Title: Shearing device
Inventor: IMAI KATSUYA
IPC: B23D33/10
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To prevent burrs from being caused by forming a contact end on a stopper so that the region to be brought in contact with the tip of a material to be sheared may be in the moving range of a movable shearing blade until the shearing or the completion of the shearing, and so that the other region may not be brought in contact with the tip of the material to be sheared. SOLUTION: A material to be sheared W is supported in the region A1 on the contact end surface of a stopper 1 for the time from the time that a moving shearing blade 3 starts the shearing operation to the time that the actual shearing is completed. After that, the sheared material is moved until the all operation strokes of the moving shearing blade 3 are completed, the end surface of the material faces to the non contact region A2 of the stopper 1, the frictional slide movement is not generated between the material and the contact end surface, and therefore, seizure and burrs are not caused on the sheared material.

Title: Ion flow generating type electrostatic recorder
Inventor: URATA MANABU
IPC: G03G15/22
Filed: 1986-10-30
Abstract: PURPOSE:To prevent image density from being varied due to the variations in characteristics of an ion flow generating means or the variations in temperature, humidity or the like, by detecting the surface potential of an electrostatic latent image forming material, and controlling a driving voltage for the ion flow generating means according to the result of the detection. CONSTITUTION:Under the condition where a photosensitive belt 2 is made conductive by turning ON a light-emitting diode array 180, a voltage VD=3KV is applied to a driving electrode 31 while a voltage VS=-1,000V is applied to a screen electrode 32, and a negative DC voltage is applied sequentially to each divisional unit of controlling electrodes 32 from a power source 38 for the controlling electrodes through a divisional driving circuit 186. In each divisional unit, the voltage at the controlling electrode is controlled based on an output from a voltage-detecting circuit 181 so that the current flowing through a resistor R becomes 10muA, and the voltage is stored into a nonvolatile RAM as a set voltage. In a copying operation, a writing head 5 is controlled based on the set voltage stored in the nonvolatile RAM. Since driving voltages are divisionally controlled so that ion flows become uniform throughout the writing head, the uniformity of developed density is ensured.

Title: Ink supplying device
Inventor: TAKAGI ATSUSHI
IPC: B41J2/175
Filed: 1993-09-22
Abstract: PURPOSE:To provide an ink supplying device in which a volumetric efficiency of ink is improved by suppressing influence of stabilization of ink supply performance and peripheral environmental change. CONSTITUTION:An ink tank 2 is formed therein of a main ink chamber 4 and a sub-ink chamber 6 in which an absorbing member 9 is disposed in such a manner that an atmospheric communication hole 8 is formed at an upper part of the chamber 6. The member 9 holds an ink pressure constant by its own capillary force. As ink is consumed, the ink in the chamber 6 is initially consumed. When a predetermined ink amount is consumed, as the air is passed through the member 9 to pass an ink core member 10, it becomes bubble to move toward the chamber 4, thereby maintaining the ink pressure constant. The member 10 is always brought into contact with the ink, and hence a meniscus is not damaged. A recess 11 is formed on a periphery of a bottom of the chamber 5 to trap the air invaded from a side of the chamber 6, and the ink in the chamber 6 can be wasted out.

Title: Feeding device for paper
Inventor: MAKITA NOBUHIRO
IPC: B65H1/26
Filed: 1987-10-14
Abstract: PURPOSE:To surely feed a thick sheet of paper without causing non-feeding and the occurrence of jam by providing a hook for engaging a paper push-up plate with a friction pad to separate the end part of the paper push-up plate from a paper feed roller. CONSTITUTION:At the time of feeding a thick sheet of paper 4', as a friction pad 12 is moved in the direction of being separated from a paper feed roller 5, a hook 20 is engaged with a holder 11 to separate the end part of a paper push-up plate 6 from the paper feed roller 5. As the end part of the paper push-up plate 6 is separated from the paper feed roller 5, a slide plate 21 is floated up above the top face of a pad 18 and the sheet of paper 4' is pushed against the bottom face of the paper feed roller 5 by the slide plate 21. At this time, since the friction coefficient of the slide plate 21 is small, the friction resistance between the slide plate 21 and the sheet of paper 4' is smaller than the delivering force by means of the paper feed roller 5. Hence, the occurrence of non-feeding or jam can be prevented surely delivering the sheet of paper 4'.

Abstract: PURPOSE:To facilitate the insertion to a blood vessel and the highly precise measurement of a blood vessel internal pressure by providing at least a double structure consisting of a first tube and a second tube inserted therein, providing a balloon operated through the former, and forming at least a part of the latter from an ultra elastic allay. CONSTITUTION:As the material of a core tube 4, an ultra elastic allay, for example, shape memory alloy, is used. When its form is made linear and stored, a catheter 1 can be easily inserted even in a curved position of a blood vessel. When an intra-aortic balloon (IAB) catheter 1 is inserted through the femoral artery, its top end is passed through the curved part of the artery, in which the resistance received by the IAB catheter 1 is slight, and the insertion is easily conducted. The pressure sensor of the core tube 4 detects the blood vessel internal pressure, and as the pressure sensor is supported by the core tube 4 of the inflexible shape memory alloy, the blood pressure can precisely be detected without being absorbed by the core tube 4. Thus, the medial treatment can be safely and certainly performed.

Title: Semiconductor package
Inventor: TERAJIMA SEIJI
IPC: H01L23/28
Filed: 1991-10-08
Abstract: PURPOSE:To provide a semiconductor package which prevents the curvature of a lead, in the semiconductor package in the shape of the lead of the gal wind corresponding to surface mounting. CONSTITUTION:In individual semiconductor packages wherein semiconductor chips are sealed, they are constituted of the shapes of such lead frames that the longitudinal rigidity of the slant parts of the leads decreases and that the lateral rigidity increases at the lead parts which have gal wing parts contacting with a board. This obviates the necessity to perform the external appearance check severely before mounting it on a board, and the process of lead rectification can be omitted. As a result, by the rationalization of the manufacture process, the package assembling can inexpensively be done. Moreover, the soldering between the pattern of the board and the terminal of the package at mounting can surely be performed, thereby contributing greatly to the quality improvement of the board.
