Abstract: PURPOSE: To obtain a systematic paper card punch and print device by providing a means which controls a punch and feed part a means which controls a print part, and a means which counts code board clocks and synchronizing the punch feed operation and the print operation with each other.  
     CONSTITUTION: When print operation start signal S1 for the last line of print control PRCONT is sent to punch feed control 1 PFCONT, PFEONT returns response signal OK. Simultaneously, reset signal RS or start signal STA is applied to main clock counter MCCTR and sub-clock counter SCCTR which count clocks of a code board. The carriage and DC feed are controlled by the program of PRCONT, and the punch feed operation is controlled by the program of PFCONT. The punch feed operation and the print operation can be started simultaneously by observing contents of MCCTR and SCCTR by both programs, so that a punch and print device where punch feed and print are synchronized with each other can be obtained.

Title: Electronic unit
Inventor: KAWAMURA TOSHIYA
IPC: H04M1/02
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To eliminate an ineffective space above a support plate to store a sounding body and to reduce the scale of an electronic unit by placing the sounding body to make it overlap partly a position set under the support part and covering the back side of the sounding body by a back case. SOLUTION: A support plate 2 of synthetic resin has a bowl shape, and the inside of a projection part 3 formed by extending outside a part of the opening edge of the plate 2 is used as a front air chamber 4 together with a through-hole 5 prepared at the top face part of the chamber 4. Meanwhile, a sounding body 6 is placed so as to partly overlap the chamber 4 formed under the through-hole 5 and also a lower part of the plate 2 respectively. Then the back side of the sounding body 6 is covered by a back case 7. Thus, a back air chamber 8 is formed. As a result, both chambers 4 and 8 are formed at the front and back of the body 6. Furthermore, the chamber 4 can well function without extending unnecessarily a part of the outer edge of the plate 2 to form a large space since the rising height of the part 3, i.e., the space volume consisting of the thick part of a display 1 is large.

IPC: H04L1/00
Filed: 1993-06-29
Abstract: PURPOSE:To provide an error rate measuring device with high versatility and reliability performance in which a system error rate of various transmission line codes is measured accurately. CONSTITUTION:An M series signal generator 10a generates a predetermined M series signal and gives the generated signal so a tri-state value transmitter 2 as a 1st binary signal. An n-bit delay circuit 51a delays an M-series signal generated by the M series generator 10a by a predetermined bit number and gives the result to the tri-state value transmitter 2 as a 2nd binary signal. An exclusive OR arithmetic operation circuit 52a calculates exclusive OR of two binary signals generated by a tri-state receiver 3 and gives the result to an error counting means comprising a comparator 52c and a counter 52e. The error counting means compares an M series signal generated by an M series signal generator 52d with an output signal from the exclusive OR circuit 52 to count a dissident bit number.

Filed: 1980-11-11
Abstract: PURPOSE: To improve the opening/closing of a fluid passage by providing a large diameter portion of predetermined width on a piston head guide circumferential surface preventing direct contact of the piston head with a valve seat thus minimizing the flow constriction effect.  
     CONSTITUTION: A gap is given between a valve seat 103 a valve body 107a of a large diameter portion of a piston which comes in contact with the valve seat in proximity of the end at the side where an annular guide surface 104a of a back-up 104 comes in contact with the valve seat 103. Thus the flow passage area which changes at the time of the flow passage opening/closing is determined by (circumferential length of the large diameter portion of the piston) X (gap length between the valve seat and the valve body) thereby minimizing the constriction effect of the fluid passage for improved opening/closing of the passage.

Title: Speed detecting apparatus
Inventor: KUBO KEIJI
IPC: G01P3/48
Filed: 1989-06-21
Abstract: PURPOSE:To decrease the detection errors in speed detection at a low speed by obtaining the speed signal by operation based on the differentiated value of a phase signal obtained from a position detector and the sine signal obtained by the change in phase. CONSTITUTION:A laser-interference length measuring system 1 outputs a sine wave whose phase is changed with the change in position. A phase signal 2 and a reference signal 3 are converted into voltages in converters 4 and 5. The voltages are inputted into multipliers 7 and 8 and a 90 deg. phase shifter 6. Filters 9 and 10 pass the low-frequency components of the outputs of the multipliers 7 and 8. The results are inputted into waveform shapers 11 and 12 and differentiators 13 and 14. Multipliers 15 and 16 obtain the product of said outputs. The sum of the outputs of the multipliers 15 and 16 are further obtained in an adder 17. The absolute values of the filters 9 and 10 are obtained in absolute value detectors 19 and 20. The results are inputted into an adder 18. The quotient of the output signals of the adders 17 and 18 is obtained in a divider 21. In this way, the divider 21 detects the signal which is proportional to th speed, and the detecting errors at the low speed can be decreased.

Abstract: PURPOSE: To attempt increase of the contact face pressure and the seal capacity of a seal ring applied to a rotary shaft face or the like, by applying a fluid pressure generated by the operation of a pump to a seal ring projecting toward a pump chamber via a packing plate.  
     CONSTITUTION: On the end face of a rubber-made ring 9 projecting toward a pump chamber, a packing plate 11 made of fluororesin is fitted between a casing 1 and a bearing body 2. When a fluid pressure is generated in the pump chamber by the high-speed revolution of a driving shaft 3, the fluid pressure is applied to the end face of a seal ring 9 via the packing plate 11. As the ring 9 is expanded and deformed radially by its pushing action, the contact face pressure to the driving shaft 3 is increased inside the ring 9, and the contact face pressure between the outside of the ring 9 and the inside of a ring-containing chest 8 is increased via an O-ring 10 located outside the ring 9 for improving the seal capacity.

Abstract: PURPOSE:To shorten a stopping distance safely and certainly by opening slightly an exhaust valve during a period from the final term of compressing stroke to expansion stroke after fuel supplying is stopped at the time of rapid stopping of an engine, and generating a brake cycle in the cylinder of the engine. CONSTITUTION:When an opening side solenoid valve 115 is operated by a controller 122, accumulated oil pressure is shut out, and back pressure of an opening side logic valve 113 is discharged. At this time, the opening side logic valve 113 is opened by high pressure oil in an oil passage 118, and the high pressure oil is led from the supplying hole 112 of an actuator main body 111 into respective supplying holes 108, 109 of a cylinder 106. Since the high pressure oil is applied to respective large and small diameter piston parts 107a, 107b to push down a piston 107, an exhaust valve 102 is opened at a high speed. At the time of rapid stopping, an opening side solenoid valve 115 is opened during a period from the final term of compressing stroke to expansion stroke, and the exhaust valve 102 is opened. It is thus possible to generate a brake cycle in the cylinder 106.
