Title: Assembly hob
Inventor: KAWAUCHI HIDETO
IPC: B23F21/16
Filed: 1986-01-09
Abstract: PURPOSE:To aim at increasing the machining number of gears for each hob, by press-fitting flexible pins in both end parts of grooves formed in a hob body and a blade to increase the blade length ratio with respect to the overall length of the hob. CONSTITUTION:A plurality of blade receiving grooves 2 having a rectangular cross-section are axially formed in the outer peripheral surface of a hob body 1. Further, a triangular cross-sectioned shape groove 9 is formed in each receiving groove 2, and a similar triangular cross-sectioned shape groove 10 is formed in each blade 3. These grooves 9, 10 define a rectangular cross-sectioned shape spaces (grooves). Radially flexible pins 11 are press-fitted in both end parts of each space to prevent the blades 3 from being shifted radially of the hob body 1 due to cutting force acting upon the blades 3. Further, since the radially securing manner for the blades 3 is changed, it is possible to shorten the length l1 of the hub.

Title: Signal reception circuit in carrier equipment
Inventor: OTSUKI MITSUO
IPC: H04M3/22
Filed: 1986-01-09
Abstract: PURPOSE:To facilitate the detection of an electric circuit and to improve the reliability by providing a manual switch, operating the switch to bias a transistor (TR) into the cut-off state or the forward bias state. CONSTITUTION:A signal pulse from an input terminal 1 is controlled by a clock from a clock supply terminal 2 and outputted to a Q terminal of an IC. The positive voltage of signal pulse cuts off a base current IB 1 of a TR Q1. The current IB 1, at zero voltage of the signal pulse, flows to a receiving terminal 5 from an exchange side through a resistor R2 and a collector of a TR Q3 even with 1-2 or 2-3 connection of a changeover terminal 6. The changeover of the terminal 6 is to select whether a relay drive current is to be flowed or stopped when a power converter is faulty and power failure takes place, the relay drive current is shut off with the 1-2 connection and the relay drive current flows with the 2-3 connection. The titled circuit is used for both the exchange type where the relay drive current glows to prevent simultaneous start at the power failure due to the failed converter and the type where the relay drive current is shut off to prevent simultaneous start.
