Title: Electronic pedometer
Inventor: TASAKA ISAO
IPC: G06M7/00
Filed: 1987-06-15
Abstract: PURPOSE:To easily recognize the motion of the user of an electronic pedometer and, at the same time, to improve the accuracy, by separately counting and storing the numbers of walking steps and running steps. CONSTITUTION:Detection signals which are the output of a running/walking sensor 21 are selectively supplied to a blind zone processing circuit 24 for walking or blind zone processing circuit 25 for running in accordance with the operation of a running/walking switching button 23 operated by means of a switching circuit 2 and become signals shaped to one pulse per one step of running or walking. Since the optimum blind zone time can be set in corresponding to walking or running in such a way that a longer blind zone time t1 is set for walking because chattering contained in the output signal of the sensor 21 is relatively slow and longer in the case of walking and a shorter blind zone time t2 is set for running because the chattering contained in the output signal is relatively fast and shorter in the case of running, the detecting accuracy of this pedometer for running and walking is improved.

Title: Device and method for judging kind of material to be heated by induction heating cooker
Inventor: KIMU JIYON TAE
IPC: H05B6/12
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To shorten the time for judging kind of the material to be heated by judging whether a material to be heated is a small load or not, or judging whether a container is a magnetic container or a non-magnetic container in the condition that the frequency is fixed. SOLUTION: When the operation is started, a control unit 5 selects the judgment frequency, and outputs the switch control signal CS2 for operating a heating unit 20. When the current of an ordinary power source AC is detected and the corresponding voltage Va is input to the control unit 5, the control unit 5 reads this voltage value Va, and in the case of the voltage value Va at 1.2V or less, the material 3 to be heated is judged as a small load, and the drive of an inverter INV is stopped.  In the case of the voltage value at 1.2V or more, the input voltage value Vb is read out and judged whether the input voltage value Vb exceeds 1.8V or not, and in the case of the input voltage value at 1.8V or less, a judgment whether the voltage value Vb exists in a range at 0.75-1.0V or not is performed, and in the case of yes, the material 3 to be heated is judged as a strong magnetic container, and a switch SW is maintained in the ON-condition, and the strong magnetic container is heated by a magnetic mode.

This causes a printing ribbon to be located in a second stage switching position (for example: a block color zone). In the case of the electromagnet 30 being excited in the condition described above, a lock lever B24 rotates counterclockwise, and the printing ribbon, resultantly, is placed in a third  stage switching position for positioning.

Title: Pressure limiting device of wave power converter
Inventor: ISHII SHINICHI
IPC: F03B13/14
Filed: 1984-07-20
Abstract: PURPOSE:To correctly control the pressure of a wave power converter for a long time by connecting an air chamber to the atmosphere with a communicatin passage having a reservoir section and communicating the air chamber to the atmosphere when the pressure in the air chamber becomes the predetermined pressure or higher. CONSTITUTION:Liquid levels LA, LB of the first and second conduits 5a, 5b of a pressure limiting device 5 are varied up and down in response to the change of the air pressure in an air chamber 2. When the air pressure is within a nornal pressure range, these conduits are sealed so that the air in the air chamber is not released to the outside through the U-shaped conduits. When a large wave surges and the air pressure in the air chamber 2 is abnormally increased, the liquid level LA is pushed down to reach the lowest level l3, and the air in the air chamber 2 is released into the atmosphere through the second conduit 5b, thus the normal pressure can be maintained.

Title: Back hoe
Inventor: MIURA TAKANORI

Filed: 1993-06-22
Abstract: PURPOSE:To obsorb assembling error, by providing a restraint face with a specified distance at the outside of the driver's seat to prevent the bucket from entering into the driver's seat and letting it memorize the specified position of bucket to partly correct the restraint face. CONSTITUTION:Restraint faces A1, A2 separated by a specified distance from the outer frames 29, 30 of the driver's seat and the control range B1 are input in a controller. Next, the controller always calculates the position of bucket 6, the transferring direction and the transferring speed in accordance with the detected value of an angular sensor. When the bucket 6 enters in the range B1, the speed is regulated to reduce it and when it reaches the restraint faces A1, A2, it is forced to stop. When the actual position of the bucket 6 is different from a preset position due to the assembling error and the proper error of an angular sensor, the bucket 6 is operated to the required position so as to let it memorize the position. Based on this position, respective preset figures of the controller are computed and corrected. In this way, the bucket can stop at a correct specified position and hence, safety and workability are increased.

Title: Dynamic type conversion system for data
Inventor: SUGINO KAZUHIRO
IPC: G06F12/00
Filed: 1985-07-10
Abstract: PURPOSE:To avoid the change of a program despite the change of the data structure by giving accesses to the record for each data and editing the record again after conversion of the attribute and the length of data. CONSTITUTION:When the wages of employees are calculated, an operator sup plies a command through a keyboard 2 for calculation of wages. A command processor retrieves a group of commands registered to a disk 6d to decide a wages calculation command and loads the information on the command to a main storage 4 to prepare for calculation of wages. Then the command proces sor delivers the external interface specifications defined in the information on the wages calculation command to a data handling system in the form of a parameter and gives an indication to the handling system to receive the data needed for calculation for each record. The field information on the table is different from the external interface information on the wages calculation com mand. Thus the data is edited after the attribute, the length and the type of the data are converted for each field to the extracted record.
