Title: Microcomputer
Inventor: WATANABE KATSUMI
IPC: G06F13/42
Filed: 1990-10-25
Abstract: PURPOSE:To allow or inhibit the output of a signal indicating the start of a bus cycle by allowing a bus cycle start signal generator to input an internal timing clock signal and a trigger signal and output a bus cycle start delay signal corresponding to an external timing switching input signal corresponding to an external timing switching input signal. CONSTITUTION:The bus control structure of a microcomputer(MC) to be used in a development supporting device includes a timing signal generator 102 for inputting a cycle request signal and a timing clock signal and supplying a trigger signal to a bus cycle start signal generator 113. The generator 113 inputs an internal timing clock signal and the trigger signal and outputs a bus cycle start delay signal correspondingly to an external timing switching input signal. Namely, the output timing of a signal indicating the start of the bus cycle can be delayed from the output timing of an address signal. Consequently, the permission or inhibition of the output of the signal indicating the start of the bus cycle to the outside of the development supporting device can be controlled by utilizing the delay time.

Abstract: PROBLEM TO BE SOLVED: To provide a multiple connection system screw-type terminal device which is satisfactory in operability in assembly work, decreases the ratio of inferior products so as to decrease cost, and does not need a large space for installation, owing to its compact size. SOLUTION: Each rotary tongue 25 is projected from a top of a cylindrical housing part 21 so as not to move along an axial direction of the housing part 21, where the cylindrical housing part is provided in a single body with a body plate 20. A bar-shaped contact 30 is inserted into a bar-shaped contact insertion hole 24, which is opened in the center portion of the rotary tongue 25, so that the bar-shaped contact will not rotate in relation to the rotary tongue 25 but moves along the axial direction. A terminal plate 41 is fixed at a bottom of the housing part 21. A screw shaft 32 is screwed in a female screw hole 46 made on the bottom. By rotating the bar-shaped contact 30 accompanied by the rotation of the rotary tongue 25, the screw shaft 32 moves in the axial direction thereof, in relation to the terminal plate 41.  A conductor-gripping part 31 advances and retreats in the direction opposite to the direction of the terminal plate 41.

Title: Test circuit for semiconductor integrated logic circuit
Inventor: OZAKI HIDEHARU
IPC: H01L27/04
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To test a logic circuit generating a control signal easily by outputting an output control signal of a tri-state buffer as a data in response to a switching signal. SOLUTION: When a test switch signal 5 is turned into test mode, output signal from a control circuit 6 is delivered to the input terminal of a tri-state buffer 1 through a selector 4. A selector 3 then selects an input of high level 10 to make a control signal 7 'H' and delivers the output value from the control circuit 6 to an output terminal 2 regardless of the value of an internal data 9. The control circuit 6 can be tested directly by comparing the output value with the 'H' level of expected output value. Furthermore, even when the control circuit 6 outputs an 'H' level erroneously due to failure instead of an 'L' level, output from the control circuit 6 can be tested directly by switching the test switch signal 5 to the test side.

Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To prevent the wrong use of an application program by carrying out the execution control program stored in a ROM and then carrying out a function module only when an execution code is coincident with a cancel code. SOLUTION: The user code stored in a disk device 13 is compared with the user code stored in a ROM 11, and the same user code is stored in the device 13 and the ROM 11 respectively. Under such conditions, it is decided that both device 13 and the ROM 11 are coincident with each other. Then every function module included in an application program is carried out only when the coincidence of user codes is secured between the device 13 and the ROM 11 and also the term of validity of the code stored in the ROM 11 is not expired yet. Therefore, only a computer that has the ROM 11 storing an execution control program can carry out the function modules even when the application program stored in the device 13 is illegally duplicated.
