Title: Ceramic laminated capacitor element and manufacture thereof
Inventor: YOKOYA YOICHIRO
IPC: H01G4/008
Filed: 1988-10-26
Abstract: PURPOSE:To obtain a ceramic laminated capacity element which is hard to form the secondary phase by dissipating at least one type of oxide element of Nb and Ta from an oxide particle contained in an inner electrode layer below 1300 deg.C into a dielectric using a powder in a specific particle diameter for a titanium acid barium powder.

IPC: H03K23/00
Filed: 1987-10-26
Abstract: PURPOSE:To continue clock generation when the supply of a reference clock signal is interrupted by providing a reset signal generating means and a clock generation circuit and generating a clock in the clock generation circuit based on a reset signal generated by frequency-dividing the input clock signal. CONSTITUTION:If a fault takes place in the supply of the external reference clock signal 215 and the reference clock signal 215 is fixed to a high level, a high level signal is always supplied to a reset terminal R of a counter 211 and the count of counters 211, 212 is stopped. Thus, the generation of the reset signal 217 is stopped. When no reset signal 217 is outputted from a D-FF 216, the reset of counting in the counters 221, 222 is not applied. However, when the input clock signals 213 is fed normally to the counters 221, 222, the counting of the counters 221, 222 is continued. Thus, the generation of the clock signals 223, 224 is continued.

Title: Automatic document conveying device and its control method
Inventor: KUBO HIROSHI
IPC: G03G21/14
Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To prevent damage of a device when a bottom plate is detected abnormal by setting a moving amount of a document lifting means based on the detected information by a document stacking height detecting means, and driving a document lift driving means by the moving amount. SOLUTION: By placing documents, a document set filler 87 removes from a document set sensor 21 to turn on the sensor. Using displacement of a slit of an encoder portion 89 of the document set filler 87, a control portion determines stacked height of the documents 5 from displacement amount of the encoder using a signal of a stacked height sensor 88, calculates moving amount of a bottom plate 7, and drives and controls a bottom plate lifting motor based on the driving pulse so that the bottom plate 7 rises by the moving amount. Because a calling roller 8 drops by rotation of a vertical cam 80 through the document set sensor 21, the bottom plate 7 rises in a state that the upper surface of the documents 5 abuts to the calling roller 8.  When a paper-feed proper position sensor 27 does not detect a paper-feed proper position filler 82 even if the bottom lifting motor is driven by number or pulses corresponding to the lift moving amount, the motor is stopped.
