Title: Static eliminator for film
Inventor: SATO HIROTA
IPC: G03B17/50
Filed: 1993-11-26
Abstract: PURPOSE:To obtain an inexpensive and small-sized static eliminator for film whose constitution is simple by providing a pair of conductive developing rollers and a static electricity transferring means. CONSTITUTION:When film 4 is carried while it is pressed by a pair of spread rollers 12 and 13, static electricity is generated on the surface of the film 4. In this case, since the rollers 12 and 13 and static eliminating brushes 17 and 18 are made of conductive material, the static electricity flows to the negative terminal of a sheet type battery 8, that is, a ground potential part through the rollers 12 and 13 and the brushes 17 and 18. The wirings of the brushes 17 and 18, the negative terminal 9 of the battery 8 and the ground potential part are made extremely short and thick so as to get low impedance. Thus, the static electricity generated in the midst of feeding the film is prevented from being charged by such simple constitution, the quality of a photograph is prevented from being deteriorated by the static electricity, and further influence exerted on the electric circuit of a camera is eliminated.

Title: Method for diagnosing corrosion of reinforcing bar or piping in concrete
Inventor: KAWASHIMA TAKESHI
IPC: G01N27/02
Filed: 1986-12-12
Abstract: PURPOSE:To perform the accurate diagnosis of corrosion, by a method wherein high frequency and low frequency AC currents are applied between a reinforcing bar and an electrode for diagnosing the corrosion of concrete and the real part values of respective AC impedances are calculated. CONSTITUTION:Two kinds of high and low frequency AC currents are respectively independently applied between an electrode 6 for dianosing the corrosion of concrete and a reinforcing bar 2 by an AC current applying apparatus 5. The voltage response between the reinforcing bar 2 and the electrode 6 at this time is monitored by an AC potentiometer 11 and converted to AC impedance from the phase shift of an input signal and an output signal and the ratio of the amplitudes of both signals by a frequency response analyzer 12. Then, the real part of the AC impedance is used as the factor of corrosion diagnosis. Further, the real part value when the high frequency current is applied corresponds to the ohm resistance between the electrode 6 and the reinforcing bar 2, and, further, the real part value when the low frequency current is applied corresponds to the sum of the ohm resistance between the electrode 6 and the reinforcing bar 2 and the resistance relation to the corrosion speed of the interface of concrete 1 and the reinforcing bar 2. Therefore, the real part value at the time of high frequency is subtracted from the real port value at the time of low frequency and, when the value obtained is large, corrosion-free condition is judged.

Abstract: PURPOSE:To increase transmission speed of a data and a control signal, and to quickly control an indoor environment to make a comfortable environment, by transmitting plural bits in synchronizing with the frequency of a power source of an air conditioner. CONSTITUTION:When a power source switch of an air conditioner is turned on, a controller 10 of an indoor machine outputs data, a control signal, and a serial signal of, for instance, 8 bits (01101001), corresponding to a set value which is set by an operation switch by a timing of a synchronizing signal pulse, to a controller 11a. On the other hand, a controller 11 of an outdoor machine converts its serial signal (01101001) by a timing of the synchronizing signal pulse and inputs it. In such a way, between the controllers 10, 11 of the indoor machine and the outdoor machine, the serial signal of plural bits is sent and received by a timing of a synchronizing signal pulse generated by synchronizing with a frequency of a power source. Accordingly, the transmission speed between the indoor machine and the outdoor machine can be increased. In such a way, a compressor, etc., of the outdoor machine can be allowed to respond quickly, and the indoor environment can also be controlled quickly.

IPC: H04B7/26
Filed: 1991-10-17
Abstract: PURPOSE:To judge the distance and direction to some degree even when a transmitter and a receiver are parted by a prescribed distance or over by making a 1st notice when a reception sensitivity reaches a 1st specified value or below and making a 2nd notice based on a 2nd specified value. CONSTITUTION:A signal including identification information is sent from a transmitter 1. When the reception sensitivity to the transmission signal reaches a 1st specified value or below, a notice means 40 such as a buzzer generates a notice sound to inform that the transmitter is far away by a prescribed distance or over. Simultaneously, a sensitivity changeover means 41 switches the reception sensitivity to a 2nd specified value. Then the notice means 40 implements notice operation such as reduction of buzzer tone ring interval in response to the reception sensitivity based on the 2nd specified value. Thus, the distance and direction are judged to some degree.
