Title: Synchronous rectifying converter
Inventor: TANAKA KIICHI
IPC: H03K17/08
Filed: 1994-12-09
Abstract: PURPOSE: To obtain a synchronous rectifying converter of which the synchronous rectifying FET and commutation FET are not operated by a reverse current from a DC power source when the converter is used by connecting the converter in parallel with the DC power source. CONSTITUTION: A synchronous rectifying converter applies an input DC voltage across the primary winding of a transformer after converting the voltage into a rectangular wave pulse voltage by means of a semiconductor switch 2 and rectifies and smoothes the voltage pulse fetched from the secondary winding of the transformer by means of a synchronous rectifying FET 4, a commutation FET 5, a choke coil 6, a capacitor 7, etc. The converter is constituted so that the FET 4 cannot be operated by an external DC power source 12 connected in parallel with the coverter. Therefore, a switch circuit 23 which detects the voltage drop across the source and drain of the FET 4 and, when the detected voltage value becomes higher than a prescribed value, sets the commutation FET 5 to an operating state is provided.

Abstract: PURPOSE:To obtain the ferroelectric piezoelectric porcelain composition wherein the characteristics such as composition, specific inductive capacity and coupling coefficient in the diametral direction are specified by utilizing Pb3O4 as the raw material of Pb atom in the case of producing the ferroelectric piezoelectric porcelain composition incorporating Pb atom in one part. CONSTITUTION:The ferroelectric piezoelectric porcelain composition (e.g. PbZrO3-PbTiO3-based ferroelectric piezoelectric porcelain composition) incorporating Pb atom in one part is produced by utilizing Pb3O4 as the raw material of Pb atom. Thereby the conventional ferroelectric piezoelectric porcelain composition is produced by utilizing PbO as the raw material of Pb atom and varied in the characteristic value such as composition, specific inductive capacity, coupling coefficient in the diametral direction and voltage output coefficient. Even when Pb3O4 is left to stand in the air, effect of moisture, etc., is not almost caused. Since Pb3O4 is utilized as the raw material of Pb atom, the ferroelectric piezoelectric porcelain composition having the specified characteristics is obtained even when Pb3O4 of a fresh lot or Pb3O4 of an old lot after preservation is utilized.

When that course is prescribed, a trajectory section corresponding to this course is extracted and the trajectory section reservation table 12 is searched for to confirm the presence or absence of another previous corresponding reserve. When no reserve exists in regard to any trajectory section, an availability instruction concerning the course is outputted from the course reservation by-reference examination means 21 while an alteration instruction and a course reservation instruction as prescribed in a corresponding point are outputted from the point control means 23.

Title: Communication equipment in token ring
Inventor: NISHINO KEITARO
IPC: H04L12/42
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To reduce time loss in which a token goes around a token ring by providing plural LAN controlling parts for receiving a token and for transmitting and receiving a telegraphic message in one node, and successively transferring the token by the LAN controlling parts in one node. SOLUTION: When a request for the transmission of plural telegraphic messages in a host device 11 is present at the same time, a first LAN controlling part 22-1 receives a token, and transmits one telegraphic message. Then this token is transferred to a second LAN controlling part 22-2, and when the token is received by the LAN controlling part 22-2, another telegraphic message is transmitted from this LAN controlling part 22-2. Moreover, the token is transferred to a third LAN controlling part 22-3, and another telegraphic message is transmitted from this LAN controlling part 22-3. Afterwards, this processing is repeated successively, so that each telegraphic message can be transmitted from each LAN controlling part. As a result, the telegraphic messages generated at the same time in the host device 11 can be continuously transmitted only by one token.

Title: Rotation drive device
Inventor: SATO ICHIRO
IPC: F16H1/28
Filed: 1989-12-22
Abstract: PURPOSE:To obtain large output by small input so as to make a device compact by mounting an inner gear having small diameter, and an output gear, and a static gear having a large diameter on a spindle rotatingly and using reaction force from the static gear as an input means. CONSTITUTION:Rotation driving force of a crank arm 2 is transmitted to an inner gear 4 via a support wheel, and the inner gear 4 rotates with a spindle 1 as axis and makes an outer gear 9 rotate at high speed. Rotation of the outer gear 9 is transmitted to an outer gear 11 via an outer gear 10. Although the outer gear 11 tries to rotate a static gear 17 with which it engages, the static gear 17 won't move. It revolves on the outer periphery of an inner gear 17 while it rotates due to the reaction. At this time, all the rotation energy which the outer gear has is returned in the static gear 17. Consequently, the rotating force is combined with the rotating force which is transmitted from the outer gear 10 and increases, and the increased rotating force is transmitted to an output gear 15. Also, since a part of rotating force which is returned to the outer gear 11 is transmitted reversely, the burden of input is reduced.

Filed: 1994-12-16
Abstract: PURPOSE: To make it possible to rapidly focus at a layer desired to be moved by accelerating an objective lens up to rising of an S-shaped curve of a focus error signal of the desired layer. CONSTITUTION: A focus OPEN signal turns to a high level, a switch 18 selects a phase compensation circuit 17 and a focus servo loop turns on.
