Title: Both side printing method and printer
Inventor: SHIMA TOSHIHIRO
IPC: G06F3/12
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To improve the probability of normally completing both side printing by judging either of the surface side or rear side printing subject data is given priority for the image formation for each pair according to the data sizes, and forming an image of printing subject data of a larger data size prior to the other. SOLUTION: A printer 1 comprises a controller 2, an image forming portion 4 for converting printing data to an intermediate code, and an intermediate code memory 5 for storing bit image data. The image forming portion 4 produces intermediate codes for surface side printing and rear side printing per band and stores them successively in a memory 5. A monitor portion of the controller 2 monitors whether or not an error is generated in the code formation or storage. If an error is not generated, ordinary both side printing is conducted. If an error is generated, the monitor portion stops the code formation and storage of the pair and updates the set printing order of the surfaces to become opposite by a printing order switching portion. If the error is solved as a result of the retrial, both side printing is conducted.

Title: Speed controller of induction motor
Inventor: MASAKI TAKANOBU
IPC: H02P23/07
Filed: 1984-06-25
Abstract: PURPOSE:To preferably control an induction motor without disorder in the characteristic of a speed control system by applying a voltage to the motor to flow a current when the motor is stopped, operating the secondary resistance value from the voltage and the current and correcting parameter value. CONSTITUTION:When a cage 10 is stopped, a voltage is applied from a voltage supplying circuit 112 through a converter 113 to an induction motor 6. The current and the voltage at this time are detected, input to the secondary resistance value calculator 114 to calculate the secondary resistance value and to correct parameter value, thereby generating a signal in response to the ratio Rr/Rr0 of the true value Rr of the primary resistor and the parameter value Rr0. Thus, since the value Rr0 of the secondary resistor is corrected only at the stopping time of the cage 10, the fixed secondary resistance correcting value is merely used as parameter while the cage 10 is elevating. Accordingly, no disorder may be applied to the characteristic of the speed control system of an elevator by the correcting circuit.

Filed: 1999-05-11
Abstract: PROBLEM TO BE SOLVED: To prevent a smothering miss by setting shafts of a specific number of clubs having lofts of specific values at the same length and the same weights respectively within specific permissible ranges. SOLUTION: The lengths and head weights of the shafts of >=3 pieces of the clubs having the lofts of 35 to 65 deg. are made the same. At this time, the permissible range of the length is specified to >=12 mm, more preferably within about 8 mm and the permissible range of the head weight within 9 g, more preferably within about 6 g.

Title: Data bus circuit for microcomputer
Inventor: SATO AKIHIRO
IPC: G06F13/36
Filed: 1990-05-21
Abstract: PURPOSE:To evade the runaway of a microcomputer by separating electrically a program loading part from an external data read/write part when the program load timing is detected. CONSTITUTION:The timing when a data bus DB is divided into a program loading part and an external data read/write part, i.e., the timing when the analog switches 50a and 50b are actuated is identical with a period when a signal is outputted from an output terminal TO of a decoder 40. Furthermore this period is coincident with a period when a CPU 10 selects a ROM 20 and loads a program. Meanwhile the CPU 10 reads the data disturbed by the noises instead of the normal data to cause the runaway when the line noises are superposed on the bus DB. In this respect, the switches 50a and 50b separate electrically the external read/write part of the DB where the noises are superposed only in a loading period from the program loading part of the DB where the program data are loaded. As a result, the runaway of the CPU 10 can be prevented.

Abstract: PROBLEM TO BE SOLVED: To obtain an image signal of high resolution by classifying input image signal in block units in stages according to an activity code. SOLUTION: As for an SD(standard resolution) image signal S1 inputted to an up converter, the activity classification part of a classification part 12 determines a threshold according to a dynamic range DR, and sets a tap pattern corresponding to the characteristics of the dynamic range DR of the SD image signal S1 among three kinds of spatial class tap pattern (wide-area tap pattern, standard-area tap pattern, and narrow-area tap pattern) according to a class code c0 obtained as the result. Thus, the class tap pattern on which the dynamic range DR characteristics of the input SD image signal are reflected is set. According to a class code C1, the number (k) of requantized bits of each tap for spatial class classification is varied according to the class code c1 to switch the level resolution of the tap.

Abstract: PURPOSE:To enable mixture consisting of cadmium oxide and cadmium metal to be easily  manufactured at a low cost by evaporating cadmium metal in an atmosphere containing a  regulated amount of air so as to make part of the said cadmium metal to remain unoxidized. CONSTITUTION:After cadmium metal contained in a crucible is heated to 800-850 deg.C in an  atmosphere contained in a tube, the pressure of the tube is regulated to around several hyndreds mm.Hg by actuating a suction blower so as to obtain mixture consisting of cadmium oxide and cadmium metal. Next, 100pts.wt. of thus obtained mixture is kneaded with 0.5pts.wt. of a  tackifier such as polyethylene or methylcellulose and 30pts.wt. of water so as to make a pasty  active material, and the pasty material is applied to both surfaces of a nickel-plated perforated  iron plate before being dried. After that, the iron plate coated with the active material is  pressed with a pressure roller so as to adjust its thickness to a given value, and is cut into a  given dimension, thereby obtaining a cadmium electrode plate for a nickel-cadmium battery. A  sealed nickel cadmium battery is constituted by interposing a non-woven-fabric separator  made of nylon or the like between thus obtained negative cadmium plate and a positive nickel  plate, rolling the stacked body into a coil-like shape, and inserting the coil-like body into a  cylindrical nickel-plated can before electrolyte is poured into the can and the battery is sealed.
