Filed: 1985-04-03
Abstract: PURPOSE:To facilitate the assembly of an electric fan, by providing a ring around the front or rear guard of the fan, and providing elastic ribs on the inside surface of the ring along almost the total circumference of the ring. CONSTITUTION:A ring 6 having a handhold 7 at the lower portion of the ring is provided around the edge of a front guard 5, which covers blades 4. A plural ity of elastic ribs 8 for holding the peripheral wire 3a of a rear guard 3 are provided on the inside surface of the ring 6.

Title: Laser fillet welding method
Inventor: YOSHIDA YASUYUKI
IPC: B23K26/21
Filed: 1985-04-03
Abstract: PURPOSE:To execute welding with high accuracy and high efficiency by providing a single-Vee groove to base metals to be fillet-welded and irradiating laser beams along the groove faces from both sides of the base metal. CONSTITUTION:The groove having a single Vee section is formed with base metals 1, 2 to be fillet-welded and the base metals are combined. The laser beam 3 fro a laser light source is exactly bisected by a half mirror 7. The laser beam 31 past the half mirror 7 is condensed by a condenser lens 41 and is bent at the same angle as the angle of the single Vee groove by a bent mirror 51 and is irradiated to the groove 8. On the other hand, the laser beam 32 reflected by the mirror 7 is again bent 90 deg. in the optical path and while the beam is condensed by a condenser lens, the beam is irradiated by a bent mirror 52 to the groove 8. The fillet welding is thus executed while the laser beam 3 is irradiated to the groove 8 from both sides of the base metal in the above- mentioned manner.

Title: Colored styrene polymer composition
Inventor: HORIE SHINJI
IPC: C08L25/04
Filed: 1987-03-25
Abstract: PURPOSE:To obtain the title composition which is useful for an electrophotographic color toner and does not undergo deterioration of hue due to the diffusion of a colorant and degradation of the chargeability, etc. of the composition, by mixing at least two specified styrene polymers with a colorant. CONSTITUTION:At least two styrene polymers which have glass transition points of 40-115 deg.C, number-average MW's of 2,000-200,000 and differ in the affinity (e.g., acid value due to the functional groups introduced) for a colorant are mixed with a powdery colorant having positive chargeability and comprising an organic dye such as Rhodamine B or an organic pigment such as phthalocyanine. In this way, the colorant bonds to the styrene polymer which is higher in affinity, which causes microphase separation between the styrene polymers and, in turn, prevents the colorant from diffusing into the other styrene polymer.

Title: Radio receiver
Inventor: HONDA KAZUHIRO
IPC: H04B1/18
Filed: 1987-03-25
Abstract: PURPOSE:To respond to high impedance formation according to the miniaturization of a micro strip antenna(MSA) and to easily perform matching, by using the MSA as a reception antenna, and using an active device with high impedance as an amplifier at first stage whose input terminal is connected to the feed point of the antenna. CONSTITUTION:An RF amplifier 10 inputs a high frequency reception signal from the MSA16 to the input terminal, and amplifies it at a FET18, and outputs it to a mixer 11. At such a time, a resistor R1 is constituted so that the impedance can be set freely by varying the value. And since the input impedance of the amplifier 10 that is the amplifier at the first stage of a reception circuit 9 is set higher than the impedance of the FET18 that is the device with the high impedance even when the input impedance goes high due to the miniaturization of a device, impedance matching with the MSA16 can be obtained. Fine adjustment at the time of the matching can be performed by the register R. Therefore, it is possible to reduce unmatching loss between the antenna and the reception circuit by performing easily the matching and obtaining the matching.

Title: Static memory
Inventor: YAMAGUCHI HIROYASU
IPC: G11C11/40
Filed: 1980-05-28
Abstract: PURPOSE:To decrease the number of element and that of wirings and to write data with infinite impedance, by controlling the writable state switching of a memory by providing a clocked gate and by controlling data transmission by FETs differing in polarity. CONSTITUTION:Address write signals AW and AW', each consisting of an address signal and a write signal, are applied to the FF11 of a static RAM equipped with an inverter I, a clocked gate CG, etc. Then, a gate CG turns off to cut off a feedback loop, so write impedance becomes infinite, thereby setting a writable state. On the other hand, a P type FETT1 and an N type FETT2 for transmission between the FF11 and a bus line BUS are driven with the address signal A and write address signal AW respectively, data is transmitted via the FETT1 or T2 according to the high or low level of the data on the line BUS and then written in the FF11. Similarly, the data is read out and while a small number of parts, such as eight elements and four wirings, are required, writing operation is carried out with infinite impedance, eliminating the need to consider the balance in impedance among respective parts.
