Title: Trigger pulse generator
Inventor: YOSHIDA HIROYUKI
IPC: G01R13/32
Filed: 1981-11-30
Abstract: PURPOSE:To achieve a waveform indication by applying a first signal output during the positive period within one cycle of a square wave signal of a specified duty ratio and the second signal output during the subsequent remaining period as one input signal with respect to a trigger pulse generator of a waveform display. CONSTITUTION:A switching pulse input as waveform (a) is inverted into (b) with an inverter. Q outputs of a D flip flop of a counter respectively present waveforms (c), (d) and (e), (f). An AND gate 5 computes (bXdXe) and provides an output (g) while an AND gate 6 provides an output (h) of (bXcXf). Output signal waveforms of the first channel made by reproduction of a sweep tape are displayed on an oscilloscope starting from the generation of the output pulses of the AND gate 6 while output signal waveforms of the second channel are displayed on the same time base in substance overlapping the output waveforms of the first channel from the generation of output pulses of the AND gate 5. This enables the observation of any delicate difference between both the waveforms from the waveform display.

Filed: 1984-09-12
Abstract: PURPOSE:To enable effective display of output level with a simple structure, by adding an output of a power amplifier to a light emitting diode given a DC voltage to such an extent as emitting no light when receiving no signal. CONSTITUTION:An output of a power amplifier 1 for audio signals is inputted into a speaker 2 and a cathode of a light emitting diode LED3 is grounded to apply a DC voltage of 1.5-1.6V to an anode with resistances 4 and 5.

Title: Optical displacement measurement system
Inventor: NAKAUCHI SHUNSAKU
IPC: G01D5/26
Filed: 1985-08-30
Abstract: PURPOSE:To calculate the absolute value of the displacement of an object to be measured on the basis of a specific interval and the interval between images of reference lines provided to the object to be measured at the specific interval by photodetecting the images by an image sensor. CONSTITUTION:A target plate 1 is fixed on the object 4 to be measured and lighted by light sources 3 from behind slits which are formed previously at the specific interval to form their images on the liner image sensor 7. The positions of images 8 and 9 of the slits 2 in the initial state move to the positions of images 81 and 91 in response to an external force. The image sensor sends out of charges of respective photodetecting elements with a clock and the number of clock pulses between the reference lines is counted. The reference constant between the reference lines is divided by the counted value to find the absolute length that one photodetecting element has and the absolute length is multiplied by the movement extent of the reference lines to calculate the absolute value of the displacement. Consequently, the absolute value of the quantity of displacement of the object to be measured is found without reference to the focal length of a lens 5 and the distance between the lens and object, so this system is convenient.

Title: Locking mechanism for head carriage
Inventor: INANOBE TOSHIHARU
IPC: G11B21/02
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To guarantee the locking force of a head carriage by directly pressing two bearings placed side by side in a tracking direction to a rail for carriage guiding by a locking piece so as to lock the head carriage. SOLUTION: When electric conducting to a solenoid 2 is stopped, since a plunger 2a is returned in an arrow direction a2 , a driving force transmitting piece 3 is rotated in an arrow direction b2 by the elastic force of a spring 9 and, by the rotation of this driving force transmitting piece 3, a locking piece 23 presses and locks bearings 25a and 26a. Thus, each of the bearings 25a and 26a is pressure-contacted with a guide rail 14 by the locking piece 23. Thus, while an optical head carriage 21 is locked, a pressing force produced by the locking piece is directly transmitted to the bearings 25a and 26a.

Title: Acceleration sensor
Inventor: HASE YUJI
IPC: H01L29/84
Filed: 1990-07-19
Abstract: PURPOSE:To provide an acceleration sensor capable of high-temperature operation by using the same metal (gold) both for interconnections used to connect electrode pads with diffused resistors on an insulating layer of a single-crystal silicon substrate and for wires used to connect the pads with lead posts. CONSTITUTION:An acceleration sensor includes a single-crystal silicon substrate 1, which has a fixed end attached to a support member 31 and a free end provided with a weight for increasing sensitivity. When a force acts on the sensor because of the acceleration or deceleration of a vehicle, the silicon substrate 1 bends at a thin part la. This deformation causes a change of the signal output from a bridge circuit of diffused resistors 15a-15d, and the change is used to detect acceleration. This sensor is capable of high-temperature operation since the same metal (gold) is used for interconnections, pads, and leads.
