Title: Ph meter with self-diagnosing function
Inventor: TOU MASAHIRO
IPC: G01N27/26
Filed: 1984-03-30
Abstract: PURPOSE:To automate the judgement on the deterioration of a glass electrode with high accuracy and to enable alarming at an optional deterioration level by providing a function to add a means for detecting automatically film resistance within a converter circuit. CONSTITUTION:Inter-electrode liquid resistance clamps the potential of an electrode terminal RE to the reference potential COM of the circuit and acts as input resistance to receive the AC signal of an amplitude Vk from an AC generating circuit 3 via a capacitor C1. The AC component V0 in the output voltage is cut off of the DC component of a capacitor C3 and is then converted to a DC voltage V1 by a rectifying and smoothing circuit 5. On the other hand, a smoothing circuit 6 smooths the AC component V0 and takes out a DC component V0. The output passes through a temp. compensating circuit 7 which receives a measured liquid temp. signal Vt and calculates the pH value converted to a reference temp. and supplies a pH measuring output V2 to an output terminal 8. A temp. compensating circuit which receives the DC voltage V1 associated to film resistance Rg and the signal Vt and makes calculation is provided in addition to the above-mentioned circuit. An alarm circuit 12 which receives an alarm set voltage Vs and applies an alarm signal to a terminal 13 when V1<=Vs is also provided.

Title: Speed reducer
Inventor: ARIMOTO TOKUICHI
IPC: F16H7/06
Filed: 1988-03-17
Abstract: PURPOSE:To obtain a stable power transmission performance at a low cost by suspending a power transmission composed of a pair of three-piece sprockets between a drive sprocket and a driven sprocket. CONSTITUTION:Between a drive sprocket 1 and a driven sprocket 2, a power transmission composed of a pair of three-piece sprockets is suspended. In this case, the size number of a roller chain according to the number of sprocket teeth is suitably selected for performing a desired speed reduction. With this arrangement, it is possible to perform the speed reduction according to the sprocket teeth and obtain a speed reducer at a low cost in comparison with a motor provided with a conventional speed reducer. Since the drive sprocket 1 and the driven sprocket 2 are arranged on a line formed by connecting the first sprocket 3 to the second sprocket 4 of the power transmission, it is possible to prevent the speed reducer from being offset so as to obtain a stable power transmission performance.

Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To handle data other than control data with necessary minimum buffer capacity by providing a registering ID part storing the ID information of data to be received and a filtering part which performs comparison processing of an ID part of data on a transmission path with ID information stored in the registering ID part, etc. SOLUTION: A filtering device consists of a FIFO 1 for reception, a hardware filtering 2, a serial-parallel converter 3, a buffer 4 for registration ID and a serial line 5. The filtering 2 performs comparison about whether or not an ID coinciding with the ID part of received data from the converter 3 exists among registered IDs existing in the buffer 4. In the case of coincidence in the filtering 2, a registered ID number stored in the buffer 4 with a registered ID is written together in the FIFO 1 for the received data. Thus, the entire buffer capacity can be suppressed low regardless of the number of registered IDs.

The means 31 separates a loop composed of a transmitter 1 and a receiving resistance 5 working as a receiver from each other by means of a transistor (TR) 20 and switch 11 as occasion demands. When the switch 11 is turned off and the TR 20 is turned on, a loop working as a two-wire instrument is formed and, when the switch 11 is turned on and the TR 20 is turned off, a loop composed of the switch 11, transmitter 1, power source 19, and a resistance 22 and another loop composed of the resistance 5, a loop power source 4, a TR 17, and a resistance 18 are formed. The dummy outputting means 30 stores the current value of the loop working as the two-wire instrument just before the loop is separated by the means 31 after sampling and outputs the current as the dummy current value of the resistance 5 side loop. After the above-mentioned loop separation is made by means of the means 31, communication with the transmitter is carried on at the transmitter-side loop while the dummy output is given to the receiver at the receive-side loop. Thereno influence is given to the receiving current of the receiver during the communication.
