IPC: G01R33/36
Filed: 1987-09-30
Abstract: PURPOSE:To enhance diagnostic efficiency, by adding three circuits, that is, a circuit for correcting the base line of a magnetic resonance signal, a circuit for correcting the sampling point of the magnetic resonance signal and a circuit for correcting the phase of a reference wave for detecting the phase of the magnetic resonance signal. CONSTITUTION:A static magnetic field magnet 1 and a gradient magnetic field forming coil 3 uniformly apply a static magnetic field and a gradient magnetic field to an object 5 to be examined. A high frequency magnetic field is further applied to the object 5 to be examined from a probe 7 under the control of a system controller 10 and the magnetic resonance signal received by the probe 7 is sent to a computer 12 through a data collecting part 11 and subjected to image reconstituting processing to be displayed on an image display 14. A reference wave phase correcting circuit 26 for correcting the phase of the reference wave supplied to an orthogonal phase detecting circuit 21, a base line correcting circuit 27 and a sampling point correcting circuit 28 for controlling the delay of the sampling clock supplied to an A/D converter 24 are provided to the system controller 10 and, since a reconstituted image by magnetic resonance can be obtained only by Fourier transform, a reconstituting time is shortened and diagnostic efficiency is enhanced.

Title: Memory data fetching system
Inventor: NAKAMURA TOKUMITSU
IPC: G06F12/00
Filed: 1987-09-30
Abstract: PURPOSE:To increase the speed of memory data fetching by selectively inhibiting memory read access and taking data subjected to a memory read address out of a read buffer when it is decided that the data read out by the memory access is stored in the read buffer. CONSTITUTION:The memory read access is selectively inhibited and the data subjected to the memory read address are taken out of read buffers 22A and 22B when it is decided that the data read out by the memory access are stored in both buffers 22A and 22B. Thus the memory access frequency is extremely reduced in case the memory read data containing continuous memory addresses is processed in a unit smaller than the data length read out by a single memory reading action. Then the memory data fetching speed is increased.

IPC: H04B15/04
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To reduce a risk of disturbance onto an electronic device with excellent sensitivity by modulating a 2nd carrier with a 2nd signal for an idle mode so as to reduce a high frequency energy propagation. SOLUTION: A TDMA radio equipment sends signal with information multiplexed onto a carrier frequency of a transmission mode channel during the transmission mode. The TDMA radio equipment continues the transmission for the idle mode and the transmission is conducted by using a different carrier frequency of a channel with a different and limited frequency. Then the resulting transmission is sent to a recipient. The signal with the information multiplexed thereon is supplied properly to an amplifier 101 and enters a modulator 105, in which the signal modulates a carrier received from a carrier frequency generator 107. The carrier frequency generator 107 generates a carrier based on a transmission/idle signal. The modulated signal is fed from the amplifier 109 to an antenna 111. Furthermore, an envelope detector 115 fives a signal representing an average RF power of the radiated signal to an automatic gain control circuit 103.

Utilizing a current from the cathode of the element 100 and mirror circuits 1 and 2, a reverse-phase current Ipda is made and added to the input of the circuit 3, thereby reducing the photocurrent Ipda. Thus, a current Iin inputted to the circuit 3 is the difference current between a photocurrent Ipd produced by the element and current Ipda, this reducing the saturation of an input transistor Q101.

Title: Pouring method with centrifugal casting machine
Inventor: UCHIDA MUTSUO
IPC: B22D13/12
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To uniformly pour molten metal from an inlet of a mold to the rear by dividing the pouring into initial period, middle period, and final period, and by pouring a small quantity in the initial pouring stage, pouring the large quantity in the middle stage, and pouring less quantity in the final stage than in the middle stage. SOLUTION: The metal quantity poured into a mold from a casting ladle is divided into three stages, initial (T1), middle (T1)-(T2) and final (T2)-(T3). To the initial pouring stage (T1), the poured quantity (V1) is made small by decreasing the tilting speed of the casting ladle. In the middle stage between (T1) and (T2), the quantity (V2) is increased by increasing the tilting speed of the casting ladle. In the final stage between (T2) and (T3), the quantity (V3) is made less than in the middle stage by decreasing the tilting speed of the casting ladle. It is preferable to pour the metal near the inlet in the initial pouring stage, pour from the center away from the inlet toward the rear in the middle stage, and pour again near the inlet of the mold in the final stage.
