Filed: 1985-06-14
Abstract: PURPOSE:To attain the type printing without troublesome operations in case of only type printing by giving an action mode where a printing action can be instantaneously executed in accordance with an input through a keyboard when a memory medium is not installed. CONSTITUTION:When a power source is turned on, a CPU204, first, discriminates whether or not a flopy disk is mounted on a flopy disk driver 300. When the flopy disk is not mounted, the CPU204 switches a control mode to a type- through mode in accordance with a program stored in a ROM of a memory device 202. When mainly, a letter key part 504 of a keyboard 500 is keyed in the type-through mode, a printer 400 can be operated instantaneously in accordance with said key operation. Thus, a user can execute typing work instantaneously.

Abstract: PURPOSE:To attain stable DA conversion independently of the state change in a digital signal input by selecting an output of a decoder being the result of decoding a count output of a binary counter by using a digital signal input so as to obtain an analog signal output. CONSTITUTION:A decoder 10 decodes a count output of a binary counter 9 to obtain decode outputs 03,02,01 and Oo corresponding to bits D3,D2,D1 and Do of a digital signal A. Suppose that the level of digital signal inputs D0-D3 is 1010 (=5), only the outputs 0o,02 are selected by a selection means 11 to obtain an output S1. The output S1 is normalized from a clock pulse Sck at a normalizing means 12 to obtain an output S2 shifted by one clock only. Since the constitution fetching the digital signal input D0-Dn-1 in a sampling way and applying DA conversion is not used, mis-conversion of a digital signal input into an analog signal as a conventional example is not caused.

Title: Device for detecting abnormality of boom of reclaimer
Inventor: IRIE MITSUHIRO
IPC: B65G65/00
Filed: 1984-06-27
Abstract: PURPOSE:To automatically detect the abnormal state of a boom, by using a detector to find out the rotation of an eccentric shaft, which rotates when there is abnormal deposit on the boom or abnormal load thereon. CONSTITUTION:When the moment of an eccentric shaft 5 during the turning up and down of a boom 1 caused by operating a winch 3 is not higher than the maximum level for normal work, the force of a spring 7 keeps the eccentric shaft 5 from rotating. When the moment of the eccentric shaft 5 is higher than the maximum level, in other words, when there is an abnormal deposit on the boom or abnormal load thereon, the eccentric shaft rotates. The rotation of the eccentric shaft is detected by a selsyn oscillator 8. The abnormal state of the boom 1 is thus automatically found out through a detection signal from the selsyn oscillator 8.
