Abstract: PURPOSE:To make ultrafine feeds possible by rotating relatively a nut which is screwed on a screw threaded shaft, through two pairs of gears, a spline shaft and a cogged belt pulley. CONSTITUTION:A nut 1 is moved in the direction of an axis by rotating a screw threaded shaft 2 by a motor 6, and the nut 1 is rotated in the same direction with slight difference of the relative rotating speed, through a one-way clutch 15, two pairs of gears 8, 9 and 10, 11, an electromagnetic brake 16 which is on in a normal feed, a spline shaft 4 and a cogged belt 14c which is loaded on pulleys 14a, 14b, and ultrafine feeds are made. In this case, the difference between the number of teeth of the gears 8, 9 and the difference between the number of the teeth of the gears 11, 10 are made equal, and the numbers of the teeth of the gears 8, 11 are set different from each other and the numbers of the teeth of the gears 9, 10 are set different from each other. Thus ultrafine feeds of a table 17 about 1-2mum/m per one revolution of the screw threaded shaft 2 are made possible.

Title: Electronic equipment with floppy deck
Inventor: OONO TAKIO
IPC: G06F3/06
Filed: 1984-02-06
Abstract: PURPOSE:To prevent a device from being unusable and enable to use the device continuously by using the second floppy deck by a changeover switch if it is impossible to use the first floppy deck which reads a program. CONSTITUTION:The program which reads the state of a changeover switch 10 is incorporated in a ROM4; and when a power switch is turned on, a program is read by a floppy deck FDK#1-8 if the changeover switch 10 is turned on. If the first FDK#1-8 is faulty, the changeover switch 10 is turned off. The ROM4 reads this state, and the program is read from the second FDK#2-9. Since only one FDK#2-9 can be used, an apparatus cannot be used as an office computer but can be used as a cash register. Since the apparatus can be used as a cash register while the FDK#1-8 is repaired, business in a counter is not confused.

Title: Method of reading asynchronous received data
Inventor: OTA HIDEKI
IPC: H02H3/28
Filed: 1995-02-08
Abstract: PURPOSE: To reduce the number of interrupting wires for reading word data from the region of each channel of memory at a protection relay station for processing by using frame data of the same number from all the stations after transferring transmitted data to a memory region with 6 words in one frame by station having a phase deviation at the time of arrival which were generated from a plurality of stations in synchronization at constant time periods while commonly updating the frame No. CONSTITUTION: A memory region 9M-1 of a channel #1 reads the data of 6 words of all the channels of a memory 9 to the application 3 side by the timing 11 with one frame established with word data A(n) to F(n) of No. n. A batch read processing 13A produces word data for one frame coinciding with the frame No. in alignment with the data read previously for each channel and sends them to a synchronous data extract processing 14. The processing 14 extracts data which can be established by the frame No. n-1 throughout all the channels and sends them to the arithmetic processing.

Title: Impact wave generator
Inventor: HERUMUUTO RAIHIENBERUGAA
IPC: G08B19/00
Filed: 1986-01-31
Abstract: The shock wave generator preferably includes a primary coil with preceding secondary diaphragm. The primary coil is acted upon with a current pulse by discharge of a capacitor via a spark gap, whereby a shock wave is triggered. The time response of the discharge current is determined with a measuring resistor and supplied to the first input of a first comparator. To the second input of the comparator a reference value is supplied. If the difference between the measured value and the reference value exceeds a given value, an alarm signal is given, which actuates e.g. an alarm signaling device and/or blocks the triggering of additional shock waves. The pressure response of the shock wave at given points of the path is determined by means of pressure pickups and another comparator. An excessive difference from an expected pressure reference value leads to an alarm signal. An advantage of the safety measures is that a deterioration of the electrical contacts of the spark gap, short circuits in the primary coil, deformations of the secondary diaphragm, gas accumulations in the shock wave generator and other irregularities can be recognized in good time.

Title: Magnetic recording medium
Inventor: HONMA TAKUMI
IPC: G11B5/842
Filed: 1992-01-10
Abstract: PURPOSE:To provide a magnetic recording medium having enhanced surface smoothness and fit for short-wavelength recording. CONSTITUTION:The surface roughness of a magnetic layer is reduced by reducing the thixotropy of a magnetic coating material used at the time of forming the magnetic layer by coating. For example, in order to attain <=0.010mum surface roughness Ra of the magnetic layer, the thixotropy of the coating material is reduced to 450g.cm.rpm. The thixotropy is calculated from the area of the hysteresis loop of a torque curve drawn at the time of increasing or decreasing the number of rotations to 1,000rpm in 1min with a viscometer using a rotating double-tubed cylinder having 21mm outside diameter of the inner tube, 50mm length and 22mm inside diameter of the outer tube.

Title: Heating cooker
Inventor: MITSUMOTO YOSHIO
IPC: F24C7/04
Filed: 1987-01-30
Abstract: PURPOSE:To prevent a disturbance in heating and a stain on a heating chamber by a method wherein an area of which temperature reached to a heating chamber wall temperature in which food garbage or oil stains can be completely burnt is coated with an inorganic coating film and other areas having a lower temperature are coated with an organic film, an interfacing part between these portions is provided with a certain step at the bottom wall of the heating chamber. CONSTITUTION:As a heating operation is promoted and a plane heater 8 is heated, a projecting part at a bottom surface of a heating chamber 1 is instantaneously heated up to a high temperature. The bottom wall is formed into a frustam by a drawing work, and so a deformation of the wall is scarcely formed. Since a radiation coating film layer 12 composed of ceramic and the like is applied in an inner wall of the projecting part, a thermal radiation is improved and an efficiency is improved more and at the same time dews of food splashed from a heated item 5 and flowed into the chamber can be instantaneously burnt out during heating operation. Inner surfaces of side walls of the heating chamber 1 contain fluorine and they are coated with films 14 of material quality with a high radiation factor, so that the stain may not be adhered to the surfaces and the stains may be easily wiped off. In addition, a distribution of temperature in the heating chamber 1 and a heater body 8a is designed in such a way as an interface line P between the coating films 12 and 14 occupies a midway part of a stepped part 17 of the bottom surface.
