Title: Apparatus for measuring floating amount of magnetic head slider
Inventor: MURANUSHI FUMITAKA
IPC: G01B11/14
Filed: 1989-07-24
Abstract: PURPOSE:To make it possible to measure the floating amount of a magnetic head slider from 0 to the degree of the wavelength of light used for measurement by utilizing frustrated total reflection in measurement of the floating amount. CONSTITUTION:A light path is formed in the inside of a magnetic head slider 8. Light 1 which is guided from a light source through an optical fiber 2 is inputted into a prism 5 through mirrors 4 and 3. When the floating amount of the slider 8 over a glass disk 9 is less than the degree of the wavelength of the light used for measurement, part of the total reflected light from the prism 5 is transmitted to the side of the disk as transmitted light 7 by frustrated total reflection. The total reflected light is sent into a photodetector element for measuring the amount of light as measured light (deficit reflected light) 10 by way of mirrors 6 and 4 and an optical fiber 11. When a light source is regarded as a monochrochromatic light source, the amount of light measured with the photodetector element is compared with the amount of light under the state wherein the slider is sufficiently separated from the disk 9. The floating amount is computed by a specified expression.

Abstract: PURPOSE:To quickly execute the processing by using a memory in which the count processing of the same word in a document is extremely small by providing a count object word determining means, a retrieving and deciding means, and a data writing means. CONSTITUTION:A count object word determining means 4 executes read-out successively from word data of a head word in plural word data stored in a text memory and determines it as a count object word. A retrieving and deciding means reads out successively address information of a data memory in the prescribed sequence, and decides whether each word in the text memory designated by its address information and count object word data are the same or not. On the other hand, a data writing means counts up the number of times of use corresponding to the count object word in the data memory, when the same word is retrieved. When the same word is not retrieved, address information in the text memory of the count object word and information of the number of times of use are stored in a store place in the data memory determined by the prescribed arrangement sequence. In such a way, the retrieval of the count object word and the decision of the same word or not are processed quickly.

Title: Imaging method of nuclear magnetic resonance image diagnostic apparatus
Inventor: INOUE YUJI
IPC: A61B5/055
Filed: 1988-07-29
Abstract: PURPOSE:To perform imaging due to low Gr in order to improve an S/N ratio by applying an exciting pulse having the frequency band width corresponding to the section width of an unnecessary region before sequence for performing regular scanning. CONSTITUTION:When an exciting pulse 9 is applied in a section A, only an unnecessary region DELTAL is excited. In the succeeding section B, an imaging region FOVi is sliced by a slice gradient 3 to receive an exciting pulse 1. In an unnecessary region 12, a frequency encoded gradient magnetic field Gr1 10 is applied and said region 12 is only excited by the exciting pulse 9 and no gradient for aligning a phase is applied. Therefore, no effective signal is issued like the spin in the imaging region FOVi excited by the pulse 1. As a result, even when Gpr is a low gradient, at a place of Z>20cm outside the imaging region FOVi, aliasing such that the signal of the same frequency as that within the region FOVi is received by an RF coil is not generated.

Title: Frequency synthesizer
Inventor: KAWAGUCHI KOJI
IPC: H03L7/18
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To prevent increase in both scale and cost of a circuit and always to set an optimum filter constant over a wide variable range of HF bands by using a switched capacitor filter whose cutoff frequency varies in response to a clock of the frequency that is accordant with the frequency information. SOLUTION: An SCF(switched capacitor filter) 10 consists of a MOS capacitor, a MOS switch and a MOS operational amplifier and is used as a loop filter. The cutoff frequency of this filter is decided based on the capacitor ratio and the clock frequency 'fck' and can be varied by changing the frequency of an external clock 'fck' that turns on and off the MOS switch. Thus, the cutoff frequency can be freely adjusted by the clock 'fck' and by means of the SCF 10. Thereby, it's possible to vary the transmitting frequency over a wide range with its stable characteristic maintained by managing the clock 'fck' in response to the frequency information of the external clock.

Title: External character processing method of word processor
Inventor: UMEMURA MASAO
IPC: G06F17/21
Filed: 1983-10-14
Abstract: PURPOSE:To prevent the external characters under use from being deleted by a user for the external character processing of a word processor, by discriminating the use or non-use of the external characters which are used to all sentence within a file and displaying the results of said discrimination. CONSTITUTION:A CPU1 decides the number of the pushed external character on a keyboard 9 and converts this number into a corresponding character code to store it to video RAM3. For registration of an external character pattern, the registration of characters is indicated by character keys and a word processor is set under a register mode for external characters. Then an external character pattern is formed in a lattice pattern of 24X24 matrices and recorded to an RAM6 together with the numbers of external characters. These numbers are stored to an external character number table within a main memory 2, and the external character number table once registered is stored to an FDD to avoid its erasion. The keyboard 9 is operated to set an external character display mode, and the unregistered external characters and the unused characters in a document are displayed with marks different from each other. If the erasion is desired to a certain character, a cursor is shifted to the relevant character position and a deletion key is pushed.
