Title: Automatic playing device
Inventor: MITARAI TAKESHI
IPC: G10H1/00
Filed: 1989-01-11
Abstract: PURPOSE:To perform correction in a short time by making reverse sound production by reading out musical sound information recorded in a memory in an opposite direction so that a point to be corrected can be searched in a short time and newly inputting the musical sound information after canceling the reverse sound production in finding the point to be corrected. CONSTITUTION:A sound recording state can be stated immediately while a melody recorded in a sound recording section 8 is reproduced by making rewinding by operating a reverse switch 1B and a key operation in the course of sound reproduction. In other word, when a key 'ON' is discriminated, a process for shifting to the sound recording state is performed. A full-adder 30 tentatively executes subtraction for subtracting the current time data of a RAM 5 from the cumulative time data of an NE latch. Then the NE latch latches the newly calculated time data and transfers the data to a PR latch 11. The full-adder 30 is returned to the adding operations and a subtracted result of a subtractor 14 is written in the RAM 5 so as to advance the address by one. Thus the correction can be performed smoothly and a new sound recording information inputting state is set in a short time.

Abstract: PURPOSE:To enable to perform a correct measurement of brightness of a dynamic lighting in consideration of visual response of a luminous color, by a method wherein a visual response is made approximate to a primary delay element which is selected at each color of monochromatic light of a LED. CONSTITUTION:With a control pulse CP1 applied to a current source circuit 11, a transistor Q1 is energized for a period T2, and a LED does not light ON. The Q1 is brought to OFF during a period T1, and the LED lights ON.

Title: Rotor with magnet for rotary electric machine
Inventor: TAKAHASHI MIKIO
IPC: H02K1/27
Filed: 1990-01-10
Abstract: PURPOSE:To make fine iron pieces to hardly adhere on a magnet by providing side plates made of a nonmagnetic material at both sides of a rotor core in such a manner that at least part of the side plate is present in the lateral width of a stator core. CONSTITUTION:Side plates 10 formed in a disclike state of a nonmagnetic material are engaged with a shaft 6 at both sides of a rotor core 7 to be brought into close contact with a magnet 9. Further, the core 7 is disposed partly at least in the thickness of the side plate 10 within the lateral width of a stator core 2.

Title: Method for controlling shape
Inventor: KAWASE HIROSHI
IPC: B21B37/38
Filed: 1987-01-12
Abstract: PURPOSE:To improve the rolled stock shape between stands and to improve the easiness for sheet passing by detecting the shape of a rolled stock by shape detectors, calculating a work roll bending force and a leveling amount of a rolling mill by a prescribed equation, and correcting the above two amounts for the succeeding stock. CONSTITUTION:Shapes of a rolled stock between respective rolling mills (stands) are tow types of a line symmetric and an asymmetric shape. The line symmetric shape (corresponding to center elongation and edge elongation) is corrected by a work roll bending force and the asymmetric shape (corresponding to one side elongation) is corrected by a leveling amount. A work roll bending force and a leaving amount are corrected by finding both correction amounts corresponding to a line symmetric shape and an asymmetric shape based on outputs from shape detectors installed between stands. Thus, the shape between stands is improved and the easiness for sheet passing is drastically improved.

Title: Waveform generation circuit
Inventor: KOYANAGI NOBUO
IPC: H03K3/02
Filed: 1994-01-18
Abstract: PURPOSE:To oscillate an.exact trigger burst which is capable of steadily holding the initial state and the state at the time of a termination of a rectangular wave and holding the states at a low level, and is not affected by ringings, etc., by using a comparator with a radio function and controlling a circuit by using a trigger control circuit. CONSTITUTION:When a trigger signal is inputted in a trigger control circuit 60, the signal is synchronized by a clock CLK and a trigger/gate control signal EN is raised. By the rise of the first clock CLK after the signal EN becomes 'H', the first address is integrated to a latch circuit 12. Subsequently, every time the clock CLK is inputted, an address is integrated. By the address generated in this way, waveform data k read from a waveform memory 20 and the data are outputted as an analog waveform via a D/A converter 30 and a filter 40. At this stage, a trigger control circuit 60 makes a control signal LE to be imparted to a comparator 50 into 'L' at the same time of the generation of the first address. As a result, a rectangular wave is outputted from a comparator.

Abstract: PURPOSE: To automate the purification of a filter through a simple means while reducing the cost by providing a pickup probe comprising a heat insulator interposed between an inner tube to be heated for introducing a gas and an outer mantle to be cooled. CONSTITUTION: Tubular part 3 of a filter is formed as an extended part having diameter enlarged coaxially with the inner tube 4 of a pickup probe 1 and provided with an end side coupling flange 10 for supporting a filter cartridge 6 at a removable filter bottom part 8. The bottom part 8 provides an air supply nozzle having an opening to be coupled with an annular groove 12 which can be coupled with an air supply pipe 16 supplying the air into the annular space between the tubular part 3 and cartridge 6. Since dust in that space is blown back into a reaction case when the air is blown through the annular space between the tubular part 3 and cartridge 6, the filter 6 is cleaned automatically by arranging the tubular extended part 3 of inner tube 4 coaxially with the probe 1.  Since such air flow is present surely in the air supply nozzle within the range of bottom part 8, no residue is left in the annular space which is thereby cleaned.
