Patent JP-S62136112-A (JP)
Title: Transistor mixer circuit
Inventor: SAKATA MINORU
IPC: H03D7/00
Filed: 1985-12-10
Abstract: PURPOSE:To prevent the deterioration in a two-signal characteristic and the oscillation of a transistor (TR) by providing a matching circuit absorbing an intermediate frequency component to a base side of a TR mixer. CONSTITUTION:A matching circuit M is added between an input side of an input matching circuit and ground. Since inductance L2 of the circuit M is selected to a high impedance to a reception high frequency signal from filters F1, F2 and a local oscillation signal and a low impedance to an intermediate frequency, the said signal is matched by the input matching circuit. Since a parallel circuit comprising an inductance L1, a capacitor C1 and a resistor R1 acts to the intermediate frequency and the impedance comprising the inductance L1 and the capacitance C1 is a high value to the intermediate frequency, only the resistor R1 acts in the circuit M with respect to the intermediate frequency and the intermediate frequency component returned from a base of a transistor mixer TR is absorbed by the resistor R1.

Title: Driving force transmission device with double rack mechanism
Inventor: ICHIKAWA YOSHIHIRO
IPC: G11B21/02
Filed: 1994-10-14
Abstract: PURPOSE: To ensure the engagement by linearly moving a driving rack and a driven rack by rotating the rotating gear whose teeth are elastically held between the teeth of the driving rack and those of the driven rack. CONSTITUTION: Clockwise rotation of a rotating gear 10 causes the driving rack 1 and driven rack 2 to move in the direction of approaching a stopper 20, and this movement is restricted when the end 1p of the driving rack 1 abuts on the stopper 20. Although the driving rack 1 is designed to be unengaged with the rotation gear 10 this time, an extra tooth is formed in the driven rack 2 so that the rack 2 is detached from the stopper 20, and accordingly the tooth 21 at the extreme end of the driven rack 2 abuts on the teeth 10a, 10z of the rotating gear 10 to be surely engaged under the condition of being sandwiched by the two.

Title: Antenna case for plane patch antenna
Inventor: MIZUNO ITSUKI
IPC: H01Q1/42
Filed: 1990-10-17
Abstract: PURPOSE:To ensure the water-proof performance and to reduce the manufacture cost by using foamed styrol for an antenna case, packing the styrol to the inside of antenna main body without a gap, and shaping the case so as to enclose the entire antenna. CONSTITUTION:A general foamed styrol is packed completely in the inside of the antenna main body 20 and expanded also to the outside of the antenna for the case. For example, simple dies 23, 24 are prepared, and the antenna main body 20 is put in them, and a foamed styrol manufacture kit on market is used and a stock solution 25 of the foamed styrol is put in them and the solution is foamed while the dies are covered. Since the foamed styrol packed in the inside of the antenna is extended up to the outside of the antenna as it is and used for the antenna case, there is no room to which rain water drop is invaded. Since the labor cost and the die cost are less, the entire cost is reduced.

Title: Aperture variable camera
Inventor: NAKAMURA YOSHIO
IPC: G03B15/05
Filed: 1991-09-27
Abstract: PURPOSE:To effectively utilize strobe light by changing the strobe light irradiating range of a camera with a built-in stroboscope by interlocking while dividing a standard image plane from a panoramic screen and making a photographic screen range coincident with the strobe light irradiating range. CONSTITUTION:A Fresnel lens plate 2 is fixed on a camera main body 1, and a strobe light emitting part 3 is positioned behind the lens plate 2 so that it can move in a back-and-forth direction. An aperture or exposing 4 having a size corresponding to panormaic photographing is provided is the camear main body 1. By allowing an operation button 9 to side and covering the sperture 4 with mask plates 24 and 30, the aperture becomes an aperture for standard photographing. By exposing the aperture 4, it becomes an aperture for panoramaic photographing. A gap between the stored light emitting part 3 and the Fresnel lens plate 2 is changed by interlocking with the segmenting action of two apertures. Since the gap becomes long at the time of standard photographing, the irradiating range becomes narrow, and it becomes wide since the gap becomes short at the time of panoramic photographing.
