Title: Control device of two-way francis turbine
Inventor: NOMURA KATSUMI
IPC: F03B15/14
Filed: 1989-02-28
Abstract: PURPOSE:To realize an effective utilization of water by controlling the latter machine responding to the result of comparison of the output of a load controller with a both wheel operation waiting set value and a both wheel operation set value, in a two-way Francis turbine which is converted from a single wheel to the both wheel or inversely depending on the variation of the water level. CONSTITUTION:In the condition that the positive direction of water level variation rate is detected by a water level variation rate detecting device 8 to input the output signal of a water gauge 1, and when the output of a load control device 4 to generate the output to control the load from the relation of the actual water level and the standard water level 2 exceeds the both wheel operation waiting set value 77m1, the inlet valve of the latter machine is opened by the output of a return comparator 15. Furthermore, when the value exceeds the both wheel operation set value 77m2, the guide vane of the latter machine is opened by the output of a return comparator 16. On the other hand, when the output of the load control device 4 is reduced lower than the 77m2 in the condition that the negative direction of water level variation rate is detected, the guide vane of the latter machine is fully closed, and when it is further reduced lower than the 77m1, the control is made to close fully the inlet valve of the latter machine.

Title: Discharge-pumped pulse laser device
Inventor: MIYAZAKI YOSHIHISA
IPC: H01S3/097
Filed: 1990-02-26
Abstract: PURPOSE:To dispense with an exclusive power source for magnetic resetting and simplify circuit constitution and compact the device at large by performing the magnetic resetting of a saturable reactor, using the charge currents for accumulating energy in a charging capacitor. CONSTITUTION:If repeated operation of 1kHz is performed in the case where the capacitance of charging capacitor 14A is 40nF, and charging voltages is 30kv, as the charge current is at least 1.2A or more, the magnetic resetting of a saturable reactor 18 can be done enough. Moreover, for example, if the DC constant voltage power source for 400Hz operation is used, the charge current is 0.48A or more. With this value, it can not be said to be enough for the magnetic resetting of the saturable reactor 5, but the increase of the number of windings of a cable 34 will suffice for using, for example, a saturable reactor 18, and if it is once winding when the charge current is 0.48A or larger, it becomes equivalent to that the reset currents of 0.96A or larger is let flow with twice winding, and it becomes possible to preform enough magnetic resetting.

IPC: D05B21/00
Filed: 1991-02-18
Abstract: PURPOSE:To form the pattern in the desired direction such as the parallel direction, etc., against a pocket, etc., attached to cloth by inputting values in the horizontal and the vertical directions against a reference point on the cloth by a numeral key, and determining the direction of the embroidery pattern. CONSTITUTION:In order to determine an inclination of cloth, a value in the horizontal direction and a value in the vertical direction inputted by a numeral key are determined by measuring the upper edge 41a of a pocket 41 of cloth 40 set to an embroidery frame 12. For instance, a side 42a of a triangle 42 is aligned with a point E of the upper edge 41a of the pocket 41 of the cloth 40, so that the side concerned becomes parallel to a mark of the embroidery frame 12, and it is moved in parallel so that a side 42b passes through a point F, and dimensions (f) (EG) of the side 42a in that case and dimensions (e) (GE) of the side 42b are read as the value in the horizontal direction and the value in the vertical direction, respectively. The value in the vertical direction is read as (+) and (-), in the case the point F is upward against the point G and in the case it is on the opposite side, respectively. From the value (f) in the horizontal direction and the value (e) in the vertical direction which are inputted, an inclination angle is calculated and derived by an inclination angle arithmetic means.

IPC: H04N1/29
Filed: 1987-02-28
Abstract: PURPOSE:To decrease fluctuation in toner concn. and to permit maintenance-free control thereof by selecting the function and threshold value in a computing element at adequate value. CONSTITUTION:An incoming binary picture signal 1 is transiently stored in a frame memory 2 and the signal 1 outputted from the memory 2 enters an integrating counter 3 of black bits on one hand. The bit number of the black level in the picture signal is then integrated for one page. The signal 1 outputted from the memory 2 is inputted on the other hand to a histogram generator 4. The data on the black bit number from the counter 3 inputted to the computing element 5 and the data on the central value and standard deviation from the generator 4 are passed through the element 5 and are integrated as the black bit number subjected to correction by an image pattern in a 2nd integrating counter 6. A comparator 7 operates an operation circuit 9 for replenishing a toner and outputs a clear signal 10 to return the value of the counter 6 to 0 when the comparator 7 detects that the integrated value of the corrected black bit number exceeds a threshold value 8.
