Title: Motor-driven fan
Inventor: KATO KIMINORI
IPC: F04D29/66
Filed: 1985-04-05
Abstract: PURPOSE:To decrease the noise, by forming small holes along the shaft's direction, in the diffuser of air guide of a centrifugal fan. CONSTITUTION:The diffuser 19 of air guide 17 of a centrifugal fan and the casing 14 of this fan are brought in contact with each other, at almost the middle part between the diffuser 19 and a return passage 21. Grooves 22' are formed along the shaft's direction, in the diffuser 19 of the air guide 17, and small holes 22 are shaped by said grooves 22' and the casing 14. Consequently, NZ (the product of the number of vanes of the impeller and the rotational speed) noise generated by the motor-driven fan can be decreased, because the NZ noise is absorbed by said small holes 22, and the constitution of this fan can be simplified.

Title: Method of positioning parts
Inventor: TAKESHITA SHIYUUJI
IPC: H01L21/68
Filed: 1979-06-11
Abstract: PURPOSE:To perform automatic positioning with high accuracy, by moving the lead of an IC or the like and the bonding pad of a printed circuit board relatively to each other to minimize the total quantity of reflected light from both the relatively moved members in an apparatus for positioning the lead on the bonding pad. CONSTITUTION:The surface of the bonding pad 4 of a printed circuit board and that of the lead 3 of an element are plated so that the light reflectivity of the plated surfaces is higher than that of the surface of the printed circuit board. When the pad and the lead are overlapped with each other, the quantity of reflected light is minimum. The total quantity of reflected light is measured in an image pickup range by a sensor 1. The measured signal is A/D-converted and then applied to a micro-processor 12. This processor controls a driving circuit 11 to minimize the quantity of reflected light. At that time, the printed circuit board 5 on a table 6 is moved so that the circuit board is accurately positioned. When the quantity of reflected light remains minimum as shown by a line A, equipment is controlled to plate the middle point (a) of the line A in a proper position. The lead and the pad can be overlapped with each other in a position deviated by a half pitch from a position corresponding to the maximum quantity of light.

Title: Semiconductor memory
Inventor: MAKI KAZUHIKO
IPC: G11C11/407
Filed: 1995-03-30
Abstract: PURPOSE: To reduce power consumption in synchronous semiconductor memory. CONSTITUTION: If an externally provided control signal RAME 1 has level '1', a PMOS 8 is turned ON when a precharge signal ϕbecomes '1' thus precharging a bit line BL. For example, a '0' data held in a RAM cell 1 connected with a selected word line WL1 is read out to the bit line BL which is thereby discharged. If the signal RAME is '0', the PMOS 7 is not turned ON even if the precharge signal ϕ becomes '1' and the word line WL1 is not discharged even if it is selected. Current consumption on the bit line BL can be reduced by sustaining the signal RAME at '1' except when it is required to be '0'.

Abstract: PURPOSE:To determine the position of the wire slot in a core correctly, by providing a cutout portion in the flange of the core, and making the mounting to and dismounting from a winding machine easy. CONSTITUTION:A hole 5b of a flange 1c of a ferrite core 1 and a hole 6 of a main core portion 1a are coupled with shafts 7a and 7b of a stepped guide pin 7 of a jig 10, respectively. A cutout portion 3 for positioning the flange 1c is coupled with a pin 9. The shaft 7a is embeded in the thickness of the flange 1c and the pin 9 is also embeded in the thickness of the flange 1c.

Title: Priority circuit in deck power supply
Inventor: HASHIMOTO ATSUMI
IPC: H04B1/20
Filed: 1983-04-25
Abstract: PURPOSE:To flow only a small current to the 2nd power supply line by connecting the 2nd power supply line connected to the 1st power supply line connected directly to a common power supply and to the common power supply via a stereo deck circuit to a radio circuit to flow a large current only to the 1st power supply line. CONSTITUTION:In turning on a switch SW2, a transistor (TR)Q2 is turned on since the base is forward-biased by a diode D3. Since the power supply voltage is applied to a terminal T5 via the 1st line l1, a tuner circuit 5 is operated. Simultaneously, since a TRQ3 is turned on because the base is forward-biased via a diode D2, a TRQ4 is turned on because of its base current flowing. Since the power supply voltage is applied to a terminal T6 via the 2nd line l2 comprising the terminal T3, the emitter of the TRQ4 and the collector in this way, an amplifier circuit 6 is also activated. Although a switch SW2 of the car stereo deck 2 is thrown to the contact A automatically, no effect is given because the terminal T1 is idle.

IPC: B21C37/08
Filed: 1983-04-28
Abstract: PURPOSE:To manufacture an UOE-system steel pipe by a small press duty by U- forming a blank plate having properly bent ends and further, O-forming it by regulating an acting angle of forming force within a range of giving no circumferential compression, before welding, expanding, and straightening a formed plate. CONSTITUTION:A blank plate 10 is U-formed after subjecting the ends of plate 10 to an end bending by regulating a bending radius (rc) at the end parts within an allowable range of peaking between the end parts of plate 10 at the time of O-forming, or regulating it preferably to the degree of (rc)/R=0.62-0.75 with respect to the radius R of a desired steel pipe. Next, a welding is performed by restricting the O-forming within a range, where an acting angle of forming force with respect to the plate 10 is >=-45 deg. and gives no circumferential compression. Next, the out of roundness of a welded pipe is straightened while expanding it with a small expanding rate to obtain a steel pipe having a desired radius, thus a duty of forming press necessary for performing the O-forming in a UOE-system steel-pipe manufacturing is remarkably reduced.
