Title: Low noise active mixer
Inventor: NATSUTO EMU GIYUEN
IPC: H03D7/14
Filed: 1994-06-28
Abstract: PURPOSE: To perform the input matching of circuits with no deterioration of noise value and to improve the linearity by connecting together both emitters of transistors TR A and B of a matching pair of radio frequency via an inductor (a) and connecting an input to the base of the TR A via an inductor (b) respectively. CONSTITUTION: The 1st and 2nd local oscillator matching pairs of TR Q1/Q2 and Q3/Q4 respectively are connected to a radio frequency matching pair of TR Q5 and Q6 via a coupling means. In such a connection way, a Gilbert cell is obtained and used to a double balanced mixer. Then a thin film spiral inductor LE is placed between both emitters of TR Q5 and Q6 of the mixer. A resistance RI uses a metallic wire of the inductor LE and attains the reactance feedback between both TR Q5 and Q6. Then the radio frequency input VRF is inputted to the base of the TR Q5 via an input inductance LI. Thus, the input matching of circuits is attained with no deterioration of noise value and the linearity is improved.

Title: Image forming device
Inventor: HANEDA SATORU
IPC: G03G15/01
Filed: 1987-07-07
Abstract: PURPOSE:To obtain a satisfactory, single-colored image free from image dislocation and of color blurs by repeating image exposure and development using color toner on an image forming body several times based on data on a single image, thereby forming a single-colored image. CONSTITUTION:First time, an electrifier 12 uniformly electrifies the surface of the image carrier 11 in an initial status, and image exposing light beams 14 in different colors generated by a laser beam scanner are projected on the electrified surface, thereby performing a 1st image exposure in which the potential of an electrostatic latent image part is considerably lowered. Among developing units 15-18, the one using a developer with a colored toner T1 corresponding to the image exposing light beam 14 develops an obtained electrostatic latent image 51 first time. When the next image carrier 11 is rotated secondary, the electrifier 2 is used to perform the same image exposing light beam 14, and another developing device using a developer with a colored toner T2 corresponding to said beam 14 develops the same electrostatic latent image 51. Hence onward, development is repeated similarly, and an arbitrary single-colored image is formed of respective color developers overlapped on the same toner image. Thus the single-colored image free from image dislocation and color blurs can be obtained.

Abstract: PURPOSE:To improve durability of the periphery of a through-hole, and improve an installing performance by providing the through-hole penetrating through a fixed surface and a sliding surface as an oil flow hole, and reducing sliding resistance by forming an oil film on the sliding surface. CONSTITUTION:A rigid member 4 and a lining 5 are brought into pressure contact with each other, and are formed as a main body of a journal bearing 1. A projecting part 9 having a hole 8 to constitute an oil flow passage 7 by being formed integrally with a through-hole 6 of the main body, is arranged on the fixed surface 2. As a result, when the projecting part 9 is fitted to an oil passage 12 of a connecting rod 10 or the like, reliable positioning becomes possible, and the opening area of the oil flow passage 7 to the oil passage 12 is secured easily and reliably. Since the periphery of the through-hole 6 is reinforced by the projecting part 9, deformation around the through-hole 6 caused by an oil pressure change in an oil film formed on a sliding surface 3 is restrained, and durability against separation of the lining 5 is improved.

Abstract: PURPOSE:To make it possible to form electrode wiring with low contact resistance and high reliability to fine silicon contact by forming aluminum electrode wiring containing silicon in a silicon contact hole, and then covering it with high melting point metal by the selective CVD method. CONSTITUTION:To a shallow n<+> diffusion layer 2 formed at a silicon substrate 1, a contact hole 4 is formed in an insulating film 3, and then aluminum 5 containing silicon by 1-2% is accumulated so as to form the pattern of electrode wiring. Accordingly, silicon modules 6 that the aluminum is excessive are precipitated with very small grain diameter in the aluminum 5 in large numbers, and a tungsten film 7 grows only at the surface of the aluminum electrode wiring 5. Since this tungsten film 7 is formed by the CVD method, isotropic growth can be done and step coverage improves remarkably. Hereby, by the simple method, electrode wiring with low resistance and high reliability to a fine contact hole can be formed.

Filed: 1990-06-27
Abstract: PURPOSE:To make the best use of an advantage inherent in a claw clutch as well as to enable its off-operation to be done lightly by installing the claw clutch and a friction clutch both in a transmission system in parallel, and constituting this friction clutch to be disengaged after the off-operation of the claw clutch. CONSTITUTION:When a claw clutch 7 and a friction clutch 8 both are in a state of being engaged, power of a first power transmission shaft 4 is parted in each of these clutches 7 and 8 parallelly and surely transmitted to a second transmission shaft 9 in utilizing an adtange inherent in the claw clutch 7. At time of off-operation, first a shift member 11 of the claw clutch 7 is operated slidingly to the right. At this time, since the power is made to flow into the friction clutch 8 as well, contact surface pressure in two projections 10a, 11a of the clutch 7 is small, so that the shift member 11 can be slidden to the right lightly, whereby the claw clutch 7 comes to a state of being disengaged. When the shift member 11 is further slidden to the right, a friction disk 14 separates from a friction disk 16, thus the friction clutch 8 comes to a state of being disengaged as well, and transmission to the second transmission shaft 9 is interrupted.

The temperature distribution control plate 20 consisting of two steel sheets 18 and 19 allows their relative position to change so as to vary the overlapping degree of their respective through holes 18a and 19a, thereby adjusting the quantity of air flowing into a bath. The hot air which has passed through the temperature distribution control plate 20 is turned into hot air 22 and 23 and the like with the desired air quantity and, after passing through a lower porous steel plate 7, is converted into the hot air 14 to be cycled again. According to this constitution, the fluctuation of a temperature can be prevented, and increase or decrease in the quantity of air directed to every part of the interior of a constant temperature bath can be easily changed.
