Filed: 1992-08-07
Abstract: PURPOSE:To improve mechanical strength by forming a core chip so as to constitute a magnetic circuit provided with a gap part joined with an I core and C core consisting of a magnetic metal oxide material and joining a reinforcing member provided with a coil groove to the I core. CONSTITUTION:The core chip 1 is formed by combining the I core 2 and C core 3 consisting of the magnetic metal oxide material, such as single crystal ferrite, and a reinforcing member 4 consisting of a nonmagnetic material, such as ceramics. A gap part which is formed of glass and has a track width W1 to execute an electromagnetic conversion operation is formed on the front surface 1a thereof. The cores 2 and 3 are bonded to constitute the magnetic circuit of the closed circuit and are reinforced by a bonding-glass 6. The member 4 is joined to the trading surface side of the core 2. This trading surface 1b is provided with a coil groove for winding an electromagnetic conversion coil. As a result, the mechanical strength of the core 2 is improved, and therefore the failure of the core 2 at the time of winding the coil is suppressed.

Title: Hot runner-valve gate die
Inventor: OZAWA HIROSHI
IPC: B29C45/28
Filed: 1998-07-27
Abstract: PROBLEM TO BE SOLVED: To provide a hot runner-valve gate die in which the gate treatment face of a molding is made to such a smooth face that the remainder of a gate and a burr do not remain and the molding free from residual stress is obtained. SOLUTION: The hot runner-valve gate die is equipped with a valve pin 17 which opens and closes a gate hole 16 of the body 15 of a nozzle opened in the molding part 14 of a product by means of movement in the axial direction. Injection and filling of molten resin 21 into the molding part 14 of the product is controlled by opening, closing and driving the valve pin 17 by using oil pressure as a driving source. The hot runner-valve gate die is equipped with a high-speed changeover valve 12 which vibrates the valve pin 17 in the axial direction. The valve pin 17 is formed so as to be transferred from an opened state to a closed state while being vibrated by the high-speed changeover valve 12.  Since the valve pin 17 surely reaches the inside of the gate hole 16 and closes it, the remainder of a gate and a burr do not remain on the gate treatment face of a molding 1 and the gate treatment face is finished into a smooth face.

Filed: 1985-09-27
Abstract: PURPOSE:To improve the transmission efficiency by sending a data depending on the stored quantity of a picture data to a flow buffer, or the generating speed of a coded data and the transmission state of the picture data to the line. CONSTITUTION:In starting a picture data fetch, in case of an original with a few number of coded bits, data are not filled in a memory block unit. Thus, the time loss is taken into consideration and a proper timer supervises the time loss, and even when the memory block unit is not occupied, in case of timeout, the data stored so far in the memory block unit is informed as a trans mission frame request. When the picture data is fetched fully in the memory block unit without timeout, a FIFO counter checks the state and when the FIFO counter is not '0', the memory block unit is linked with the next memory block unit to fetch the picture data from the buffer memory again.
