Title: Gas-liquid separating structure
Inventor: KUBOTA ETSURO
IPC: F25B43/00
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To improve the yield of a gas-liquid separating structure by preventing the occurrence of defective connection between a heat carrier flowing pipe and the main body of a liquid receiver by brazing. SOLUTION: A heat carrier flowing pipe (header pipe) 2a is provided with a partition plate 90, which separates a part of a heat carrier flowing out to the main body 11 of a liquid receiver 11 from another part of the heat carrier flowing in the pipe 2a from the main body 11, and the plate 90 is integrally formed of a plate section 91 inserted into a slit 9c of the pipe 2a and a head section 92 which comes into contact with the opened end of the slit 9c. The main body 11 has a stay 17 brazed to the pipe 2a and is constituted to give and receive the heat carrier to and from the pipe 2a through through-holes 12 and 13 of the stay 17. The stay 17 has a groove 17b, which houses the head section 92 of the partition plate 90 protruded from the pipe 2a.

Title: Ink jet print apparatus with function of preventing head- rubbing by manually inserted seal paper leading end
Inventor: OZAKI TATSUMI
IPC: B41J2/01
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To prevent a leading end of a manually inserted seal paper from rubbing a head by using the manually inserted seal paper for a means for printing images and cutting the seal paper at a right corner of the leading end part in a printing direction. SOLUTION: In the ink jet print apparatus, a manually inserted seal paper 32 having a layer changing physical properties irreversibly set to a print face is used for a means which prints images with use of an ink jet head capable of discharging ink. A right corner of a leading end part in a printing direction of the seal paper 32 is cut. When ink is set to the ink jet head to print, a margin of the print face is prevented from rubbing the head, so that images can be printed to the manually inserted seal paper 32. A large effect to the friction of the ink jet head which adversely affects an image quality is prevented.

Title: Hydraulic control device for belt type continuously variable transmission for vehicle
Inventor: KONO KATSUMI
IPC: B60W10/10
Filed: 1987-03-11
Abstract: PURPOSE:To reduce the power loss of an engine and prevent the deterioration of the driving performance due to the quick speed change by opening a relief valve and relieving the operating oil in a communicating passage to prevent the excessive pressure rise when the flow cross section area of a speed change control valve is expanded at the time of the quick speed change. CONSTITUTION:When the speed ratio variation (target speed ratio (e') - actual speed ratio (e))/(e) is large under the speed change state that the speed ratio (e) is quickly changed, the flow cross section area of a speed change control valve 46 is made large. When the flow cross section area of the speed change control valve 46 is large, the opening of a relief valve 108 is expanded, the pilot pressure applied to the first regulating valve 50 is reduced, because the first line oil pressure Pl1 is fed to a hydraulic cylinder 26 or 28 as it is when the flow cross section area of the speed change control valve 46 is expanded, thus the first line oil pressure Pl1 is prevented from being sporadically increased to the excessively high pressure. Accordingly, even when the flow cross section area of the control valve 46 is expanded at the quick change of the speed ratio, the first line oil pressure is regulated to the oil pressure necessary and sufficient for the speed change control.

IPC: H04B1/707
Filed: 1995-03-15
Abstract: PURPOSE: To obtain a spread spectrum communication system which can reduce the cost and circuit scale taking advantage of a spread spectrum communication system by a conventional delay multiplexing system and is applicable even when fading is large. CONSTITUTION: The transmitter of a spread spectrum communication system multiplexes and transmits an I signal generated by modulating data spread with delayed spread codes by a modulator 5 and a Q signal generated by modulating only the spread codes by a modulator 7 through a multiplexer 13. A receiver distributes the received signals into two by a distributor 23 and correlates them by a correlator 27 after making one distributed signal into an I1 signal of a base band to obtain an I2 signal. The other distributed signal after being made into a Q1 signal of the base band is correlated by a correlator 31 to obtain a Q3 signal which is delayed by a delay element 39. The I2 signal and Q3 signal are multiplied by a multiplier 40 and the resulting signal is demodulated by a data demodulating circuit 41 into data.
