Patent JP-H0218021-A (JP)
Title: Forming core and temperature controlling method thereof
Inventor: YAMAGUCHI HIROSHI
IPC: B29C45/26
Filed: 1988-07-07
Abstract: PURPOSE:To apply nearly uniform forming pressure to the whole formed item and consequently make it possible to obtain the favorable shape of the item even when locally ununiform cooling speed due to ununiform thickness develops by a method wherein the shape of a cavity, which is produced by material made of shape memory alloy, is adjusted by controlling the temperature of the material. CONSTITUTION:A cavity 2 is produced by the opposed surfaces of forming cores 1a and 1b, in each of which a temperature controlling groove 3 circulating heating medium for controlling temperature is produced. During the injection and filling processes, the cores 1a and 1b are held at about 100 C and have cross-sectional forms represented by solid lines 8a and 8b due to their shape memory actions. If the shapes of the cores are held unchanged, no proper pressure is applied to the central part of the resin, which is filled in the cavity at high temperature, resulting in developing sinking. In order to prevent said sinking from developing, as the cooling of the resin proceeds, the cross-sectional forms of the cores 1a and 1b turn into the forms of the desired formed item represented by broken lines 9a and 9b at about 85 deg.C due to the shape memory actions of the cores. As a result, nearly uniform forming pressure can be applied to the whole resin and consequently a formed item having a favorable form without sinking can be obtained.

Title: Media sheet carrying control method
Inventor: YAMASHITA TSUNEHIRO
IPC: G03B27/58
Filed: 1990-06-27
Abstract: PURPOSE:To simplify a device and to curtail cost required for the device without necessitating such a large torque as the time of rewinding a media sheet by executing the rewind processing of the media sheet after finishing an image forming processing, by pulling it back to a buffer part in a first stage, and rewinding it a supply shaft in a second stage. CONSTITUTION:When an image forming processing is finished, a rewind processing of a media sheet is started. A supply shaft 1a is in a lock state, and while take-up shaft is being energized in the reverse rotary direction, a buffer roller 4a moves in the direction as indicated with an arrow A. As a result, the media sheet is drawn out of the take-up shaft 1b, and stocked in a buffer part 4. This operation is continued for a t1 time, and during this time, the media sheet of length corresponding to a distance between an exposure part P1 and a pressure developing part P2 is stocked in the buffer part. Subsequently, this time the take-up shaft 1b is locked, and while the supply shaft 1a is rotating in the reverse direction, the buffer roller 4a is moved in the direction as indicated with an arrow B for a t1 time. In such a way, the media sheet of a position stocked in the buffer part 4 is rewound to the supply shaft 1a.

Filed: 1988-07-07
Abstract: PURPOSE:To improve easiness in detection and economy in equipment by forming a cavity part where substance housed in a tank does not enter in a part of the tank and varying a volume of the cavity part. CONSTITUTION:A volume changing mechanism 33 is set in the tank 3 and the volume V2 of the cavity part in the tank 3 is changed by said mechanism 33. A pressure accompanied with said change is converted into an electrical signal by a pressure detector 34 and supplied to a low pass filter 45 and a band pass filter 37 which are connected in series. The static absolute pressure in the tank 3 is detected by the filter 45 and a frequency same to the driving frequency of the mechanism 33 is set as a central frequency, then pressure changing amount equal to volume changing amount is detected by the filter 37. The maximum value of the pressure changing amount is detected by an amplitude detector 39. Thereafter, an output from the filter 45 is divided by an output from the detector 39 with the aid of division unit 40. The value obtained by the division becomes the volume V2 of the cavity part in the tank 3 and the volume VL of liquid 4 can be obtained by subtracting said volume V2 from the total volume VT of the tank 3 with the aid of a subtraction unit 41.

Abstract: PURPOSE:To certainly and quickly obtain an electrolytic water with an objective pH value by applying a predetermined electrolytic voltage set corresponding to the objective pH value and calculating the deviation to the objective pH value at a point of time when the output obtained from a pH sensor becomes stable to determine the electrolytic voltage to be applied. CONSTITUTION:When water is selected in an operation display part D, the application of electrolytic voltage to an electrolytic cell 2 is started by the sensing of a water stream with a flowmeter 66 and the pH value of electrolytic water is obtained from a pH sensor 7 by a control circuit C and electrolytic voltage is feedback-controlled corresponding to a selected level so as to become a objective pH value. At this time, when the objective pH value is set to pHM, the application of the voltage Vn set corresponding to objective pH value is kept until the output obtained from the pH sensor 7 becomes stable. Then, the deviation >=ApH between a pH value pHA and the objective pH value pHM is calculated at the point of time when the output from the pH sensor 7 is stabilized and the voltage Vn corresponding to the deviation >=pH is calculated from a voltage-pH characteristic table to control the supply of a current.

Abstract: PROBLEM TO BE SOLVED: To provide a guide pin holding mechanism for printed circuit board inspecting apparatus capable of making it difficult for the part between a guide pin and a guide pin plate to produce a backlash. SOLUTION: Being kept in contact with a top surface P1, a large-diameter part 25 is held with a fixing pipe 17 having the same diameter as the outside diameter d1 of the large-diameter part 25.
