Title: Magnetic resonance imaging apparatus
Inventor: MATSUI TORU
IPC: G01N24/00
Filed: 1989-09-22
Abstract: PURPOSE:To process an unrestricted tomographic image by adding a conversion processing function, by which an operator inputs an inclined magnetic field time-intensity table for forming an inclined magnetic field sequential data and an RF pulse transmission timing data for transmitting RF pulse in a form of table into a central operation processing unit optionally. CONSTITUTION:When a processing of a new sequence wave-form generation is started up, a central operation processing unit 6 displays an initialized operator input-output inclined magnetic field wave-form data and requests an operator to input a new one. If the operator inputs an operator input-output inclined magnetic field data 30 of an inclined magnetic field pattern, the central operation processing unit 6 will interpret it as an inclined magnetic field sequence 31 and convert it into an inclined magnetic field current time series data by clocking it. Moreover, an inclined magnetic field time series data which has already been transferred to a sequence controller 4 is read and converted into an operator input-output inclined magnetic field data table for operator input- output, and an inclined magnetic field sequence wave-form data is re-edited based on that data. It is possible, therefore, to process an unrestricted tomographic image.

Title: Developing roller
Inventor: FUKUDA SUSUMU
IPC: F16C13/00
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To provide a characteristic for preventing filming with toner and to improve durability by specifying each capacitance of the whole of a developing roller and an elastic layer. SOLUTION: The elastic layer 3 is concentrically provided on the periphery of a shaft made of metal such as SUS and an aluminum alloy and the outer periphery of the elastic layer 3 is covered with a surface layer 4. In such a case, there is a case where a resistance adjusting layer for adjusting the electric resistance of the developing roller 1, a primer layer for improving the stickability between the elastic layer 3 and the surface layer 4, etc., are included therebetween. Then, the developing roller 1 is constituted so that the capacitance C1 of the surface layer 4 after the covering has a value of <=2.5 nF and the capacitance C2 of the elastic layer 3 has a value of 0.8<=20 nF. Therefore, the filming with the toner on the surface of the developing roller is prevented.  Thus, on the surface of the developing roller, a uniform thin toner layer only of the toner contributing to development can be formed.

Title: Frequency characteristic correcting circuit
Inventor: KITAGAWA SHIGERU
IPC: H03G5/02
Filed: 1984-11-20
Abstract: PURPOSE:To realize high S/N and low noise by controlling an attenuator in response to an output level of plural filters connected in parallel with an input terminal. CONSTITUTION:A signal fed to the input terminal is divided into two; one is given to a subtraction circuit 1b through an amplifier 1 and the other is fed to BPFs 3-N connected in parallel with the amplifier 1. When the applied signal does not include a frequency component over f5 (f3-fN are the center frequencies of each BPF), an output is obtained from the BPFs 3, 4 but no output is given from the BPFs 5-N. Thus, level detection circuits 3b, 4b discriminate that a signal is outputted to turn off attenuators 3c, 4c and bypass the signal and level detection circuits 5b-Nb discriminate that no signal exists to turn on attenuators 5c-Nc. Thus, the nose generated in the BPFs 5-N is not added by the addition/subtraction circuits 1a, 1b, the signal is free from noise and the noise at no signal is only the noise generated from the amplifiers 1, 2.

IPC: H01L23/28
Filed: 1988-09-29
Abstract: PURPOSE:To prevent separation of a resin mold layer from a semiconductor element and a semiconductor mounted section due to thermal stress by forming side walls around the semiconductor mounted section. CONSTITUTION:A lead frame used as an outer frame 1 has a semiconductor element mounted section 2 and side walls 8 surrounding the semiconductor element mounted section 2, the upper end of the side walls 8 being higher than the boundary plane between the top face of a semiconductor element 5 and a resin mold layer 7 and the lower end of the walls 8 being lower than the boundary plane between the bottom face of the mounted section 2 and the layer 7. By using such lead frame, any stress exerted from the layer 7 outside the walls 8 is blocked by the walls 8 and therefore stress acting on the boundary plane between the top face of the element 5 and the layer 7 and on the boundary plane between the bottom face of the mounted section 2 and the layer 7 due to thermal stress is reduced. Accordingly, removal of the resin mold from or sliding of the resin mold in the boundary planes can be prevented effectively.

Abstract: PURPOSE:To track correctly a light pen by a cursor and to read correctly the position on the screen by executing the displaying only corresponding to the cursor at least on the scanning line selected for a frame in the area in the vicinity of the cursor. CONSTITUTION:At the circumference of a cursor 6, an interlaced scanning area of a small scope is provided, the whole of the cursor 6 is displayed together with respective frames in the area, and user data 7 are divided into even and odd scanning lines. The data 7 on the odd line go to be blank by every other frame, and on the other hand, on the even line the data go to be blank by respective frames during the time. While the odd line is blank, only a contact point on the odd line goes to be a cursor corresponding point, in the same way, at respective frames during the time, the contact point on the even line goes to be a corresponding point. When the contact point on the odd line is accepted at a certain frame, the contact point on the even line is not accepted. At the frame before and behind it, the reverse action is executed. Consequently, correct information is obtained by respective frames, and a relative displacement to the center of the sight of a light pen 3 is counted from the cursor. For this reason, the cursor can track the action of the pen.

Title: Power detection circuit
Inventor: KOMURO KENJI
IPC: H03D1/00
Filed: 1988-09-30
Abstract: PURPOSE:To accurately detect the resultant power of two input signals even when the input signals have respectively different frequencies by respectively and separately squaring the peak value of the AC component and the DC component of the output of an envelope detector and adding respective squared results after that. CONSTITUTION:When two signals Acosomega1t and Bcosomega2t (A>B) having the respectively different frequencies are inputted, the output of an envelope detector 1 becomes an AC waveform having the maximum value A+B and the minimum value A-B with A as its approximate center. When this signal is inputted to a low-pass filter 2 and passed through a square amplifier 5, the output of the amplifier 5 becomes a value proportional to A<2>. At the same time, another value proportional to B<2>, the square of the peak value of the AC component of the output of the envelope detector 1, can be obtained by taking out the AC component by a DC cutting capacitor 3 and passing the AC component through a peak detector 4 and a square amplifier 6. Further, when the respective outputs of the square amplifier 5 and the square amplifier 6 are level-adjusted by variable resistors 7 and 8 and added in an adder 9, an output proportional to A<2>+B<2> can be obtained. Thus the power of the two signals can be accurately detected.
