Title: Printer
Inventor: SATO HIROSHI
IPC: B41J19/18
Filed: 1991-03-06
Abstract: PURPOSE:To prevent a carriage from coming into collision with a cover by a method wherein in a printer provided with a cover-mounting opening through which a part of the carriage mounted with a printing head is projected outside a body when the carriage is driven, whether the movable cover is opened or closed is detected, and only when the cover is opened, the drive of the carriage is permitted. CONSTITUTION:A carriage 7 mounted with a printing head is so constructed inside a body 1 as to reciprocate along a platen. When a printer is required to be made small, e.g. in a lap top-type computer, an opening 11 for exposing a part of the carriage 7 is formed on one side surface of the body 1. A movable cover 12 is mounted on the opening 11 so as to be opened and closed. A microswitch 13 as a detecting device is provided inside the opening 11 on the upper part thereof and turned ON/OFF by a projection 14 provided on the upper inner surface of the movable cover 12. Only when the movable cover 12 is opened and the microswitch 13 is turned OFF, the carriage 7 is driven under the control of a control circuit.

Title: Heat responsive device utilizing shape memory spring
Inventor: OONO AKIRA
IPC: F03G7/06
Filed: 1983-03-11
Abstract: PURPOSE:To permit to be used for an use which is narrow in an operating temperature range by providing a stopper stopping the shape memory spring at a predetermined operating stroke to reduce the temperature hysteresis of the spring. CONSTITUTION:When temperature is low, a load for a weight 3 tries to compress the spring 1, whose spring constant is weakened, to the lower side of the stopper 5; however, the first stopper 5 receives it. Accordingly, the load of the weight 3 is supported by the resilient force of the spring 1 and the first stopper 5. On the other hand, when the temperature is high, the spring 1 tries to expand more than the operating stroke L thereof; however, the second stopper 6 precludes the restoration exceeding the operating stroke L. Accordingly, the temperature hysteresis may be restricted to a small amount.

Abstract: PURPOSE:To enable display of an image of an aimed subject for observation under sufficient brightness even when the subject for observation is relatively wide or deep by providing a variable gain amplifier which performs amplifying process of video signal, a level detection circuit and a gain adjusting circuit. CONSTITUTION:A light quantity controlling circuit 9 controls a diaphragm so that the quantity of light applied to a subject for observation is set at an appropriate value. Also the level of a video signal formed becomes constant, and when the inside of the subject for observation is wide or deep, a sufficient quantity of light cannot be applied thereto and the level of the video signal is lowered. But the level of the video signal output from a gamma correction circuit 11 is detected at a sample gate pulse by a detection circuit 24 and a hold voltage is supplied to a gain adjusting circuit 26. An operation amplifier 25 located inside the gain adjusting circuit 26 compares the hold voltage with a reference voltage Vref and supplies the differential voltage to an AGC amplifier 16 and converts the gain of the amplifier. As a result, the level of the video signal is so controlled as to be constant.
