Title: Steel for cold forging
Inventor: ISOGAWA KENJI
IPC: C22C38/14
Filed: 1984-04-27
Abstract: PURPOSE:To obtain the titled steel superior in cold forgeability and high frequency quenchability being the inverse characteristic relating C content by contg. prescribed ratios of C, Si, Mn, B, Ti, Sol, Al respectively therein. CONSTITUTION:The cold forging steel is composed of, by weight 0.25-0.65% C, <=0.15% Si, <=0.60% Mn, 0.0005-0.0050% B, <=0.050% Ti, 0.015-0.050% Sol, Al, and the balance Fe. The cold forgeability of the steel is good by decreasing contents of Si and Mn even in high C content. Especially by decreasing Mn content, the hardness is decreased by increasing primarily deposited ferrite quantity and pearlite lamellar interval of the material as rolled. Furthermore, lowering of the quenchability due to decreases in contents of Si and Mn is compensated by adding B and Ti.

Title: Image recorder
Inventor: HASHIMOTO HIROSHI
IPC: B41J29/48
Filed: 1993-04-13
Abstract: PURPOSE:To reduce the frequency of recording paper feed stops caused by occurrence of jamming by a method wherein whether a paper feed abnormality is eliminated within a fixed period of time is judged based on the detection result of a paper detection sensor, and a paper feed processing is brought to a stop if the judged result is negative. CONSTITUTION:A printer control part 26 detects an abnormality of jamming by detecting a leading end of paper by a paper feed sensor 29 and monitoring a time by a timer 26a. If identifying a failure to eliminate jamming after a fixed time counted by the timer 26a by the detection result of the paper feed sensor 29, the printer control part 26 stops a recording paper feed action. If the paper feed abnormality is spontaneously eliminated, the detection result of the paper detection sensor is reversed. From this standpoint, the spontaneous elimination of a paper feed abnormality is detected by a judging means, whereby the paper feed action is continued. In this manner, when a paper feed abnormality temporarily occurs but is spontaneously eliminated, a conventional abnormality stop processing is not conducted. As a result, the frequency of abnormality recovering operations by a user is reduced.
