Title: High speed dynamic random access memory device
Inventor: ISHIKAWA TORU
IPC: G11C11/4076
Filed: 1991-12-27
Abstract: PURPOSE:To widen a range capable of high speed access like a page mode. CONSTITUTION:When the outside accesses, data read from memory cell arrays 100-130 is differential-amplified by sense amplifiers 103-133. Since sense amplifiers 103-133 hold an activated condition till a new row address is specified, the data is taken out to the outside successively only by revising a column address. Further, since a block decoder 140 revises the selection of the memory cell arrays 100-130 even by external signal B0, B1, the data capable of high speed access is widened.

Title: Method for establishing communication terminal connection and communication system
Inventor: KANDA SUKEKAZU
IPC: H04W88/02
Filed: 1999-12-20
Abstract: PROBLEM TO BE SOLVED: To limit usable terminals while improving usability by reducing labor and time for inputting identification information and evading a miss, and further allowing only a connection with a specific terminal. SOLUTION: It is decided whether a password inputted on a terminal (SLAVE (i) 20) matches a password on a terminal (MASTER 10) and when the decision result shows truth (matching), both the terminals are connected to each other. To establish the connection between the terminals, the password displayed on one terminal is viewed and the same password as the password needs to be inputted to the other terminal. If both terminals are at a distance from each other or an obstacle such as a wall is present between them, the password can not be viewed or no password can be inputted, so that the establishment of the connection with the terminal can securely be rejected.

Title: Computer system
Inventor: SATO MASAHIDE
IPC: G06F21/62
Filed: 1999-12-21
Abstract: PROBLEM TO BE SOLVED: To provide a computer system for realizing inter-OS resource protection, without providing inter-OS resource protecting mechanism which is constituted of special hardware by allowing plural OS to coexist. SOLUTION: An OS which normally operates with the highest execution authority is allowed to operate with the reduced execution authority level, so that a resource can be protected between OS, and a processor is set with an exception can be generated, when the OS performs access to the resource to be protected. Thus, the processor is informed that the OS which is allowed to operate with the reduced execution authority which tries to make access to the resource to be protected. An interrupt table for each OS is set so that emulation processing when the execution is notified can be registered, and the emulation processing to be executed when the exception is notified to the interrupt table of the OS, which is allowed to operate with the reduced execution authority is generated.  Thus, before the OS which is allowed to operate with the reduced execution authority performs access to the resource to be protected, the emulation of the access can be attained by checking whether the access is really available, so that the access to the resource to be protected can restricted.

IPC: F16L21/02
Filed: 1997-12-16
Abstract: PROBLEM TO BE SOLVED: To reliably connect mutual pipes by simple work by arranging the projecting part having an inside diameter almost coincident with a pipe inside diameter in a specific position of the main body part inner peripheral surface in a pipe joint to connect mutual pipes having a mutual interval shorter than the length of the pipe joint. SOLUTION: In connecting these pipes when a mutual interval between two pipes 7a and 7b to be connected is about 1/3 of the axial length of a pipe joint 1, first of all, the pipe joint 1 is inserted into/fitted to the pipe 7a until the right end of the pipe 7a abuts to the step difference projecting part 3a. Since the short size side length of the pipe joint 1 positioned on the right side of this projecting part 3a is slightly shorter than an interval between the pipes 7a and 7b, the pipe 7b can be arranged in a position opposed to the right end side of the pipe joint 1.  Slipping-out is prevented by engaging a slipping-out preventive piece 13 with an engaging groove 7c on the outer periphery of the pipe 7b by inserting/fitting the right side connecting port part 5 into/to the left end of the pipe 7b, by moving the pipe joint 1 inserted into/fitted to the pipe 7a to the axial directional left side in this state.

Title: Head assembly and disk apparatus with the head assembly
Inventor: KIRA HIDEHIKO
IPC: H01L29/06
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To suppress generation of dust from a head IC chip and prevent generation of head crashes by covering the head IC chip with a film. SOLUTION: A head slider 70 is loaded to a gimbal part of the leading end of a suspension 51. A bare head IC chip 80 is fixed in a face down posture to a head IC chip load part 53 at the center of the suspension 51 where the head IC chip is to be loaded. The bare head IC chip 80 is covered with a polymer poly-p-xylylene vapor deposition film 110. The polymer poly-p-xylylene vapor deposition film 110 little contains impurities and therefore little generates gases. Since the upper face 81b and all side faces 81c of a silicon chip body 81 are coated with the polymer poly-p-xylylene vapor deposition film 110, separation of a minute silicon foreign matter from the chip body 81 is limited.
