Inventor: UEDA FUMIHIRO
IPC: C04B37/00
Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To increase joining strength of a cutting edge piece to a tip main body by directly brazing a cubic system boron nitride sintered material-made cutting edge piece to a cutting edge part of a tungsten carbide group cemented carbide-made tip main body through a Cu alloy brazing material. SOLUTION: A composite cutting tip contains Ti: 0.5 to 10% and/or Zr: 0.5% to 10% in weight%, and also contains Ag: 1 to 5% and/or P: 0.5% to 10% according to its necessity, and a residual part is formed by directly brazing a CBN sintered material-made cutting edge piece to a cutting edge part of a WC group cemented carbide-made tip main body by using a Cu alloy brazing material having the composition composed of Cu and unavoidable impurity. A component of Ti and Zr has an action which improves joining strength by further improving wettability to a tip main body of the brazing material and the cutting edge piece.

Filed: 1990-10-29
Abstract: PURPOSE:To easily restrain the vertical motion of a cage at the time of stopping by causing contact and engagement between a cage door and a hall door via a member having a high friction factor during open and close operation. CONSTITUTION:When a cage 1 arrives at a destination floor and a door open instruction is issued, a motor 16 starts and a door link 21 is turned via a drive lever 19 and a connection rod 21. Furthermore, a small link 23 is turned and a cage door 15 is opened or closed via a shaft 26. In this case, the cam 28 of an engagement device 27 is turned in the same direction, due to the turn of the small link 23, and a cam follower 30 is pushed, thereby turning an engagement lever 31. As a result, the friction plate 34 of the engagement device 27 is clamped with an engagement plate on a hall door, in cooperation with the friction plate 35. It follows, therefore, that the cage door 15 is opened while holding the hall door. The vertical motion of the hall door is restricted and, therefore, the cage 1 becomes as if integral with the vertically restricted hall door, when the cage door 15 is opened or closed. The vertical oscillation of the cage 1 is thereby restrained.

Title: Driving method for edge emission type line head
Inventor: HARA HIROSHI
IPC: H04N1/036
Filed: 1992-10-27
Abstract: PURPOSE:To prolong service life of end emission type EL element by setting a pair of pulses of high positive and negative voltages as a minimum unit output from one common terminal. CONSTITUTION:Even if a cause for stopping function occurs in the way of application of voltage from a common terminal to an edge emission type EL element, output from a common driver can be interrupted after application of a pair of pulses of high positive and negative voltages thus prolonging service life of the edge emission type EL element. In other words, when a cause for turning a cover open switch OFF occurs during an interval after provision of COMMON 1 output from a first common terminal before application of COMMON 2 output from a second common terminal, the common driver is stopped after provision of a pair of positive and negative pulses of COMMON 2 from the second common terminal. This method stores no charge in the edge emission type EL element and prolongs service life thereof.

Title: Device for storing and sending compressed picture data
Inventor: OZAWA KAZUNORI
IPC: H04N19/60
Filed: 1990-10-29
Abstract: PURPOSE:To reduce the stored data volume to a half and to reduce the cost of a storage device by providing a selective data form conversion means which converts data from sequential data arrangement to progressive data arrangement to send the data to a transmission line in series. CONSTITUTION:All compressed moving picture data are stored in a compressed picture memory as sequential data arrangement. When the sequential sending mode is designated, a data converting part 8 transfers compressed picture data read from the compressed picture memory 4 to a line interface part 5 as it is without changing the data arrangement. When the progressive sending mode is designated, the part 8 converts the data to progressive data arrangement to transfer it to the line interface part 5. Thus, it is unnecessary to store the progressive data arrangement, and the stored data volume is reduced to a half, and the cost of the storage device is reduced.

Next an original film 58 is installed, and an operator views the vertical and horizontal directions of the image on a viewer screen 63. If it is long in the vertical direction, an image direction indication switch 201 is depressed, and if it is long in the horizontal direction, an image direction indication switch 202 is depressed. On the other hand, vertical and horizontal relation information on a copy paper P is transmitted from a paper-feeding cassette detection 203 on an output part-side to an input control part 209. The part 209 decides the rotary angle of the rotary stand 3 in an input part scan system from the signals of the image direction indication switches 201 and 202, and the signal of the paper-feeding cassette detection 203, and the rotation is performed. Thus, conditions where the operator has always to be conscious of the relation between the direction of the original image and that of the medium for operation is eliminated, and the operability is improved.
