Title: Device for detecting abnormality of punch of head forming machine
Inventor: MAKINO ISAO
IPC: B21K27/00
Filed: 1989-08-29
Abstract: PURPOSE:To severely detect the abnormality of a punch without receiving the influence of ambient temperature by detecting the advance limit of the punch, comparing its value with a criterion to decide the abnormality of each punch and updating the deviation of the criterion. CONSTITUTION:The advance limit of the punch of a head forming machine is detected by a sensor, a specified value of a detected value is stored and its average is made a criterion. The succeeding detection values are compared with the criterion and whether the advance limit of the punch is abnormal or not is decided in accordance with the deviation. When it is decided to be normal, the absolute value of the difference between the detection value and the criterion and the temporary deviation from this absolute value are calculated. The temporary deviation is compared with this specified deviation and when the temporary deviation is larger than the specified deviation, this temporary deviation is stored as a new deviation to perform the following decision. When the temporary deviation is smaller than the specified deviation, the following decision is performed at once. In this way, an extreme rise only of the detection value due to the abnormality of the punch can be detected.

Title: Keyboard repeat control system
Inventor: SAKAMOTO HIROYUKI
IPC: G06F3/023
Filed: 1983-11-30
Abstract: PURPOSE:To finish instantaneously a repeating action by storing the key codes generated by a key code generating means to a key code buffer according to the flag information stored in the 1st flag memory. CONSTITUTION:A RAM1713 is used as a keyboard buffer KBBUF and also allocated to areas as a repeating counter RCNT and various flag memories. When a keyboard unit is scanned or it is needed to send a key code to a data processor in a repeating process, the corresponding key code is stored to the KBBUF and then sent to the data processor. In this case, a CPU1711 of a keyboard control circuit checks a keyboard buffer empty flag BEF and stores the key codes only when the KBBUF is empty. This avoids the undesired store of key codes in the KBBUF in a repeating mode.
