Title: Method for detecting drop in number of rotation
Inventor: HIRATSUKA YOSHIAKI
IPC: G01R31/00
Filed: 1990-09-06
Abstract: PURPOSE:To detect a drop in the number of rotations by means of circuits built into a fan by comparing a voltage signal which is obtained by integrating a rotation signal of pulse width corresponding to the number of rotations of the fan with a threshold. CONSTITUTION:A voltage signal which is obtained by integrating a rotation signal from a collector of a transistor Tr 51 by an integrating circuit 21 is compared 30 in a threshold test circuit 22 with threshold voltage which is set by resistors 31, 32, and an alarm signal corresponding to the result is output. That is, when a fan is normally rotating, a signal with constant pulse width is output to the collector of the Tr 51, and the circuit 21 outputs a voltage signal higher than the threshold voltage, so that the circuit 22 outputs an alarm signal of a low level, while if the number of rotations of the fan drops to approximately 30% or lower of the reference number of rotations, the voltage signal level is a threshold or lower, so that the alarm signal is at a high level. Thus a drop in the number of rotations can be detected by the circuits 21, 22 built into the fan, thereby detecting a failure in air-cooling operation prior to shutdown of a system.

Title: Focussed ion beam device
Inventor: ISHITANI TORU
IPC: H01L21/205
Filed: 1991-09-19
Abstract: PURPOSE:To enable the etching step, etc., in the path of a stable focussed ion beam current to be performed by a method wherein ions are led-out in a constant-current mode by feeding the aligner signals corresponding to the fluctuation in the leading-out voltage to the aligner between a leading-out electrode and an objective lens. CONSTITUTION:Ions are focussed by a focussing lens 130 including a leading-out electrode 101, a lens electrode 102 passing through an electrostatic aligner 103 for making the ions pass through the center of an objective lens 106. The leading-out electrode 101 is actuated in the constant-current mode. At this time, even if the leading-out voltage is fluctuated to shift the ion incoming direction from the focussing lens 130, the correction voltage signals are read-out by the characteristic curve of the fluctuated voltage and an aligner correction voltage so as to impress the aligner 103 with the aligner correction voltage comforming to said signals. Accordingly, the processing step such as the etching step using the focussed beams can be performed stably.

Title: AlGaInP LIGHT EMITTING DIODE
Inventor: UDAGAWA TAKASHI
IPC: H01L33/30
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To prevent the operational current of an AlGaInP light emitting diode from flowing into the region present just below its electrode, by implanting ions into the projective region of its electrode which is present in its III-V compound semiconductor crystal layer. SOLUTION: Into an ion implanting region 111, an ion seed comprising the element other than the one constituting a metallic thin-film 106 is implanted differently. Since the ion implanting region 111 is so provided as to inhibit the flowing of a driving current into the region present just below an electrode 109, the contact of the region 111 with a III-V compound semiconductor crystal layer must be non-ohmic. Therefore, with respect to the layer constituting an n-type III-V compound semiconductor, Zn of group II element or carbon of group IV element becomes a favorable implanting ion seed. By implanting one kind of these impurity ions into the layer constituting an n-type III-V compound semiconductor, a pn-junction portion is formed in the ion planting region 111.  By forming the ion implanting region 111 including the pn-junction therein, the driving current of an AlGaInP light emitting element is prevented surely from flowing into the region present just below the electrode 109.

IPC: G01R13/32
Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To block the correlation between a captured clock and a waveform to be sampled by imparting an offset to the input of a phase locked loop thereby varying the phase of captured clock in between the captured cycles. SOLUTION: A phase detector 504 compares the phase between a reference clock 502 and a captured clock 518 subjected to scaling. An offset 516 is applied to the output of phase detector 504 by an adder 506. Output from a D/A converter obtained by inputting a random number, for example, is employed for offset. The sum of the output 520 from the phase detector 504 and the offset 516 is fed to a loop filter 508 which then produces an output 522 for controlling a voltage controlled oscillator 510 to produce a captured clock 514. A frequency divider 512 connected with the captured clock 514 produces a captured clock 518 subjected to scaling which is delivered to the phase detector 504.

Title: Optical encoder
Inventor: YOSHIDA KATSUMASA
IPC: G01D5/36
Filed: 1989-09-19
Abstract: PURPOSE:To take a highly accurate measurement by engaging a couple of comb-shaped photodetectors with each other and determining the shapes of the photodetectors so that the phase difference between the outputs of those photodetectors is 180 deg.. CONSTITUTION:As a rotary disk 2 rotates, the part of a light receiving part 4 which is irradiated with an array of pieces of luminous flux passed through slits 7 moves. At such a time, the pitch (p) of the array of pieces of luminous flux is equal to the pitch of the basic photodetectors, so photodetection signals generated by all the basic photodetectors in the same comb-shaped photodetectors are in phase. Further, when the width of the basic photodetectors is nearly equalized to P/2, the width of the part on the part 4 which is irradiated with the parallel pieces of luminous flux and the width of the part which is not irradiated are both P/2. Consequently, the light receiving signals 3a and -3a, and 3b and 3b outputted by the comb-shaped photodetectors of the same couple of comb-shaped photodetectors of the same couple of comb-shaped photodetectors are 180 deg. out of phase. Therefore, the signals 3a and -3a, and 3b and -3b are amplified differentially to obtain a 1st and a 2nd encoder signal having a high SN ratio.
