Title: Vertical type silicon thermopile and manufacture thereof
Inventor: SAKAMOTO HIKARI
IPC: G01J5/02
Filed: 1989-03-24
Abstract: PURPOSE:To make it possible to obtain a thermopile of a three-dimensional structure wherein the electromotive force of thermocouples is large and which does not require a large area even when a large number of thermocouples are disposed therein, by fitting an electromagnetic wave absorber on the hot contact side with an insulative layer interlaid. CONSTITUTION:The end faces on one side of P-type layers 21, 22,... and N-type layers 31, 32,..., e.g. the end faces thereof connected by metal layers 52, 53,... constitute the hot contact side, while the end faces connected by metal layers 61, 62,... on the other side constitute the cold contact side. On the hot contact side, an electromagnetic wave absorber 70 is formed with an insulative layer interlaid. In a thermopile thus constructed, the temperature of the electromagnetic wave absorber 70 rises (falls) due to an electromagnetic wave entering the absorber and the temperature of a hot contact of a thermocouple located in the vicinity of the absorber rises higher (falls lower) than that on the cold contact side. Accordingly, a temperature difference occurs between the hot contact and the cold contact of the thermocouple and a thermoelectromotive force is generated by a Seebeck effect. According to this constitution, the thermopile of a three-dimensional structure is obtained and this is effective for a one-dimensional or two-dimensional sensor of high resolution.

Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To eliminate the oscillation of a control system even if an excess command value to saturate a current amplifier is input by providing means for feeding back the deviation signal of a current command value from the actual motor current value to a position or current command value. SOLUTION: A route for feeding back the deviation voltage Vd output from a current amplifier 14 to a command value via an A-D converter 19 and a digital filter 20 is provided. Such a feed-back loop is provided, and hence even if an excess command value for causing an oscillation is given, the voltage Vd is fed back to the command value side. Accordingly, the gradient of the command value is corrected to the level for inhibiting the saturation of the amplifier. As a result, a table can follow up the command value without oscillation. Therefore, a table controller having extremely high reliability can be obtained.

Filed: 1980-06-03
Abstract: PURPOSE: To automatically deal with misfeeding in the inerior of an automatic deposit machine or the like and feed notes normally without returning a sheaf of  notes to an inlet each time misfeeding is caused.  
     CONSTITUTION: When misfeeding is caused, a lower take-in belt 2', a feed roller 4, and a separating roller 5 are reversed with an upper take-in belt 2 on the rise, and a sheaf of notes are once retired into a waiting chamber 3. When sensors S4, S4' detect the tail edge of the note, a motor rotates and only one note at the lower side can be fed out by rotation of the take-in belt 2', the feed roller 4 and the separating roller 5. Thus, at least the note to be fed is adapted to approach from the rear and pass a sensor position S2 with force, so that even if the leading edge of the note again gets caught in the apparatus, the note can pass as it is and the note once  caught in the apparatus gets loose to be fed normally.
