Title: Staircase wave generating circuit with variable step
Inventor: YAMADA OSAMU
IPC: H03K4/02
Filed: 1982-03-26
Abstract: PURPOSE:To realize variable step staircase waves in which the number of steps is switched accurately, by inserting one stage of an amplifier with variable gain to an analog integration circuit used conventionally. CONSTITUTION:In a changeover switch 7, when the gain of the variable gain amplifier 5 is unity and the frequency dividing ratio of a frequency divider 6 is turned on to a position of 1/2<11>, a Miller integration circuit comprising an operational amplifier 1 is reset with a switch 4 closed by means of a monostable multivibrator 3 every time when a horizontal blanking pulse is inputted to 2<11> times (2,048 times), and staircase waves of 2,048 steps are generated repetivively. When turning on the switch 7 to the 2nd notch position, the Miller integration circuit is reset every time when the horizontal blanking pulse is inputted by 2<10> times (1,024 times) and generates staircase waves of 1,024 steps repetitively. Similarly, the changeover switch 7 switches the frequency dividing ratio and the gain of the variable gain amplifier interlockingly, allowing to change over the number of steps of the staircase waves as 512, 256 and 128 steps accurately.

Title: Safety device at starting time of high-pressure water pump
Inventor: FUJIKAWA TAKAFUMI
IPC: F04B49/02
Filed: 1981-03-31
Abstract: PURPOSE:To reduce the frequency of air removing operation required for an operator to perform before starting a high-pressure water pump, by circulating water through provision of a  head tank, preventing intrusion of air into the high-pressure water pump, and providing a  safety device which disables the pump from starting if air is introduced into the pump. CONSTITUTION:Through provision of a head tank 15, water is always filled in the system even  during the while when a high-pressure water pump 6 is at rest in so far as the level of water  in the head tank 15 is located between a high level and a low level of a water gauge 18 for  the head tank 15, so that intrusion of air into the system is prevented. However, if the pump 6  is kept at rest for long time, the level of water in the tank 15 becomes lower than said low level of the water gauge 18 due to leakage of cooling water for cooling bearings of the pump  and leakage of water to a water tank 1 through a check valve 3, so that intrusion of air into  the pump 6 can be expected. In order to overcome the above problem and to prevent occurrence of accidents, the system of this invention incorporates a safety device which lights an  alarm lamp on a control board 21 of the pump 6 when the water level becomes lower than  said low level of the water gauge 18, stores the temporary drop of water level into memory,  and disables the pump 6 from starting until air removing operation is completed by an operator. Here, the frequency of air removing operation required is reduced considerably by the function of the head tank 15.
