Title: Variable inductor
Inventor: ISHIMA TSUTOMU
IPC: H01F21/04
Filed: 1989-11-27
Abstract: PURPOSE:To allow inductance to continuously change, and to use a variable inductor for high-frequency large currents owing to its noncontact type by varying the relative positions of two solenoid coils. CONSTITUTION:When high-frequency voltage is applied between terminals 4, 5, magnetic fields in the opposite direction are generated in an external solenoid coil 1 and an internal solenoid coil 2 respectively. Both magnetic fields cancel each other with the approach of both solenoid coils 1, 2, and the degree of denying is maximized when the internal solenoid coil 2 is inserted completely to the external solenoid coil 1. When the magnetic fields are canceled and reduced, inductance is also diminished because magnetic flux is also decreased. Consequently, the relative locations of the external solenoid coil 1 and the internal solenoid coil 2 are changed, thus freely altering inductance. Accordingly, large currents can be made to flow in a noncontact manner, thus continuously varying inductance.

Title: Feed lifting lock stich sewing machine and method for preventing puckering in the same
Inventor: OISHI NOBUO
IPC: D05B27/06
Filed: 1988-11-30
Abstract: PURPOSE:To prevent failure in sewing such as puckering and uneven material feeding when sewing thin material by arranging upper and lower feed dogs in such a manner that their sandwiching faces may sandwich the material therebetween at positions past the dropping point of a needle along the direction of feeding of material, and providing lifting means for maintaining the rising position of a presser until a tightening force acts on sewing thread. CONSTITUTION:An upper feed dog 5 falls down to hold material W, at which time a presser 4 is lifted by lifting means 45 in conjunction with lifting of the upper feed dog 5 by a lower feed dog 6, so that the material W is not substantially pressed. Besides, a tightening force begins acting on sewing thread from that point G of time which is just before a balance reaches is upper dead point, but, while the upper and lower feed dogs 5, 6 sandwich the material W therebetween, the presser 4 maintains its rising position even under the action of the tightening force; the tightening force that may cause the material to pucker and deform will therefore not act on the material. The upper and lower feed dogs 5, 6 are both arranged past the dropping point P of a needle along the direction of feeding of material in order to prevent uneven feeding between upper and lower materials by feeding the sewed material W in a pulling manner, and also to prevent the material W from puckering when a seam alreadly formed is pulled back by the tightening force exerted by the sewing thread.

Title: Antiskid control device
Inventor: KADOSAKI SHIROU
IPC: B60T8/66
Filed: 1992-10-16
Abstract: PURPOSE:To heighten the hydaulic pressure control accuracy of an antiskid control device for increasing/reducing brake cylinder pressure by both normal/ reverse rotation of an electric motor. CONSTITUTION:In the case of being set to a pressure boosting mode and the slip state quantity being on the increase, the preset slip state quantity Ws is successively made the maximum slip state quantity Wsp (S74), and 40% of the maximum slip state quantity Wsp is successively made the threshold Wsd (S75). In the case of the slip state quantity Ws being decreased to become the threshold Wsd or less (S76), the changeover to a pressure boosting braking hold mode is made to perform dynamic braking (S78). The normal rotation of a motor is thereby suppressed desirably, and a pressure boosting gradient can be eased to avoid excessive boosting and to improve hydraulic pressure control accuracy. Also, since the threshold Wsd is determined according to the maximum slip state quantity Wsp (the maximum rotating speed of a motor), the rotation of the motor can be suppressed according to inertia.

Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To digitally transmit compressed and uncompressed decoded data through a digital output port of a common constitution by forcibly selecting a fixed end A of a switch when a designated signal exists even in DVD. SOLUTION: After being put in readiness for reproducing, a CPU 8 outputs a control signal to change over a switch 5 to the side of a fixed end A. When the CPU receives a disk discrimination signal from a data decoding circuit 3 and the kind of the disk is recognized as a CD, a play is started just as it is. A linear PCM signal is inputted to an encoder circuit 6 from the CD and outputs self-synchronized serial data from an output port 7. On the other hand, a DVD is recognized, when DVD is not indicated and a designated signal is not inputted, a switch 5 is changed over to B side of the end and a play is started and uncompressed decoded data are outputted from an output port 7.  On the other hand, when a designated signal exists, compressed decoded data are inputted to the circuit 6 without changing over the switch 5 to its fixed end B, and serial data which have self-synchronized the compressed decoded data are outputted from the output port 7.

IPC: G08B25/04
Filed: 1989-11-27
Abstract: PURPOSE:To securely make a warning on the side of a centralized control board even if a power failure occurs on the side of a house information board by connecting a sensor line connection terminal to a warning signal line connection terminal by a signal connecting means when the internal power source of the house information board enters a failure state. CONSTITUTION:When the internal power source VCC of the house information board 2 enters the failure state, none of a warning detecting circuit 2a, a warn ing shift means 2b, and the signal connecting means 2c operates. Therefore, the relay RY 2 of the signal connecting means 2c is not driven and relay contacts ry21 and ry22 are switched to their (a)-contact sides to make connections between sensor line connection terminals TS and TS', and warning signal line connection terminals T1 and T1'. If one sensor S generates a warn ing, sensor lines lS and lS are short-circuited. Consequently, a warning signal is detected directly on the side of the centralized monitor board 1 through a warning signal line l where the warning signal line connection terminals T1 and T1' are short-circuited and the warning is generated.
