Title: Controlling circuit for arc welding voltage
Inventor: IWATA AKIHIKO
IPC: B23K9/06
Filed: 1985-05-30
Abstract: PURPOSE:To increase the welding quality by providing the steady error correcting circuit to eliminate the steady errors of welding voltage and welding target voltage and by deciding the welding current based on the outputs of this correcting circuit and error amplifier. CONSTITUTION:The difference Vepsilon in the welding voltage VO and welding aiming voltage VR is detected by providing an error amplifier 3. A steady error correcting circuit 9 and welding current setting circuit 10 are arranged by linking with the error amplifier 3. The welding current setting circuit 10 is formed by PWM modulation circuit 4 and adder 5. When the welding voltage VO is fed to the error emplifier 3, the amplifier 3 outputs the difference Vepsilon from the target voltage VR as Ves via the steady error correcting circuit 9, which is added to the output Vepsilon. The correcting circuit 9 stabilizes the control circuit by making the output Vepsilon always in zero by an integrator, etc. The welding voltage and current are thus allowed to coincide with the target value and the welding quality is increased because of the steady error being enabled to be eliminated.

IPC: G11B21/10
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic disk apparatus in which a head can be positioned with good accuracy in an arbitrary position in the radial direction on a disk by measuring the gain of a positioning control system with respect to the position of the head to find the relationship between the position of the head, and converting a position signal and an observed position signal into the precise position of the head. SOLUTION: A target position 37 is made to offset by every set value. A head is positioned in a measuring place inside a track pitch. In this position, an excitation signal 65 at a certain frequency is applied from a positioning-control-system open-real- gain measuring part 62, and the head is excited. Then, signals before and after the excitation signal is applied are measured. The amplitude ratio of the excitation frequency component of a measuring signal (1) 66 to the excitation frequency component of a measuring signal (2) 67 is calculated. After that, a prescribed parameter is decided in a position-signal nonlinear-amount-parameter decision part 63. By these processing operations, the relationship between the position of the head and a position signal is obtained, and the relationship can be converted into the precise position of the head.

Title: Reception clock interrupting detection circuit
Inventor: SAWA HANAE
IPC: H03K5/19
Filed: 1989-05-11
Abstract: PURPOSE:To detect clock interruption for a reception clock of any period and to set the detection accuracy of clock interruption optionally in response to a set threshold level by calculating a difference of a count between a received clock and a self-running clock, comparing a difference of the count with the threshold level and detecting the reception clock interruption. CONSTITUTION:A comparator 7 compares a difference signal SS of a subtractor 5 with a threshold level of a register 6 and when the difference signal SS of the subtractor 5 is larger than the threshold level ST, the comparator 7 discriminates it to be reception clock interruption. When the reception clock is interrupted, only a counter 2 counts a self-running clock CL 2 and since a carry signal SC to reset the counter is not outputted, a difference between counts of the counters 1, 2 is being increased. When the count of the counter 2 is larger than the count of the counter 1, the comparator 3 outputs a signal of '1' to a selector 4, which outputs a signal of '1' given to the input terminal from output terminals A, B as signals SA SB.

Title: Information processor
Inventor: NISHIYAMA MASAKI
IPC: G11B20/10
Filed: 1986-05-22
Abstract: PURPOSE:To shorten the total access time of an external storage device by processing write data which is rewritten within a specific time in an information processor without writing it in the external storage device. CONSTITUTION:A CPU 1 performs normal information processing and data writing control and a control means 3 cooperates under the data writing control. When a request to write new data is generated, the write address of the request is compared with the last write request address stored in the buffer 41 of a RAM 4. When the request is generated for the 1st time, data requested to be written and its write address are stored in the buffer 41. Write data to be rewritten within the specific time at a successive write request is not written on a flexible magnetic disk unit(FDU) 6, but transferred to the buffer 41. Then, the write data in the buffer 41 is read out and utilized as it is when necessary. Thus, the access time of the FDU 6 is shortened.

Title: Inflected metal vibrator
Inventor: KAWASHIMA HIROFUMI
IPC: H03H9/24
Filed: 1978-09-20
Abstract: PURPOSE:To obtain excellent frequency-temperature characteristics by reducing extremely the absolute value of the sum of the primary temperature coefficient of the Young's modulus of a metal vibrator and its primary linear expansion coefficient. CONSTITUTION:Metal tuning fork 1 with piezoelectric thin film 2 formed on its surface is supported at its base part by lead wires 3 and 4 as electrode terminals. Denoting the primary temperature coefficient of the Young's modulus of a material for vibrator 1 by E1 and its primary linear expansion coefficient by X1, a frequency variation rate is unrelated with a temperature with E1+X1=0, namely, when E1 and X1 are opposite in sign and equal in absolute value. By selecting the adequate composition of the material, X1 can be fixed between 4.9X10<-6> and 8.1X10<-6>/ deg.C and E1 between -10.1X10<-6> and -2.9X10<-6>/ deg.C and consequently ¦E1+X1¦ can be made less than ZX10<-6>. As a result, frequency variation ratio DELTAf/f is expressed by (I) [wherein t represents the temperature] and excellent frequency- temperature characteristics can be obtained.

Title: Battery-powered timepiece with mechanical display
Inventor: HARAKAWA MOTOTAKA
IPC: G04C3/14
Filed: 1978-09-20
Abstract: PURPOSE:To raise the efficiency of use of a battery, reduce the number of parts of a timepiece and increase its mass productivity, by altering the width of motor  driving pulses depending on the use or non-use of additional functions such as  alarm raising, time announcement and dial illumination. CONSTITUTION:The output of a quartz oscillation circuit 4 is frequency-divided at 5. A pulse is selected from signals T1, T2 of identical frequency but different pulse width, depending on the presence or absence of a switching signal to a pulse width change circuit 6. The selected pulse is applied to a motor output circuit 7 for a step motor 8 for driving hands. When a contact 10 of an alarm mechanism and a manual switch 9 are closed, an alarm output circuit 13 is driven by a signal of a timing circuit 11 and the pulse width change circuit 6 is caused to select a larger pulse width than usual. The width of driving pulses for the step motor 8 is thus increased.

Abstract: PURPOSE:To enable to stably perform an output control over a wide scope ranging from a low output to a high output by a method wherein the discharge gas pressure is changed in accordance with the required output. CONSTITUTION:A gas introducing port 8 and a gas exhaust port 9 are provided on the discharge tube 1 which is connected to a high-tension power source 3 and a constant current circuit 5. A gas cylinder 6 is connected to said gas introducing port 8 through a gas flow rate adjusting valve 7 and an exhaust pump 11 is connected to the gas exhaust port 9 through the intermediary of an exhaust flow rate adjusting valve 10.

Through these procedures, the desired photo output can be obtained in a wide scope ranging from a low output to a high output.
