Patent JP-S6461851-A (JP)
Title: Data transmission/reception system
Inventor: TAKAHASHI MASAE
IPC: G06F13/42
Filed: 1987-09-01
Abstract: PURPOSE:To double the data transmitting/receiving speed by giving the significance for each change of a handshake signal, i.e., a binary signal in an information transmission/reception system which works via the general-purpose parallel interfaces. CONSTITUTION:When the information are sent to a sub-system (b) from a main system (a) via the general-purpose parallel interfaces C, the receiving system (b) sets the RFD (ready for data) at 1 to show a ready state for reception of information. Thus the system (a) sends the first information to the system (b) and sets the DAV (data valid) at 1. The system (b) confirms the DAV and receives the information to set the DAC (data accepted) and the RFD at 1 and 0 respectively. The system (a) confirms that the DAC and the RFD are set at 1 and 0 respectively and sends the second information to the system (b) to set the DAV at 0. The system (b) confirms the DAV and receives the information to set the DAC at 0. In such a way, the significance is given even when a signal is changed to 0 from 1 for handshake. Thus the transmission/ reception is possible twice with a single handshake. As a result, the signal checking frequency is halved and the data transfer speed is double respectively.

IPC: C23C14/24
Filed: 1983-11-22
Abstract: PURPOSE:To provide a vacuum deposition device which can reduce the cost for vapor deposition and has high reliability by providing a movable deposition-preventive plate having a slit between an evaporating source and a shielding plate having a slit. CONSTITUTION:An evaporating source 6 is heated to melt and evaporate a metal 7 contained thereon while a slit 11 of a deposition preventive plate 10 is disposed in the position overlapping on the slit 9 of a shielding plate 8. The evaporated method is passed through the slits 11 and 9 and is deposited by evaporation on a base material 3 for vapor deposition under traveling on the circumferential surface of a can 4. A part 12 of the metal deposited by evaporation is stuck to the plate 10 as shown in the figure. The metal sticking thereto has weak adhesion power and when the plate is oscillated during movement, said metal is stripped and dropped by the own weight. If the stripped metal is contained in the source 6, said metal can be evaporated again and is deposited by evaporation on the base material 3. The reduced cost is thus resulted. Such an accident that the metal is stripped from the plate 10 and falls into the source 6 so as to act as an impurity during vapor deposition of the other metal is prevented.

Abstract: PURPOSE:To obtain an enclosed magnetic recorder that can reduce heat off-track phenomena and deterioration of each part of recorder with high density and high reliability, by storing the primary component elements of the recorder such as a magnetic recording medium, a head, etc. into an enclosed container together with a refrigerant which is evaporated by the temperature on the inside of the container and then condensed by the temperature on the outside of the container. CONSTITUTION:A refrigerant 21 is evaporated by the temperature at the inside of a container 3 and then condensed by the temperature outside the container 3 in an active mode of an enclosed magnetic reproducing device. The container 3 containing the primary component elements of a magnetic disk device has an opening part 11 at the side of a base 1 and is attached to the base 1 with contact secured between an end face 13 at the side of the part 11 and a side face 1a of the base 1. The temperature on the inside of the container 3 rises up in response to the rise of the temperature of the magnetic disk device. Then the heat caused by the temperature rise is received by the liquid refrigerant 21 via an inner wall 17 of the container 3. Thus the refrigerant 21 is evaporated. In this case, the inside of the container 3 is cooled by the latent heat of evaporation and vaporization. This prevents the rise of temperature of the magnetic disk device.

Title: Wire bonding mounting structure
Inventor: KOZUKA TAKESHI
IPC: H01L21/60
Filed: 1991-09-03
Abstract: PURPOSE:To provide a structure in which a short-circuit between adjacent hardly occurs even though the lead pattern is the same and stable wire bonding can be done and even if the semiconductor chip size and the number of pads are changed by separately forming a conductor pattern of a bed. CONSTITUTION:An LSI bed 4 of Fig. (b) where an LSI chip is die-bonded is an aggregation of bodies partially divided and slitted in a predetermined pattern, contrarary to a conventional bed pattern shown in Fig. (a). Therefore, warpage of a substrate due to heat generated when a die bonding agent 9 is hardened can be controlled, ensuring stabilized wire bonding. Moreover, since contact between the electrode pads of the semiconductor chip 10 and the lead electrode 3 is achieved by a wire bonding via island lead electrodes, wire loop length can be shortened. Accordingly, short-circuit between adjacent wires due to bending of wire can be prevented and mounting to a tape carrier can also be realized with good reliability.
