Title: Blood component separating device and blood component separating method
Inventor: SUZUKI ATSUSHI
IPC: B04B11/02
Filed: 1994-05-23
Abstract: PURPOSE:To provide a highly accurate and safer blood component separating device by arranging an optical sensor to optically detect an interfacial position of a blood component in a centrifugal separator and a control means to control actuation of a pump according to a detecting signal from the optical sensor. CONSTITUTION:When a rotor 42 is rotated simultaneously with blood-collection, blood introduced in a centrifugal bowl 4 is separated into a plasma layer 31, a buffy coat layer 32 and a red blood cell layer 33 from an inner layer in this order in a passage of the rotor 42. An interfacial position between the buffy coat layer 32 and the plasma layer 31 at a moment when plasma in the rotor 42 overflows from an outflow port 44 is detected by an optical sensor 6. In this way, since an interface of a separated blood component is detected by the optical sensor 6, and the timing of finishing blood-collection or of starting return of blood is controlled according to the detection and the finish timing of returning blood is also controlled by a rotational quantity of a pump in a blood introducing line, higher degree control becomes possible.

Filed: 1989-05-26
Abstract: PURPOSE:To operate a 2-way counter at low speed and to reduce the power consumption by adding an M-stage 2-way counter with a few capacity of free- run type to a multi-value quantizing phase comparator. CONSTITUTION:The M-stage 2-way counter 1-6 counts up with an L level input and counts down with an H level input. In the case of overflow, a phase lead information pulse is sent to the 2-way counter 1-2 and in the case of occurrence of underflow, a phase lag information pulse is sent to the counter 1-2. The counter 2 counts up with a phase lead information pulse and sends a 1 pulse elimination control signal D to a pulse addition/elimination circuit 1-8 when the result of count reaches 2N. Simultaneously, the counter 1-2 is reset to N. Moreover, the counter 1-2 counts down with the phase lag information pulse and when the result reaches 0, a 1 pulses addition control signal I is sent to the circuit 1-8 to reset the counter 1-2 to N. Thus, the counter 1-2 is operated at low speed.

Title: Pressure hardening machining method for nut seat of bolt hole of light metal molded product
Inventor: FUJINO KIYOSHI
IPC: B24B39/02
Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To prevent the falling off of a nut seat caused by a bolt load having a large axial force by attaching a taper roller to the tip of a cantilever shaft and turning this while pressing this to the nut seat and hardening the nut seat. SOLUTION: When a taper roller 4 is contacted with a nut seat 3, the taper roller 4 is turned while applying a pressing force produced in a spring 13 to the nut seat 3. At this time, a contact pressure is produced in the surface of the nut seat 3, the nut seat 3 and the structure of a back surface for backing up the same are pressurized and then meticulous machining and hardening is performed. When the vertex C of a conical surface forming the nut seat 3 is made coincident with that of the conical surface of the taper roller 4, the taper roller 4 is turned while not slid in the surface of the nut seat 3 and thus little 'peeling' is produced even if a contact pressure is increased and thus large pressed hardening is performed.

Title: Semiconductor device
Inventor: SUGINO HIROYUKI
IPC: H01L21/66
Filed: 1989-05-26
Abstract: PURPOSE:To disqualify reliably a semiconductor chip having its broken end in a test for wafers and to shorten a test time to be spent for the chip having its broken end by a method wherein a testing wiring for connecting two testing pads provided on each semiconductor chip is arranged along the peripheries of the chip. CONSTITUTION:A testing wiring 20 for connecting two testing pads X and Y provided on a semiconductor chip is arranged on four peripheries 101 to 104 of the chip. At the time of test of a wafer, the two pads X and Y are first tested whether they are short-circuited or not. If the chip is a semiconductor chip having no break in its end, the short-circuit is detected because there is not the disconnection of the wiring 20. On the other hand, if there is a break in the chip, the short-circuit is not detected because the wiring 20 is disconnected and an existence of a break in the chip can be immediately judged. Thereby, the semiconductor chip having its broken end can be reliably disqualified and at the same time, a test time to be spent for the chip having its broken end can be shortened.

IPC: H01L21/302
Filed: 1989-05-26
Abstract: PURPOSE:To equalize the quality of wafers after etching process by a method wherein the output of high-frequency power is corrected corresponding to the self bias voltage induced when plasma is produced between both electrodes. CONSTITUTION:The title dryetching device is constituted so that the output from a high-frequency power supply 7 may be controlled to equalize a self bias voltage value outputted from a wave filter 21 with a set up value when a plasma 8 is turned into a state different from the set up value so as to vary the self bias voltage value from the set up value. Accordingly, even if the plasma state is changed to change the self bias voltage, the energy of ion plasma hitting a wafer can be maintained in a constant value. Through these procedures, respective wafers can be etched evenly without changing the etching state in every wafer thereby augmenting the quality of the wafer etching process.

Abstract: PURPOSE:To eliminate the necessity of a high precision process so as to reduce the manufacturing cost by moving a slit plate of a rocker arm to a position where it engages with a lost motion mechanism with the use of an engagement change-over means, and by providing means for releasing the engagement between the rocker arm and a free cam follower, etc. CONSTITUTION:During, for example, a low speed operation of an engine, a rocker arm 2 is swung in association with a low speed cam 5 so as to open and close an intake valve 1. At this time, no hydraulic oil is fed into a hydraulic chamber 16, and accordingly, a slit plate 9 is held at a position as shown by means of a return spring 14. That is, a slit 9A comes off from a stepped part 4C on a leg part 4B of a free cam follower 4 which is engaged therewith at a position where it depresses an upper spring retainer 8A in a lost motion mechanism 8 by a degree corresponding to a difference in lift between high and low speed cams 6, 5. Accordingly, it is possible to prevent the motion of the rocker arm 2 from being hindered even though an input is exerted to the high speed cam 6 since only a lost motion spring 8C is deformed.

Abstract: PURPOSE:To reduce a stress added to the switching element of a resonance type inverter circuit at the time of inputting a power source in a discharge lamp lighting device in which the resonance type inverter circuit is combined with a low frequency circuit to energize a discharge lamp by a rectangular wave AC output. CONSTITUTION:The output of a DC power source 1 is converted into a high frequency by a resonance type inverter circuit 2, rectified by a rectifying circuit 3, and converted into a low frequency rectangular wave AC output by a low frequency circuit 5 to light a discharge lamp 6.
