Title: Electronic weighing apparatus
Inventor: NAGANE YOSHIKAZU
IPC: G01G7/04
Filed: 1997-08-01
Abstract: PROBLEM TO BE SOLVED: To obtain an electronic weighing apparatus which comprises an automatic calibration function using a built-in weight and whose calibration is performed just enough. SOLUTION: The relationship between a weight display Wp and a temperature T is measured in advance by temperatures in many points, and a measured result is stored as a curve. In addition, the maximum allowable error em of the weight display Wp is set, and a calibrating operation is performed at a temperature T1 (a reference temperature TQ1). While the reference temperature TQ1 in the first calibrating operation is used as a reference, temperatures TH1, TL1 in which the maximum allowable error em is obtained are set and stored on the basis of the maximum allowable error em and the curve. A temperature detecting device is calibrated when the measured temperature T becomes the calibration temperature TH1 or TL1.  In addition, the calibration temperature TH1 or TL1 which is calibrated is used as a next reference temperature TQ2, and a next calibration temperature TH2 or TL2 is set and stored on the basis of the maximum allowable error em and the stored curve in the same manner. By performing this procedure sequentially, a calibrating operation is surely performed just enough within the maximum allowable error em.

Title: Constant speed running device for automobile
Inventor: KAWABATA WATARU
IPC: F02D29/02
Filed: 1988-09-01
Abstract: PURPOSE:To prevent automobile speeds from being reduced after a set switch determining a stored speed is actuated by driving an actuator provided with great duty for a definite period of time set in advance at the time of switching on. CONSTITUTION:When a set switch 3 is turned on during running with a pedal depressed, a processing circuit 1 allows the duty for control signals which are applied to a control valve solenoid coil 55 to be 90% during the time W1 from t1 to t2. Then, when switch-over is made from 'on' to 'off', the duty for the control signals which are applied to the solenoid coil 55 is kept on to be 90% during the time W2 from t3 to t4 so that control is executed in such a way that the control position of an actuator corresponds to the opening of a throttle valve 19 equivalent to the stored speed of an automobile. Change in the control position of the actuator 14 therefore starts displacement simultaneously when the switch-over of the set switch 3 is made from 'on' to 'off', while eliminating the delay in response by the actuator 14, thereby making it possible to make a reduction in automobile speeds small to a lesser extent immediately after actuation.

Title: Method for preventing rust after dew condensation or wetting with water
Inventor: TAKAHASHI TOSHIAKI
IPC: C23F11/02
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To impart high rust preventing power by rapid treatment even after dew condensation or wetting with water and to enable easy application to a product or a process in which oil cannot be used by sprinkling a volatile rust preventing liq. prepd. by mixing a rust preventing oil with a volatile corrosion inhibitor on the surface of a metal exposed to dew condensation or wetted with water. SOLUTION: A rust preventing oil is mixed with a volatile corrosion inhibitor based on N-cyclohexyl-cyclohexylamine, etc., a soln. of an alcohol such as n-propanol and a non-oil rust preventing soln. such as water to prepare a volatile rust preventing liq. This volatile rust preventing liq. is sprinkled or sprayed on the surface of a metal exposed to dew condensation or wetted with water. The components of the volatile rust preventing liq. dissolve in water produced by the dew condensation or in the wetting water to convert the water itself into a rust preventing liq. The corrosion inhibitor in the rust preventing liq. coats the surface of the metal in the form of a film and rapidly produces its rust preventing effect. Since water functions as a rust preventing liq., a high rust preventing effect can be maintained even in a damp place liable to dew condensation.

Title: Method and apparatus for injection molding foamed product
Inventor: KIKUCHI HIDEO
IPC: B29C45/20
Filed: 1986-09-19
Abstract: PURPOSE:To inexpensively control a foaming thereby to manufacture a foamed product having a preferable skin layer by foaming a foamable material by a frictional heat generated when the material passes an injection nozzle. CONSTITUTION:A foamable material is charged in a cylinder 11. When the material is introduced to the midway of a passage 17 of a nozzle tip 15, a screw 12 is moved forward, and the material of the quantity responsive to the forward stroke is injected. When the material passes very narrow second passage 17b, a frictional heat is generated, and it raises to a foaming temperature or higher. As a result, the material is foamed in the passage 17b of the tip 15. Since it is high pressure, foams are small. The foamed material is introduced into a cavity 27 at a high speed, cooled and solidified. Since the material becomes low pressure in the cavity 27, the foaming is reactivated to enlarge the foams. Thus, a foamed product 42 composed of a skin layer 44 having small foams and a cushion layer 43 having large foams is obtained.
