Title: Tripeptide derivative
Inventor: TANAMI TOORU
IPC: C07K14/81
Filed: 1990-03-08
Abstract: NEW MATERIAL:A tripeptide derivative of formula I (R<1> is 1-11C alkyl, tertiary butoxy of benzyloxy; R<2> and R<3> are each lower alkyl or benzyl; R<4> is H or lower alkyl; R<5> is H, lower alkyl, benzyl, etc.; R<6> is H or lower alkyl; n is 0 or 1). USE:A therapeutic drug for muscular dystrophy and vacuole-type dystal myopathy. PREPARATION:For example, a reaction is made between an amino alcohol derivative of formula II and a glutamic acid derivative of formula III (X is tertiary butoxy, etc.) followed by removing the amino-protective group and then reaction with an aspartic acid derivative of formula IV (Y is the same as X). Thence, the amino-protective group is eliminated and a desired acyl group is introduced to form a peptide derivative of C-terminated alcohol of formula V, which is then oxidized, thus providing the objective C-terminated aldehyde group-carrying tripeptide derivative of the formula I.

Title: Belt type power transmitting device
Inventor: TANAKA SHUJI
IPC: F16H7/12
Filed: 1990-03-08
Abstract: PURPOSE:To prevent slip of a belt associating with inclination of engine and drop of the transmitting ability resulting therefrom and eliminate poor performance of clutch disengagement by supporting an operational arm on the engine side, and locating a rod as opposed to the running direction of transmission belt. CONSTITUTION:During belt transmission, a force is applied to an engine pulley 26 because of the tension of a transmission belt 29 so that the engine pulley 26 is drawn in the belt tension direction, and therefore the engine 4 tends to incline in the belt tension direction. Therein an operation arm 34 is supported rotatably on the engine 4 side, and a rod 37 coupling the arm 34 with a maneuvering tool 17 is installed as opposed to the running direction of the belt 29. Therefore, the rod 37 exerts a force willing to push back the engine 4 in the direction confronting the tension of the belt 29, that hinders the engine 4 from inclining or twisting caused by the tension of the belt 29.

Title: Focusing screen for single-lens reflex camera
Inventor: HAYAMIZU YOSHISADA
IPC: G03B13/28
Filed: 1981-04-17
Abstract: PURPOSE:To make always correct focusing possible with one focusing screen for interchangeable lenses different in F number, by providing >=2 kinds of focusing elements such as prisms and cylindrical lenses to constitute the focusing screen. CONSTITUTION:Oblique views and side views of prisms and an image to be monitored are shown in figures. Fine prisms 11 and 12 consisting of two prisms 11a and 11b of an angle theta1 and two prisms 12a and 12b of an angle theta2 are so arranged that slopes of respective prisms include the same line. When a focusing screen provided with this prism group is used to focus a lens on a linear object, the linear object is seen through prisms as images 14, 14', 15, and 15'. That is, though these images are separated from one another when the linear object is out of focus, images 15 and 15' are rejected and disappear if the F number of the lens is large. Consequently, the focusing is so performed that images 15 and 15' are matched when the F number of the lens is small, and the focusing is so performed that images 14 and 14' match when the F number is large.

Title: Driving method of plasma display device and the same
Inventor: TAKAMORI TAKAHIRO
IPC: G09G3/293
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To ruduce the probability of a failure in an address discharge and to improve display quality by making a display frame for a picture composed of at least one subframe and providing a dormant period for adjusting synchronization, in a maintenance discharge period. SOLUTION: A dormant process is provided to divide the maintenance discharge process of the subframe into two, in the subframe whose maintenance discharge process is longest. In the maintenance discharge period, the second half of the previous subframe has a maintenance discharge α2, at the same time when a trigger signal of Vsync comes. Then, full surface writing and delation and an address discharge are executed and further, the first half has a maintenance discharge α1. After that, a driving sequence is temporarily stopped to put it into the dormant period. When the next Vsync comes, the left second half has the maintenance discharge α2. At this time, (α1+α2) is the same length as a conventional maintenance discharge period.  Therefore, the length of the dormant period is changed by the period of the Vsync, to obtain the working of adjusting the synchronization, with respect to the Vsync having a different period.
