Abstract: PURPOSE:To alter alignment in the face-to-rear direction easily by selecting the blow direction through mounting of only an air nozzle without replacement of parts or change of parts feeder when the alignment direction must be changed. CONSTITUTION:Semiconductor devices 100 are advanced in the direction of arrow by vibrating a parts feeder 200 while they are put in alignment on a raceway 201. The raceway 201 includes a face-to-rear judging part 202 which makes judgement, if the surface concerned is face or rear, on the way of advancing in the direction of arrow, and the semiconductor devices 100 whose specified surfaces are put on a side, are exhausted. Changeover of the air blow to nozzles 203, 204 provides alignment to one side. The surface 102 in the illustration is the specified side, and the air is blown to 100 in a to drop off in the X direction while the air is not blown to 100 to cause remaining in b to be exhausted as it is. The air is blown at normal times from a nozzle of 204.

Abstract: PURPOSE:To provide the interruption control system of the on-chip microprocessor. CONSTITUTION:A 1st interruption control circuit 121 judges whether or not an external interruption request signal 131 can be accepted by a 1st processor 111 and sends it to a 2nd processor 112 and a 2nd interruption control circuit 122 when not, but the 1st processor 111 processes it when the signal can be accepted, so the signal is not propagated to 2nd and succeeding processors 112 and 113.

Title: Waveform equarizing system of magnetic recording or reproducing system
Inventor: MITA SEIICHI
IPC: H04L25/03
Filed: 1983-02-07
Abstract: PURPOSE:To improve greatly the code error factor by equalizing selectively the wave to be interfered and making use of a fact that a waveform having large interference between codes and a normal waveform within the original allowable value are mixed into a time variance component in terms of time. CONSTITUTION:Waveform compensating circuits 2 and 4 use transversal filters containing delay lines 6 and 7 or 17 and 18, attenuators 8 and 9 or 19 and 20, and an adder 10 or 21. The amount of compensation of the frequency characteristics is decided from the amounts of delay and addition. An amplitude controller 3 consists of buffer amplifiers 12 and 13, diodes 14 and 15, and attenuators 11 and 16. A variable attenuator 11 controls the amplitude applied to a pair of diodes, and therefore the threshold level can be set freely. For instance, the output voltage of the amplifier 12 is set at 2V and therefore it is possible to give compensation to a signal having the total reduction of amplitude by 6dB as long as a Schottky diode is used. As a result, the code error factor can be greatly improved.

Filed: 1998-01-15
Abstract: PROBLEM TO BE SOLVED: To improve the quality of a read image by pressing a document to contact glass while bringing the document in proper contact by a pressure plate. SOLUTION: The pressure plate 14 of the document reader is formed in three-layered structure by adhering a pressure plate main body 15, sponge 16, and a white sheet plate 17 with both-sided adhesive sheets 18 and 19, and the pressure plate main body 15 and sponge 16 have only their peripheral parts adhered with the both-sided adhesive tape 18 and do not have their center parts adhered. Therefore, even if the pressure plate main body 15 curves, the sponge 16 does not follow up the curvature of the pressure plate main body 15 and the nonadhesion part of the center part absorbs the curvature of the pressure plate main body 15.  Consequently, even if the pressure plate main body 15 curves, a document is set on the contact glass and pressed to the contact glass by the pressure plate 14, so that the document can be brought into contact with the top surface of the contact glass by the white sheet plate 17 without forming any gap.

In idle vibration, the shake orifice 50 is clogged so that the electric viscous fluid 28 does not flow in the shake orifice 50. The electric viscous fluid 28 flows in the idle orifice 52 and piezo-resonates therein to lower a movable spring and absorb the idle vibration.

Abstract: PURPOSE:To improve economic efficiency and markedly improve the working performace by constituting a sealed structure body from shape memory material and other materials and joining the shape memory material and other materials by a sealing joint means. CONSTITUTION:A heat pipe 1 is constituted of a shape memory alloy part (a) and other parts (b), and welding-jointed at the (c) part. When the heat pipe on the A side is heated by the high-temperature fluid 6, the heat pipe on the B side is heated, and the shape memory effect of the shape memory alloy acts to deform the shape memory alloy part (a) to the form shown by the dotted line 5. When the heat pipe on the B side is cooled by the low-temperature fluid 6, the form is restored to a linear form before deformation by the shape memory effect. Through the repetition of the heating by the high-temperature fluid 6 and the cooling by the low-temperature fluid 7, a supporting metal fitting 4 moves in reciprocation. Therefore, the economic efficiency can be improved, and the working performance can be markedly improved.
