Title: Manufacture of coil spring
IPC: B21F35/00
Filed: 1992-03-21
Abstract: PURPOSE:To easily correct the shape of the spring in a short time by pushing a key corresponding to a part to be corrected required times, preparing correction data, adding it to operation data and transmitting the result to an operation program. CONSTITUTION:When there is a part to be corrected, an operator pushes the key corresponding to the part by the times corresponding to the amt. to be corrected, that is, when the amt. to be corrected is equal to (n) times the correction unit, the operator pushes the key (n) times. In such a way, correction data of the value resulted from the number of push times is multiplied by the correction unit is prepared. Correction operation data is prepared by adding the correction data to the operation data. A comparing arithmetic whether the correction operation data is wrong data or not is operated, when it is not the wrong data, it is transmitted to the operation program and the correction operation program is prepared. A piece of spring is manufactured on trial based on the correction operation program, and when it is suitable to the target specification, the manufacturing process is executed. If the operation data is wrong, the warning is given by displaying the error, and the operator performs correction of the reverse direction until an error display lamp is turned off.

Title: Life warning circuit for thermal printer head
Inventor: KOMATSU AKIRA
IPC: B41J29/46
Filed: 1987-04-16
Abstract: PURPOSE:To inform the life of a head and to prevent a printing quality from being deteriorated by detecting the resistance value of the dot of the head at an upper limit thereof. CONSTITUTION:A com5 and a point A always communicate on a head terminal T, dot1 to dotn on the terminal T generate dot selection signal from a dot selector 10 by a dot selection command from a CPU 11, and select an AND circuit 8 from N1 to Nn. Thus, it communicates with B through an OR circuit 9. The points A, B are connected to points C12, D13. Here, when the initial resistance value of the head dot is Rh, this bridge is balanced under the condition of RhR2=R1R3, and a potential difference VEF between points E17 and F18 becomes zero. Since the VEF is the difference of the points E and F, it is represented by VEF=VE-VF. Then. an operational amplifier Op1(19) calculates VE-VF to obtain the VEF. Then, an operational amplifier Op2(20) compares the VEF with a reference voltage E2, and outputs a signal to G21 when the condition EEF>E2 is satisfied.

Title: Data transmission equipment
Inventor: NARUSE MAKOTO
IPC: H04L25/49
Filed: 1987-04-21
Abstract: PURPOSE:To improve mass production capacity, to simplify circuit constitution, and to lower manufacturing cost, by taking out digital data to be transmitted from a first circuit means as serial data, bit by bit, supplying it to a conversion means, converting it to a 180 deg. phase modulated rectangular wave signal, and inputting the signal to a second circuit means. CONSTITUTION:A shift register 14 responds to the rising timing of a clock pulse signal CK, and shifts the data of 9 bits in order, and changes it to bit- serial data, and inputs it to an Ex-OR gate 15 in order as data D0. And the data D0 is converted to and outputted as the 180 deg. phase modulated rectangular wave signal by the Ex-OR gate 15. The higher harmonic signal component of a conversion output signal CS is eliminated by a low-pass filter 17, and a transmission signal TS comparatively similar to a sine wave and of pseudo sine wave shape can be obtained. Thus, since the conversion of prescribed data D to be transmitted to the 180 deg. phase modulated rectangular wave signal is performed by one Ex-OR gate 15, the circuit constitution can be simplified and the profitability of miniaturization and making into an IC can be obtained.
