Patent JP-H10190224-A (JP)
Title: Multilayer printed wiring board and its manufacture
Inventor: HIRAMATSU YASUJI
IPC: H05K3/38
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To maintain adhesion between a via hole and a lower-layer conductor circuit and prevent cracking in an interlayer insulating layer during heat cycle, by forming the via hole from an electroless plating film and an electrolytic plating film, and forming a roughened layer on the surface of an area where the lower-conductor circuit is in contact with the via hole. SOLUTION: A via hole is formed of an electrolytic plating film 4 and an electroless plating film 3; the electroless plating film 3 is formed in an inner layer and the electrolytic plating film 4 is formed in an outer layer. The electrolytic plating film 4 is softer and more malleable than the electroless plating film 3. If a substrate warps during a heat cycle, therefore, the via hole is capable of following variation in the dimensions of a layer resin insulating layer 6. Further, since the inner portion of the via hole is formed of the harder electroless plating film 3 and the electroless plating film 3 is brought into tight contact with a lower-layer conductor circuit 2 through a roughening layer 5, the electroless plating film 3 does not strip from the lower-layer conductor circuit 2 during a heat cycle.

Filed: 1991-12-28
Abstract: PURPOSE:To prevent the degradation of the performance reading information in a disk storage medium by transferring an optical head device and detecting the fluctuation of a load at the time of transferring and storing the detected load in a memory. CONSTITUTION:The driving current value of a motor 18 is measured while moving a head carrier 12 at equal intervals from the innermost circumference to the outermost circumference in the radial direction of a disk storage medium 17 and the data is stored in the memory 21.

Title: Image transmitter
Inventor: MUTO SATOSHI
IPC: H04N1/32
Filed: 1999-12-17
Abstract: PROBLEM TO BE SOLVED: To provide an image transmitter such as a facsimile terminal that can reduce the communication time by avoiding communication with reception destination terminals at a lower communication rate than a substantial communication capability of the reception destination terminals in the relay broadcasting. SOLUTION: The image transmitter acting like a relay broadcasting transmitter compares a communication speed, a compression method and a resolution conducted with respect to a transmission source with communication results of the reception destinations and compares the communication speed, the compression method and the resolution conducted with respect to the transmission source with contents registered in the reception destinations (S6, S7) and the image transmitter transmits data to the reception destinations in parallel with reception of data from the transmission source.  On the occurrence of the case where the transmitter has to make transmission at a lower communication speed than the substantial communication capability of the reception destinations (NO in S9), the transmitter receives image data from the transmission source and then transmits the data to the reception destinations without the transmission of data in parallel with the reception (S11). Thus, it is avoided that the transmitter makes communication with the reception destinations at a lower communication speed than the substantial communication capability of the reception destinations.

Abstract: PURPOSE:To execute an adequate initialization stage by detecting the temp. of a fixing device at the time of turning on a power source, estimating an operation history in accordance with this temp. and controlling the initialization stage in accordance with this estimation. CONSTITUTION:The surface temp. of a pressurizing roller 25a of the fixing device 23 is first detected by a temp. detecting means 101 when the power source is turned on in order to start a device which is once in a stop state.

Title: Driving device
Inventor: KIHARA NOBUTOSHI
IPC: F16H15/04
Filed: 1991-12-28
Abstract: PURPOSE:To drive a driven object by manual rotation and so on by pushing a frictional part against a rotary body with a prescribed push-pressing force, receiving a driving force from the rotary body, and reducing a frictional force by means of a centrifugal force changing according to rotational speed. CONSTITUTION:When a frictional part 38 is pushed against a rotary body proper 18B by means of a spring 36, a frictional force between the rotary body proper 18B and the frictional part 38 is increased, so that the rotary body proper 18B can transmit a rotating/driving force to a rotary shaft 22J. When rotational speed of a body 20 to be driven in rotation is incresed, a centrifugal force applied to support members 26A and 26B is also incresed, and since a slip governor 20 has such a constitution that a pyramid 37 equivalent to a mass of the support members 26A and 26B is arranged on the tip of the spring 36, a push-pressing force of the spring 36 is also reduced, and the frictional force between the frictional part 38 and the rotary body proper 18B is also reduced. Accordingly, the rotating/driving force being transmitted to the rotary shaft 22J is also reduced, and the rotational speed of the body 20 to be driven in rotation can be decreased. Thereby, a driven object can be driven at constant rotational speed even by manual rotation and so on.
