Title: Injection/compression molding method
Inventor: HAMADA HAJIME
IPC: B29C45/80
Filed: 1985-05-08
Abstract: PURPOSE:To prevent the generation of molding inferiority, by automatically varying mold clamping pressure through an operation mechanism so as to correspond to the set value of an injection speed changed in a multistage fashion during an injection process. CONSTITUTION:When mold clamping pressure is controlled corresponding to an injection speed changed in a multistage fashion during an injection molding process, the position of a screw 1 is detected by an injection ram position detector 14 to be compared with each of the set positions S1-S4 preset to an injection speed change-over/ position setting device 12 by a comparator 16. An injection speed is controlled according to the order of the injection speeds V1-V4 set to an injection speed setting device 11 by the detection signal from the comparator 16 and the set value of an injection speed setting device 11 is successively inputted to an operation apparatus 35 and a servo valve 32 is acted by a mold clamping pressure order signal and the hydraulic pressure in a mold clamping cylinder 10 is varied to control the mold clamping force in a mold cavity. Because mold clamping pressure is lowered when the injection speed is fast by this method, the gas in the mold cavity is easily expelled by a filled resin and the surface-scorching of a molded product can be prevented and the surface property thereof can be enhanced.

Inventor: KONDO KASHIO
IPC: G06K7/00
Filed: 1997-04-16
Abstract: PROBLEM TO BE SOLVED: To accurately read a mark by deciding that there is a mark at a mark entry part when the density of the read mark entry part is larger than a specific threshold value, and updating the threshold value into a new threshold value which is the mean value of the density of the decided mark entry part and the threshold value used for the decision. SOLUTION: A format of a mark, an initial value of the threshold value, an update unit of the threshold value, and a limit value of thickness are set. Then a mark entered into a form is read by a scanner 11 and a microprocessor 13 calculates the density of each mark and decides whether the calculated density is larger than the threshold value to make a 'mark presence' decision when the density is larger than the threshold value, thereby judging whether or not the update period of the threshold value has come. When so, the mean value of the current threshold value and calculated density is calculated and used as a new threshold value. After all marks are read, discriminated and decided mark data are outputted and the process ends.

Title: Cap of writing utensil
Inventor: MATSUMOTO KAZUAKI
IPC: B43K23/08
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To prevent a seal sleeve from coming off the cap even in the case where it is joined with the tip end of a shaft by inserting the seal sleeve in the inner sleeve of the cap, engaging the flange of the seal sleeve to the opening- step part, mount-fixing a fixture sleeve thereon in the cap, and holding the seal sleeve by the inner sleeve and fixture sleeve. SOLUTION: When a cap is mounted on the writing utensil main body, a seal sleeve 15 consisting of elastic rubber or the like is close-contacted with the tip end outer peripheral surface of a chip support by its inside opening periphery 20, and by being close-contacted in contact-pressed relation onto the end part of a mouthpiece and end surface 25 of the seal sleeve 15, the opening part of an air groove is closed.  Thus, the seal sleeve 15 comes in close contact with the tip end outer peripheral surface of the chip support and the end part of the mouthpiece with the result that adhesive force exerts the member through self-adhesiveness of the seal sleeve 15; even if the seal sleeve 15 is press-fitted in the inner sleeve 14, it comes off the inner sleeve 14 due to its joint to the shaft side as the cap is detached; however, the flange 16 of the seal sleeve 15 is engaged with the fixture sleeve 18 so that it never comes off the inner sleeve 15.

Title: Valve control device of internal combustion engine
Inventor: KANEHIRO MASAKI
IPC: F01L13/00
Filed: 1989-04-19
Abstract: PURPOSE:To reduce the quick rise of the engine torque generated at the recovery by decreasing the engine output synchronously with the recovery of valve lift characteristics when it is detected that the excessive slip of driving wheels is decreased. CONSTITUTION:A TCS(driving wheel slip detection)-ECU 20 detects the excessive slip state of driving wheels. An ENG-ECU 5 controls a solenoid valve 26 in response to the output of the TCS-ECU 20 and performs the valve timing switching control of the suction valve and the exhaust valve of an internal combustion engine 1. When it is detected that the excessive slip of driving wheels is reduced based on the output of the TCS-ECU 20, the ENG-ECU 5 recovers the valve timing. The air-fuel ratio of a mixture is made lean synchronously with it, thus the output of the engine 1 is decreased. The quick rise of the engine torque generated when the valve timing is returned to the ordinary state after the excessive slip of driving wheels is suppressed can be reduced.

Abstract: PURPOSE:To assure the stable and continuous operation of a vacuum pump maintaining the normal wafer holding force after starting operation by a method wherein a valve is provided on the specified part of fine communicating pipes from respective suction pores of wafer holders to the vacuum pump. CONSTITUTION:When a wafer holder 11a is loaded with a wafer, if a vacuum pump is started by output of 100 i.e. 760 mmHg for suction, the lower end of a cylinder end 23a and a step difference 20ab are pressure welded with sufficient pressure to maintain the normal specified pressure in the lower part of a valve 22a in a vacuum chamber 15a, likewise maintaining the normal specified pressure in respective vacuum chambers 15b-15d of wafer holders 11b-11d. Next, when the wafer holder 11a is loaded with the first wafer 2, the wafer 2 covers the suction pores 12a to exhaust the vacuum chamber 15a by a vacuum pump through a slot 25a of cylinder end 23a above the valve 22a in the vacuum chamber 15 while the valve 22a is lifted upward by the overcoming pressure of a coil spring 21a lifting up the valve 22a to make the pressure above the valve 22a abruptly reach the pressure of vacuum pump output by lifting the valve 22a. Through these procedures, the wafer 2 can be held without fail while keeping the wafer holders 11b-11d unchanged.
