Title: Camera
Inventor: NAGATA TORU
IPC: G03B13/02
Filed: 1985-08-07
Abstract: PURPOSE:To operate efficiently a camera which makes an image display by an electrooptic device using liquid crystal, etc., by allowing a finder housing which has a display surface at some angle to an optical axis of photography to rotate on the camera body. CONSTITUTION:The support frame 19 of the finder housing 3 is fitted rotatably in the camera body 2 with support metal 20. When the camera is held in a horizontal state, light from the LED11 of the main body 2 is incident on the Si photocell 14 of the housing 3 and a finder position detecting circuit sends a signal indicating the horizontal position to a processing circuit. Then, the processing circuit drives an image transfer circuit so as to display the information of the sensor 8 on the upper 2/3 part of the display surface and an information input part below it. When the camera is held in a vertical state, on the other hand, the housing 3 is rotated by 90 deg. from the horizontal position, so the light from the LED11 is not incident on the Si photocell 14. The position detecting circuits sends a signal indicating the vertical position to processing circuit. Then, the information of the sensor 8 is displayed on the left 2/3 part of the image surface an the information input part is displayed on its left side.

Title: Transfer line for rough strip steel
Inventor: OTANI NOBUHISA
IPC: B21C47/02
Filed: 1986-07-24
Abstract: PURPOSE:To stabilize a hot rolling work and to improve the quality of a product by setting the upper face height of the roll of the inlet side table for a coil box so as to locate it at the upper part than the lower roll lower face of a bending roll. CONSTITUTION:The upper face height position of the roller 1a of the inlet side table 1 onto a coil box is set at the position lower than the lower face of the lower roll 3c of the bending roll 3 consisting of three rolls 3a, 3b, 3c. A rough strip steel S can thus be led to the bending roll 3 smoothly without its collision with a deflector roll 2 even in the case of the thickness of the rough strip steel S being thin or the stiffness being low due to high temp. Consequently the clogging of the tip of an ingot piece S and the meandering generation while under winding can be prevented. The hot rolling work is therefore stabilized and the product quality is improved.

Patent JP-H0927782-A (JP)
Title: Radio equipment
Inventor: ASAI NOBUO
IPC: H04B7/26
Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption by providing a first timer for setting on-and off-intervals for intermittent reception and a second timer, for which the on-interval is longer than that of the first timer, to be operated after carrier detection. SOLUTION: While controlling the 'on' and 'off' of a power source 13 at the intervals set by a first timer circuit 1 under the control of a power supply control circuit 14, inputted radio waves are demodulated and transmitted to a CPU 20. Only when an interrupt signal from the circuit 15 is inputted, the circuit 14 is controlled, the power source 13 is turned on, and the presence/ absence of carrier is checked. When there is no carrier, the circuit 14 is controlled to stop supplying power to a radio part 12, radio equipment itself is turned to a standby state and power consumption is suppressed. When the presence of carrier is judged, a second timer circuit 16 is operated and during that operation, received data are monitored at all times.  Thus, even when data can not be completely caught, the equipment always starts and monitors the received data only while the circuit 16 is operated.
