Title: Load shorting protection circuit of switching regulator
Inventor: KONO KAZUTAKA
IPC: H02H7/12
Filed: 1988-08-16
Abstract: PURPOSE:To eliminate heat generation and voltage drop and to curtail the cost by stopping the switching operation with the reference voltage of an output voltage detection means forcedly reduced to negative potential. CONSTITUTION:If a load 60 is shorted by some cause or other, short circuit current will flow to the secondary side of a DC-DC converter 20 and the charged electric charge of a capacitor C2 of a load shorting detection circuit 50 is discharged via C2(+) - earth resistances R2 - diode D3 - C2(-). On that account, the (+) input terminal of a differential amplifier M1 drops to a negative potential not higher than the earth potential, while detected voltage V0 of a (-) input terminal is held for necessary hours by the electric charge at the capacitor C3 and the differential output voltage of a differential amplifier M1 increases remarkably. When this differential output voltage is added to a pulse width control circuit 411, it controls the output voltage VOUT to be the value of reference voltage Vref which is a negative potential not higher than 0V, so that the pulse generation operation is stopped and at the same time the switching element 212 is also stopped.

Title: Spectrum processing method for time-of-flight mass spectrometer
Inventor: NUKINA YOSHIHIRO
IPC: G01N27/62
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To provide rapidly a mass spectrum that is not affected by the response of a high-voltage pulse circuit or the aberration of a mass spectrometer by measuring a single mass spectrum and a multi-spectrum and finding a device function for duplicating the multi-spectrum in advance. SOLUTION: In a table setting mode, a calculation by means of Fourier transformation is performed by a Fourier transformation part 13 based on a single mass spectrum obtained from a single pulse and one superimposed multi-mass-spectrum obtained from an n-pulse train by the use of a standard sample or the like. Then, a device function arithmetic processing part 14 memorizes them, calculates a device function and stores it in a device function table 15 as the device function at the time of inverse convolution. In a measurement mode, a reverse Fourier transformation is performed through the device function table 15 and a reverse Fourier transformation part 16 in relation to the multi-mass-spectrum of a sample measured by generating ion pulses as in the case of the standard sample and thereby, the single mass spectrum is found and stored in a spectrum storing part 17.

Title: Light-emitting diode and its manufacture
Inventor: HOSOI YOJI
IPC: H01L23/00
Filed: 1988-08-17
Abstract: PURPOSE:To enhance the efficiency of coupling to an optical fiber by a method wherein light which is emitted at a light-emitting part constituted of a P-N junction is radiated from a side face and the side face is formed to be of an arc shape protruding in a horizontal direction with reference to a semiconductor substrate. CONSTITUTION:One part of a substrate 10, a first clad layer 11, an active layer 12, a second clad layer 13 and a cap layer 14 are etched to be a rectangular shape whose area is larger than an N-side electrode 15; a light-emitting part 16 is formed; a cross section in a horizontal direction of one end face 16a for light radiation use on its one side face is formed to be of an arc shape, i.e., of a convex lens shape. When a positive voltage is applied between the N-side electrode 15 and a P-side electrode 17, a small number of carriers are injected into a P-N junction at the clad layer 11, the active layer 12 and the clad layer 13 constituting the light-emitting part 16; when the carriers are jointed again, light is radiated from the end face 16a. Since the end face 16a of the light-emitting part 16 is formed to be of the convex lens shape, a spread of the radiated light is reduced, and the efficiency of coupling to an optical fiber is enhanced. Thereby, a structure of coupling to the optical fiber can be simplified.

Abstract: PURPOSE:To set power for the driving a printing head to a definite value or less, by setting the number of printing lines so as to set the count value of picture element information to a definite value or less and allowing a printing head to simultaneously print paper over the set numbers of printing lines. CONSTITUTION:CPU21 controls a paper feed motor 9 and feeds paper to a leading line to which printing is applied by a printing head 10. The number of picture element informations in a row direction within the next (N=)5 lines among the printing information stored in RAM26 is counted in the line direction and summed up. This sum value is compared with a preset definite value and, if said value is equal to or less than said preset value, CPU21 sets the number (n) of printing lines, which are simultaneously printed by the printing head, to 5 lines and the printing head 10 prints 5 lines. However, if said sum value exceeds the definite value, CPU21 sets the number of printing lines to be simultaneously printed in a reduced number so as to set said sum value to the definite value or less and the printing head 10 simultaneously prints the set number of lines. Therefore, the driving power of the printing head does not exceed the definite value.
