Patent JP-H02268197-A (JP)
Title: Novel peptide and intermediate for production thereof
Inventor: YAMAMURA TAKESHI
IPC: C07K5/103
Filed: 1989-04-07
Abstract: NEW MATERIAL:A peptide of formula I (Boc is t-butyloxycarbonyl; Acm is acetamidemethyl; ONSu is N-oxysuccinimide). USE:A ligand for peptide metal complexes for medicines or functional materials. PREPARATION:For example, a 4M-hydrochloric acid/dioxane solution is added to a terminal amino group-protected oligopeptide of formula II (Me is methyl) to remove the protected amino group followed by reaction with a compound of formula Boc-Val-OH in the presence of a condensing agent and then reaction with a compound of formula Boc-Cys(Acm)-OH by similar means, thus forming a peptide of formula III. Thence, this peptide is treated with 1M NaOH in methanol to remove the protected carboxyl group followed by reaction with N-hydroxysuccinimide in the presence of a condensing agent, thus obtaining the objective peptide of formula I.

The surface protective layer consists of a hardening resin by the combination of a radical polymerizable compd. and an ion polymerizable compd. Thus, the obtd. photoreceptor has excellent environmental stability and can produce high quality image even after repeatedly used. The electrophotographic device is equipped with this electrophotographic photoreceptor.

Filed: 1990-04-04
Abstract: PURPOSE:To securely and easily fit a body to be tested on the torsion testing machine by forming tip-split type slits in tip parts of plural claws projecting from the inner peripheral part of a chuck main body toward the center. CONSTITUTION:The chuck 1 is constituted by projecting the claws 3 inside the annularly sectioned chuck main body 2 from three directions to the center and the claws 3 are fitted slidably inside guide grooves 4 formed in the chuck main body 2 while restrained from rotating.

Title: Production of bead wire
Inventor: SHIBA TAKESHI
IPC: B29D30/40
Filed: 1985-04-25
Abstract: PURPOSE:To eliminate the variance in the copper deposition onto a bead wire by measuring the copper deposition on the bead wire during traveling between a copper plating cell and coiler and controlling the coiling speed of the coiler. CONSTITUTION:A steel wire 2 let off from a let-off reel 1 is passed through a hydrochloric tank 3 and a washing tank 4 and is plated with copper in a copper cladding bath cell 5. The wire is then passed through washing tanks 6, 7 and a hot washing tank 8 and is dried with a dryer 9. The deposition of the copper plated on the steel wire is measured by an energy dispersion type X-ray fluorometer 12 and the speed of the wire 2 is detected by a speed detector 15, then the relation between the plating speed and deposition of the steel wire is calculated at the speed at which the target deposition is attained by a microcomputer 13 so as to attain the target deposition. The result is fed back to a motor 14 for driving the coiling, by which the wire speed is controlled. The wire is thus plated with optimum copper deposition and the decreased variance thereof.

Title: Image forming device
Inventor: ISAKI HIROFUMI
IPC: G03G15/00
Filed: 1990-04-06
Abstract: PURPOSE:To reduce the need of recopying by providing a 1st storage means capable of rewriting the control data of a driving means and a 2nd storage means storing data selected in accordance with the state of a recording medium and controlling the quantity of charge supplied to the recording medium based on the data stored in the 2nd storage means. CONSTITUTION:A process control circuit 70 is provided with a storage device RAM 74 storing data with which the acting state in the case of initialization by turning on a main power source is regulated and a storage device RAM (SRAM) 75 storing electrostatic charging output rank data Dn based on time data. The rank data Dn is rewritten to the data regulated based on the time data accessed from the ROM 73 even while a copying action is dormant or interrupted. On the other hand, in the case that the main power source is turned off and turned on again thereafter, the data storing in the RAM 74 is reset to be in an initial state. Therefore, the data with which the output is controlled is changed independently of the initializing action regulated by turning on/off of the main power source. Thus, the need of recopying is reduced and copying cost is made low.

Title: Photosensitive mixture and method of forming pattern by using that
Inventor: MORISHITA HAJIME
IPC: G03C1/52
Filed: 1980-07-04
Abstract: PURPOSE:To simplify the formation of a fluorescent surface by exposing a photosensitive film,  which coats the inner wall of a panel, contains an aromatic diazonium salt as a photosensitive component, and develops adhesiveness by exposure, to light so as to make a given pattern to be  formed, before a phosphor powder is made to touch the phosphor film. CONSTITUTION:An aromatic diazonium salt is represented by the general formula: R1 and R2  represent a straight chain alkyl group; X, Y and Z represent either H or a straight chain alkyl  group; the salt contains less than two H. The aromatic diazonium salt is added with 0.5- 500wt% of an organic high molecular compound and 0.01-1wt% of a surface active agent to  make a mixture solution, and the mixture solution is applied to the inner surface of a panel and is  dried, thus a paint film being formed. Thus formed paint film is exposed to light of a given  pattern to make the exposed part tacky, before a phosphor powder is made to contat with the  paint film, thereby making the exposed part to be coated with the phosphor. An excess of the  phosphor powder remaining on the paint film should be removed. Following that, the process  mentioned above is carried out with phosphors of the other colors. By the means mentioned  above, the process of forming a fluorscent surface can be simplified.

Filed: 1985-04-26
Abstract: PURPOSE:To prevent any damage to a wafer and a takeout arm from occurring at the time of takeout operation, by applying light to each wafer mounted on plural stages inside a carrier, while detecting the attitude. CONSTITUTION:Each of wafers 3a-3l is horizontally placed on plural stages 2a-2a'-2l-2l' of a carrier being mounted on a pallet 1 moving in an arrow A direction, and a front opening 2M and a rear opening 2N opposed to the former are set down to a takeout port of these wafers and each passage of light out of projectors 6a and 6b parallelly set up in horizontality. When these wafers 3a and so on are righteously mounted on these stages 2a-2a', each output of light receivers 7a and 7b is largely reduced together but, for example, when the wafer 3c is placed aslant between both third and fourth stages 2c and 2d, the output of the light receiver 7a is small while the output of the light receiver 7b is large whereby it judges that an attitude of the wafer 3c is not righteous, emitting a warning and stopping other motions, and an operator remounts it for a righteous attitude.
