Title: Cylinder head for internal combustion engine
Inventor: NODA KOJI
IPC: F01P3/02
Filed: 1993-05-26
Abstract: PURPOSE:To let flow cooling water of a required quantity and required flow speed on the combustion chamber wall side so as to enable to exactly cool it by providing a partition wall to partition the cooling water passage in a cylinder head into a lower passage on the combustion chamber side and an upper passage on the valve system side. CONSTITUTION:In a cylinder head, a partition wall 29 which partitions a cooling water passage formed between a lower deck 25 on the combustion chamber 20 side and an upper deck 26 on the valve system side into a lower passage 27 along the lower deck 25 and an upper passage 28 along the upper deck 26 is formed. Hereby, cooling water flowing from an inlet part flows respectively independently in the lower passage 27 and the upper passage 28, and hence more quantity of cooling water can be let flow in the lower passage 27 on the combustion chamber 20 wall side than the upper passage 28. Further, the sectional area of a water passage becomes small by provision of the partition wall, hence the flow speed of cooling water is increased and stagnation of cooling water on the lower stream part of ports 21, 22 is eliminated, and passage resistance is remarkably reduced. Therefore the combustion chamber 20 wall side requiring the strongest cooling can be cooled efficiently and sufficiently.

Title: Cold rolling method
Inventor: MURATANI SHINYA
IPC: B21B1/22
Filed: 1977-10-19
Abstract: PURPOSE:To surely prevent the excess pickling and to contrive the improvement of the productivity, by detecting the line speed on the feeding side of the intermediate coiler, and by controlling the quantity of pickling liquid for the pickling line correspondingly to this detected speed. CONSTITUTION:The speed detecting roller 26 is installed between the drier 17 and the bridle roller 18 on the feeding side of the intermediate coiler. And, correspondingly to this detecting signal for the speed of the strip passing through the pickling unit 10, the flow control valve 14 is adjusted so as to control the quantity of pickling liquid to be injected from the pickling spray 12. In this apparatus, if the roll of the cold rolling mill 22 is to be exchanged, etc., it is necessary that the pickling line speed is previously reduced so as to coil the intermediate coil 21 at a low speed on purpose to gain time. Hereupon, since the strip passes through the pickling nuit 10 at a low speed, the excess pickling is ready to happen; however, the quantity of pickling liquid is controlled by the valve 14 in such a case, so that the excess pickling can be surely prevented.

Abstract: PURPOSE:To improve reliability and to improve service by subtracting a power flow at present time of the own station from a maximum transmission capacity, and comparing the value with a current supply power flow at the opposite end. CONSTITUTION:Since a CBn1 of a slave electric station (n) is a normal open breaker, a normal load is switched to a power source P at the time of a fault in a section from a master electric station 1 to a slave electric station (n-1) to be recovered. In summary, the start from the station 1 is conducted when a power amount P transmitted to the system by a power source P2 is subtracted from a power amount which can be transmitted and previously set and the result is larger than a power flow transmitted from the station 1 before the fault. It is recovered based on the processed content, a breaker CB11 is opened at the time of fault of an L1 to disconnect the faulty section L1. Then, the normal open CBn1 is closed to recover the stations 1, 2 in a short time.

Abstract: PROBLEM TO BE SOLVED: To prevent a steady-state phase error and jitter or the like from being increased by adding an output voltage of a filter to a voltage at any connecting point of two circuit elements or over and generating an output signal with a frequency in response to the sum voltage. SOLUTION: At first a phase comparator 1 provides an output of a signal denoting a phase difference between a reference signal and an output signal, a charge pump 2 provides an output of a current in response to the signal denoting the phase difference to a filter 3. An output voltage of the filter 3 and a voltage of a tap of the filter 3 are respectively given to voltage current conversion sections 101, 102. The voltage current conversion sections 101, 102 supply a current being a multiple of 'kg' of the received voltage and a current being a multiple of 'kg-1' of the received voltage to a current voltage conversion section 3 respectively. The conversion section 103 converts the received current into a voltage and gives it to a voltage controlled oscillator 4.  The oscillator 4 is driven so as to oscillate a signal with a frequency in response to the received voltage and this PLL circuit obtains an output signal with the same phase as that of the reference signal.
