Filed: 1978-03-20
Abstract: PURPOSE: To eliminate the need for work of removing an oleo-wick, and to obtain stable bearing performance, by arranging this device so that the oleo-wick not be filled up to the space of an end portion at the shaft inserting hole side of a bearing support, in the bearing device that the oleo-wick is charged to a bearing portion.  
     CONSTITUTION: A circular arched projection portion 19 is formed to an end portion at the shaft inserting hole side of a notch plane portion 13 of a bearing 8. The dimensions of the projection portion 19 are set so that a minute clearance g that only oil can pass be shaped between an outer circumferential surface of the projection 19 and an inner circumferential surface of a bearing support 3 when the bearing 8 is inserted into the bearing support 3. Consequently, an end portion at the shaft inserting hole side of an oil path 15 is partitioned from the space C of an end portion at the shaft inserting hole side of the bearing support 3 besides the minute clearance g. Thus, an oleo-wick 12 can be filled only to the oil path 15 if an enclosing door 16 is fitted to an opening end portion at the bearing inserting side of the bearing  support 3 and the oleo-wick 12 is injected from the inflow hole 18.

Title: Capacitor discharge type ignition device
Inventor: SOTOZAKI MORIYOSHI
IPC: F02P3/08
Filed: 1986-02-14
Abstract: PURPOSE:To stabilize idling by delaying ignition in a low rotation range, by a method wherein a parallel circuit of a capacitor and a resistor is connected between the gate and the cathode of a semiconductor opening and closing element. CONSTITUTION:By means of an output in a positive direction from a generating coil 10, a capacitor 12 is charged, and by means of a subsequent generated output in a negative direction, a thyristor 17 is energized to suddenly feed charge to an ignition coil 13. In which case, a parallel circuit of a capacitor 22 and a resistor 23 is connected between the gate and the cathode of the thyristor 17. This constitution causes branching of a part of a current, serving to energize the thyristor 17, to the capacitor 20 to charge it. Thus, in a region in which the number of revolutions of an engine is low, with the increase in the number of revolutions, a current introduced to the capacitor 22 is decreased, and the energizing timing of the thyristor 17 is expedited, resulting in gradual execution of a lead angle.

Title: Control method for image sensor of optical device
Inventor: HIDESHIMA TAKAHIRO
IPC: H04N5/217
Filed: 1987-02-13
Abstract: PURPOSE:To keep a light exposure constant against the fluctuation of the power source frequency by supervising time between two transfer pulses, outputted before and after a synchronizing signal, which synchronizes with the change of a quantity of light, i.e., the time from the transfer pulse to be the starting point of an effective storage time till the synchronizing signal. CONSTITUTION:The transfer pulse B is successively outputted at every standard time l, while being synchronizing with the zero cross point of an alternating power source, i.e., with the synchronizing signal A, and a transfer pulse interval between the two transfer pulses before and after the synchronizing signal A is assumed to be the effec tive storage time (m). As for a latch 78, when the signal A is outputted on the halfway of the time (m), the count number N' of a counter 74 at that time fluctuates as well. A subtracter 80 supervises the time DELTAt from the transfer pulse B to be the starting point of the time (m) till the signal A, by using this number N'. The count number DELTAN to show the time DELTAt is inputted to the subtracter 82, and the count number N(x) to show the new standard time (x) is obtained. This N(x) is set through a change-over switch 72. Accordingly, the count number N(x) is set so that a sum together with DELTAN is always equal to the number Nm of the time (m). Accordingly, even when the power source frequency fluctuates, the time m=DELTAt+x does not fluctuate.

IPC: H05K1/09
Filed: 1992-02-19
Abstract: PURPOSE:To prevent cutting of a conductive pattern at contact points by forming individual protective layers having specified thickness on the top surface of the contact points between a first member substance and a second member substance, which have different expansion coefficient respectively, and by laminating a conductive pattern on the protective layers. CONSTITUTION:A protective layer 4 is laminated on the surface 2B of a contact 5 between a via 1A as a first member material 1 and a ceramic substrate 2A as a second member materials 2 which has different expansion coefficient from the first member material 1. Then, a conductive pattern 3 is laminated on the upper layer of the protective layer 4. If difference in level is generated at the contact between the first member material 1 and the second member material 2, by expansion or shrinkage due to difference of expansion coefficient, and if difference in level is generated on the surface 2B of the ceramic substrate 2A, the difference in level shall be absorbed by leveling up the bonded surface of the protective layer 4 with the conductive pattern 3. Therefore, even if the via 1A is protruded from the surface 2B due to heating of the ceramic substrate 2A, the conductive pattern 3 is prevented from being cut, and there will be no fault of wire breaking. As a result, reliability can be improved.

Abstract: PURPOSE: To sufficiently decrease the operation resistor of two terminal constant voltage circuit from small current area with a simple circuit.  
     CONSTITUTION: In Figure, the output voltage V 0  is expressed in equation 1 and it can be set to an arbitrary value by suitably selecting R 1 /R 2 . The circuit current I 0  is as in equation 2, by taking the emitter currents of Q 1 , Q 2  as IE 1 , IE 2  and the voltage between emitter and base as VBE 1 , VBE 2  respectively. The operating resistor r is expressed in equation 3 with re 1 =ΔVBE 1 /ΔIE 1 , re 2 =ΔVBE 2 /ΔIE 2  and re 1 ≪R 2 , re 2 ≪R 3 . Thus, the operating resistor r is re 1 /R 3  times conventional one, and since it is a reciprocal of the voltage gain of Q 1 , it can remarkably be reduced in comparison with conventional circuits.

Abstract: PURPOSE:To surely close an opening and closing valve after the venting of air is completed even at a place different in atmospheric pressure or even in a case entering sterilization treatment continuously by closing the opening and closing valve upon the reception of a signal showing a temp. value stable in the temp. change rate at the time of an air venting process detected by a temp. detection sensor within a set time. CONSTITUTION:When the air in a chamber 7 is vented, a control apparatus 29 opens an opening and closing valve 27 to turn a heater 9 ON. Water temp. rising by turning the heater 9 ON is monitored by the first temp. detection sensor 13. This monitoring is continued until boiling temp. stabilizing a temp. value and this temp. value is detected on the basis of the temp. change rate of water temp. Next, the temp. in the chamber 7 is monitored by the second temp. sensor 15 and the temp. of steam is detected on the basis of the temp. change rate. Air is excluded from the chamber 7 through an opening and closing valve 25 by generated steam pressure and the chamber 7 becomes a state filled with saturated steam under atmospheric pressure. The steam saturated state is kept as it is for a relatively short time in order to make said state more perfect and, thereafter, the opening and closing valve 25 is closed to bring the chamber 7 to a perfect hermetically closed state.
