 10-15min or the temperature is kept at lower than 90 deg.C for 4hr to give the objective compound. Since phosphorus oxychloride acts as a solvent as well as a reagent, the amount is 10-20 times the molar quantity of hypoxanthine. The tertiary amine is 2-3 times the molar amount of hypoxanthine.

Title: Apparatus and method for tightening flange
Inventor: ABE RYOJI
IPC: F16B31/04
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a flange tightening device which can eliminate retightening work by preventing bolts and nuts for tightening a flange from loosening even if the temperature of high-temperature piping and the flange protrudingly- mounted on the end of the piping rise. SOLUTION: This flange tightening device 9 consists of a flange 1, a nut 3 sandwiching it from both outsides, a high-tension type washer 4 inserted between the flange 1 and the nut 3, and a bolt 2 passing through all of them integrally. The washer 4 is formed out of a material whose linear expansion coefficient is larger than that of the bolt 2 and the nut 3. Using the high-tension type washer 4, even if the flange 1 becomes hot and the bolt 2 gets longer due to heat, permits the high-tension type washer 4 to be heat-elongated more than it to pull the bolt 2, thus it is possible to prevent tightening from being loosened.

Title: Focus detector
Inventor: KONNO OSAMU
IPC: G02B7/28
Filed: 1990-05-31
Abstract: PURPOSE:To detect a focus state with high accuracy at all times even when dual reflection exists in an irradiated object by providing an optical active element in an optical path of a reflecting light form the lighted object made incident in a photodetector and varying an optical phase difference between two polarized components orthogonal to each other. CONSTITUTION:A longitudinal optical modulation element 31 is arrange in an optical path of a reflecting light from a recording medium 25 between a half prism 23 and a detection prism 26. The longitudinal optical modulation element 31 consists of an optical crystal 32 and a couple of transparent electrodes 33 orthogonal to an optical path having the optical crystal 32 inbetween. When a half wavelength voltage Vpi is applied from a DC power supply 35 to a couple of the transparent electrodes 33 via a switch 34 while turning on/off the switch 34 periodically, the longitudinal optical modulation element 31 acts like a 1/2 wavelength plate when the switch 34 is closed and acts like a mere transmission plate when the switch 34 is turned off. Thus, the luminous quantity of the luminous flux after the reflection of the detection prism 26 is made constant independently of the polarization of the incident luminous flux. Thus, even when retardation exists in a transparent protection layer 25A, stable focus detection is attained with high accuracy.

Title: Transfer paper separation mechanism
Inventor: MIZUTANI NAOKI
IPC: G03G15/16
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To provide a transfer paper separation mechanism capable of preventing the vicinity of the end part of an intermediate transfer belt from being damaged due to the voltage applied from a separation needle. SOLUTION: The separation needle 62' is formed so that the height (h') of its both end parts having prescribed width (w) is lower than the height (h) of its central part. Thus, a distance between the tip 62a of the needle 62' and the intermediate transfer belt becomes longer as much as (h-h') at both end parts of the needle 62' than that at the central part. Therefore, even when the AC voltage uniform in the width direction of the needle 62' is applied by the needle 62', an electric discharge effect to both end parts of the intermediate transfer belt is suppressed in comparison with that to the central part.  Thus, since the damage of both end parts of the intermediate transfer belt is suppressed even when the voltage is directly applied to both end parts from the separation needle 62 in the case of using a small-sized transfer paper, the both end parts is suppressed from being damaged to prevent the occurrence of defective image caused by the dielectric breakdown of the intermediate transfer belt.

The use of a combination of said agent and the black-and-white developer can achieve rapid development, but deteriorates storage stability. The use of the agent and the manganese salt or the cerium salt improves storage stability but cannot achieve rapid development.

IPC: H01L31/10
Filed: 1982-08-12
Abstract: PURPOSE:To obtain the optical reading device of excellent linearity at high speed by applying select signal inputs, which make only the specific photo diodes of a plurality of photodetecting circuits access, to an AND circuit and making the inputs access through a decode system. CONSTITUTION:When the select signal inputs 2 are at a high level, the emitter currents of a transistor 7 do not flow, a base reaches a HIGH level in a buffer transistor 8 and the transistor 8 is turned ON, and supply voltage is applied to the anode of a blocking diode 9. Charges are stored in the junction capacitance 11 of a photodiode 10. When the select signal inputs 2 are at a low level, the transistor 8 is turned OFF. Since beams are irradiated continuously to the photodiode 10, photocurrents are generated, and the charges of the junction capacitance 11 is discharged. When the select signal inputs 2 are at a LOW level, integrating charges to time of photocurrents are discharged from the charging charges of the junction capacitance 11. When the select signal inputs 2 are at a high level, charges discharged for a preceding integrating period are recharged. Signals proportional to luminous energy are extracted from an output line 3 from a peak value of the recharging currents or the quantity of charges recharged.
