Title: Input and output channel device
Inventor: INOUE MASANOBU
IPC: G06F13/42
Filed: 1981-09-09
Abstract: PURPOSE:To control a high-speed input/output transfer action in a simple way, by controlling the differential between a tag line A and its answer tay line B given from an input/output controller through a counter for an input/output channel device. CONSTITUTION:In an output transfer mode, for example, an input/output device 50 gives +1 to a register 83 every time it receives a tag line A. Now a buffer ready signal BUF-RDY is set at ''1'' and the preparation of the data to be transferred is detected. Thus an input/output interface controlling part 82 checks the state of the register 83 of that moment. If the value of the register 83 is positive, the data is fed to an input/output device 60 by the signal of a tag line B. At the same time, -1 is applied to the contents of the register 83. Then signal of the line B is transmitted in a certain period as long as the signal BUF- RDY is ''1'' and the contents of the register 83 is positive. Thus the data is transferred to the device 60.

Title: Clock circuit
Inventor: KASHIWAGI KENJI
IPC: H04L7/00
Filed: 1995-06-09
Abstract: PURPOSE: To switch a clock signal source without giving effect on a clock output by providing a PLL circuit to the post stage of a changeover circuit. CONSTITUTION: A PLL circuit 9 is operated based on a reference signal inputted by a phase comparator 6. The phase comparator 6 outputs the phase difference between the reference signal and a feedback signal from a voltage controlled oscillator 8 as an error. A loop filter 7 eliminates a high frequency component included in the output of the phase comparator 6 and outputs only a DC component in the error signal. The voltage controlled oscillator 8 corrects its oscillating signal in matching with the output of the loop filter 7. The PLL circuit 9 matches the phase and the frequency of the feedback signal with those of the reference signal at an input section of the phase comparator 6 by repeating the operation above. Thus, the operation is continued without notifying the stop of a clock signal source 1 and changeover of clock signal sources 1, 2.

IPC: H04L29/08
Filed: 1991-06-14
Abstract: PURPOSE:To reduce the burden by making a transmission request to one frame, preparing a positive response broadcast frame, and performing the broadcast transmission to a client. CONSTITUTION:A server 12 receives data almost simultaneously. A data transmitter-receiver 21 passes the frame of the received data to a server reception frame analysis part 22 at the same time. An analysis part 22 analyzes the data and requests the transmission request of the positive response ACK of each data to an ACK broadcast frame preparation part 24. The preparation part 24 makes the ACK against each data to one frame and requests the broadcast transmission against the transmitter-receiver 21. Then the transmitter- receiver 21 performs the broadcast transmission of the ACK broadcast frame to a client 11. Then the transmitter-receiver 21 reports the received ACK broadcast frame to an analysis part 17, and a data transmission confirmation part 18 confirms that the data is the requested one, resulting in reducing the burden necessary for response processing.

Abstract: PROBLEM TO BE SOLVED: To correct a luminous amount read by a read means in the case that a tilt angle of the image reader main body with respect to an image read object is changed and to control the luminous amount of a light emitted from a light source so that the luminous amount of the light exposing the image read object is made constant. SOLUTION: A reader angular velocity sensor 9 senses an angular velocity of a tilt angle of a hand scanner main body from a perpendicular state of the hand scanner main body with respect to an original X, a light source angle change detection circuit 11 integrates the angular velocity in terms of time so as to calculate the tilt angle of the scanner main body from the perpendicular state of the original X. Based on the tilt angle, the angle of the light from the light source with respect to the original X is calculated and its information is outputted to a gradation correction circuit 13.  Then the gradation correction circuit 13 corrects the gradation of a received image so that the gradation is equal to that of the image when the hand scanner main body is perpendicular to the original X based on a relation between an angle of the light from the light source emitted to the original X and the luminous amount of the light exposed to the original X.

Abstract: PURPOSE:To selectively deposite metal material on an irradiation part and form a fine wiring pattern, by selectively projecting a high energy beam on a desired portion of a substrate having an insulating film. CONSTITUTION:A semiconductor substratum 104, in which a lower layer Al wiring, an insulating layer covering it, and a through hole for connecting an upper layer Al and the lower layer Al are formed and which is to be irradiated with a beam, is arranged in a chamber 102 as an image drawing chamber.
