Title: Mold clamping apparatus
Inventor: UCHIDA MASASHI
IPC: B29C45/66
Filed: 1988-11-11
Abstract: PURPOSE:To shorten a mold clamping cylinder stroke and to reduce an anchoring space, in a double-toggle type mold clamping apparatus, by connecting the leading end part of the separate toggle link connected to a crosshead to the almost center part of the toggle link pivotally mounted on the side of a link housing. CONSTITUTION:When pressure oil is supplied to the rear chamber 8a of a mold clamping cylinder 8, a piston rod 9 advances and the stretching force is transmitted to the second toggle link 6b and the first toggle link 6a through the third toggle link 6c connected to a crossrod 7 and the toggle pin provided to the almost center part B of the second toggle link 6b. By this method, the first toggle link 6a is pushed and extended while a movable plate 3 starts advance movement. Further, the third toggle link 6c, the first toggle link 6a and the second toggle link 6b straightly extend and the movable plate 3 becomes a clamped state closing molds 4a, 4b. In this case, since a mold clamping cylinder stroke may be short by about 30% as compared with a conventional one, the total length of a clamping apparatus is shortened by about 15%, the clamping apparatus can be efficiently anchored in a narrow space.

Abstract: PURPOSE:To readily separate a polymer into several components differing in composition, crystallizing, etc. one another, by dissolving a crystalline polymer in a solvent on heating followed by being kept at lower temperatures to obtain a gelled product which is then subjected to extraction with a solvent under its refluxing state. CONSTITUTION:In the separation of a crystalline polymer such as propylene block copolymer into several components through sequential extraction, said crystalline polymer is dissolved virtually completely in a solvent (e.g. hydrocarbon compound, ester, ketone) on heating followed by being kept at lower temperatures for a sufficiently long time for the polymer to crystallize and separate out (normally for 24hr) to obtain a gelled product. This product is subjected to sequential extraction with a relatively low-boiling point solvent under its refluxing state, pref. under ambient - reduced pressure at temperatures below the melting point of said polymer.

Filed: 1993-10-19
Abstract: PURPOSE:To suppress the discharge of harmful components such as NOx to the utmost also at the changeover time of an air-fuel ratio from lean to rich or from rich to lean. CONSTITUTION:Whether the deviation between the present value and preceding value of a correction target air-fuel ratio coefficient is larger than '0' is judged in a step S4. At the time of the answer being affirmative, it is so judged that an air-fuel ratio has changed to rich from lean, and in the reverse case, it is so judged that the air-fuel ratio has changed to lean from rich. The first specified quantity LDKC and the second specified quantity DLDKC corresponding to each changeover time are computed in a step 5 to a step 8. The correction target valve opening LCMDM is computed (S13) on the basis of the basic valve opening LMAP and the valve opening correction value KEAF computed on the basis of the operating state of an engine, and the LDKC value, and an EGR valve is controlled on the basis of the LCMDM value. Hereafter, the DLDKC value is successively subtracted from the LDKC value to shift into normal exhaust gas recirculation control (S14 ...S16 S12 S13).

Title: Motor control system
Inventor: UTAGAWA TSUTOMU
IPC: H02P8/14
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To reduce wows and flutters and noises of a stepping motor by a method, wherein the drive power supply voltage level of the stepping motor is fixed and the voltage supply is turned on and off to practice the constant voltage control of the motor current, and a control mode is switched between a constant voltage control mode and a constant current control mode with predetermined timings, while the motor rotates. SOLUTION: When the level of an A/B* signal is H, the A-side of a switch 125 is closed to select a constant current control mode, and when it is L, the B-side is closed to select a constant voltage control mode. The current of a motor is converted into a voltage by a current detection resistor 111, and the voltage is compared with a current reference signal 105 from a CPU 101 by a comparator 113. When the voltage of the current reference signal 105 is higher than the voltage of the motor current signal 112, an on/off signal 114 whose level is H is outputted, and when it is lower, an on/off signal 114 whose level is L is outputted. If the constant current control mode is selected, a current at the time of motor driving is kept constant by turning on and off a switch 115.  When the constant voltage control mode is selected, the current can be kept constant by turning on and off a switch 118. Wows and flutters can be reduced, and the low cost control can be practiced by switching the control mode while the motor rotates.

Title: Precise feeding device
Inventor: MATSUI TAKAO
IPC: G05D3/00
Filed: 1985-12-20
Abstract: PURPOSE:To feed a member to be fed axially precisely at intervals of fine distance by providing a piezoelectric element which vibrates a guide bar for guiding the feed member axially to one end of the guide bar. CONSTITUTION:The 2nd piezoelectric element 35 on a carriage side is driven before the 1st piezoelectric element 25 on a guide-bar side is driven, so that clamping pieces 31 and 32 are so displaced as to come closer to each other. Consequently, a carriage 20 moves by fine distance together with the guide bar which moves finely in a feed direction. Then, the pulse voltage of the 2nd piezoelectric element 35 is ceased, the guide bar 24 is displaced finely as the piezoelectric element 25 contracts. At this time, the clamping pieces 31 and 32 generate no clamping force to the guide bar 24, so the carriage 20 stops at its current position because of its inertia even when the guide bar 24 is displaced in the opposite direction from the feed direction, so that it moves forth on the whole. Further, the carriage is moved back by cutting off the pulse voltage to the 1st piezoelectric element 25 after a pulse voltage is applied to the 2nd piezoelectric element 35.
