Title: Electromagnetic induction communication system
Inventor: YAMADA TORU
IPC: A61B5/00
Filed: 1991-09-20
Abstract: PURPOSE:To provide the electromagnetic induction communication system which can receive the electromagnetic induction signals of the same frequency transmitted from plural transmitters by one receiver. CONSTITUTION:When the output of step signals is detected (step A1), it is judged whether the electromagnetic induction signals are received from a pulse signal transmitter or not (step A2), and when those signals are received, transmission is waited for 5msec so as to preferentially transmit signals from the pulse signal transmitter (step A3). When the electromagnetic induction signals are received from the pulse signal transmitter (step A5) just after the step signals are received (step A4), the transmission of step signals is waited for 5msec (step A6) because the step signals transmitted just now are made invalid, and the step signals are transmitted again (step A7).

IPC: B42D9/04
Filed: 1993-09-29
Abstract: PURPOSE:To prevent accompanying page turning by providing a mechanism for preventing occurrence of double turning due to vibration caused by touching a paper face to be turned up, in a device having a page change roller which touches in a rubbing way a paper face to be turned of a brochure, etc., so as to change the page of the brochure. CONSTITUTION:When a passbook is conveyed on a paper pan 1 and stopped at a specific position, a page change roller 4 is rotated clockwise and begins touching a paper face to be turned. By the rotation of the page change roller 4, the paper face to be turned is buckled and turned upward. When the paper face to be turned touches a vibrating bar 3, it receives the vibration force of the vibrating bar 3 vibrated by a vibration source 7. Then, the touch of the paper face to be turned and a paper face of a paper which is going to be turned with the said paper is weakened. When the buckling resisting force of the paper face being turned in an accompanying way exceeds the frictional force, the accompanying paper face is returned by itself. Thus, a failure in turning pages, where a plurality of pages are turned at a time, is prevented.

Title: Contact type thermometer
Inventor: YAMANAKA KAZUO
IPC: G01J5/02
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To eliminate the resetting of emissivity depending on the kind of substance to be measured or surface condition of measuring parts so as to measure the temperature accurately in a short response time. SOLUTION: When a contact temperature sensing part 2 on the tip end of a probe 4 is brought into contact with a desired measuring part of an object to be measured, a heat in the object to be measured is conducted to the part 2 and an infrared ray is radiated from the back surface of the part 2 through the probe 4. Since it is detected by an infrared ray sensor 11 for temperature measurement, the measured temperature is determined as a temperature of the object to be measured if a thermal balance is established between the part 2 and the object to be measured. At this time, since thermal conduction is generated only between the part 2 and the object and it is not generated between the part 2 and the infrared ray sensor, the temperature of the object can be measured in a short time without time-lag.  Further, no resetting of emissivity is required at every measurement depending on the kind of substance to be measured by setting the emissivity of the part 2 in advance.
