Title: Phase compensator
Inventor: OKABE KAZUO
IPC: H03K5/26
Filed: 1988-04-19
Abstract: PURPOSE:To form a phase compensator which is inexpensive even to high speed data by selecting plural delayed data in corresponding to an A/D- converted value and appropriately compensating the phases of the date and clocks. CONSTITUTION:The output of the 1st edge detector 3 against a data input 1 becomes negative output pulses at the leading and tailing edge sections and the output of the 2nd edge detector 4 to a clock input 2 becomes negative output pulses at the leading edge section. The voltage averaged by a rectifier 6 is A/D-converted by means of an A/D converter 7. Since the output of the rectifier 6 is proportional to (tau), namely, the phase relation between the inputs 1 and 2 when the time constant is longer than the scrambling period, the data and clocks can be outputted after the phase relation between the data and clocks is appropriately adjusted. Therefore, a phase compensator which is inexpensive even to high-speed data can be obtained.

Abstract: PURPOSE:To cast continuously a chain without damaging a product by providing a groove for guiding a cord chain and a groove meeting a product delivery rod to upper and lower dies and delivering successively the product by the forward and backward movement of the rod. CONSTITUTION:A groove 10 which guides a cord chain 4 and a groove meeting a product delivery rod 3 are formed to upper and lower dies 1, 2 in production of a cast net for a fishing net formed by passing products 5 onto a cord chain 4, etc. The chain 4 is brought into press contact by the dies 1, 2 and after the product 5 is cast, the die 5 is opened and the rod 3 is moved back and forth for a prescribed distance to deliver the product 5. The chain 4 wound on a rotary drum 9 is thus unwound and is pulled via V-pulleys 6, 7. The chain 4 attached with the product 5 is advance by a V-pulley 8 toward a perpendicular direction. The products 5 are thus successively cast on the chain 4 by the dies 1, 2.

IPC: G06F9/30
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To reduce increase of a code size and the hardware amounts of an instruction decoder even at the time of mounting a conditional instruction. SOLUTION: When an intermediate code is inputted, this compiler executes a series of processing for changing a comparison code for judging an instruction executing state to a conditional comparison code for judging the specific condition of a conditional code, deleting the conditional code, arranging the first operation code after the second operation code, and changing the first operation code to an execution code at the time of condition establishment to be executed only when this matches the specific condition. Thus, the condition of the conditional instruction can be applied only when the condition is established. Therefore, the increase of a code size can be reduced only by designating only one condition for all the conditional instructions.

Abstract: PURPOSE:To reduce the cost of an automatic control device by executing an automatic control mode of a wiper device as required without complicating a raindrop sensor. CONSTITUTION:In is decided at steps ST1-4 whether wiper operation is effected within a given time from the start time of automatic control (within one second after start of wiper or within 30 seconds after start of running), and when wiper operation is effected, a waiting mode is executed at steps ST5-10. It is decided at a step ST12 whether wiper operation is effected within 30-120 seconds after the start of the waiting mode. When wiper operation is effected, a wiper main control mode is executed and when no wiper operation is effected, a defroster mode where wiper automatic control is not effected is executed.
