Patent JP-H0658812-A (JP)
Title: Spectrooptical apparatus
Inventor: SASAKI YOSHIYUKI
IPC: G01J3/36
Filed: 1992-08-07
Abstract: PURPOSE:To obtain a significant data in a short time eliminating useless measurement by mounting a measuring sensor at a fixed angle to an incident direction of light so that no reflected light on the surface of the measuring sensor will return to a diffraction means. CONSTITUTION:A silicon photodiode array 14 as measuring sensor is arranged to have a normal of a photodetecting surface thereof at a fixed angle (e.g. 30 deg.) to the incident direction of light from a grating 12. The reflected light L1 on an object turns to a transmission light L2 passing through an incident slit 10, reaches the grating 12 diffusing and turns to the light L3 to form an image on a silicon photodiode array 14. As the photodetecting surface of the silicon photodiode array is at a fixed angle to the light from the grating 12 the reflected light L4 fails to reach the grating 12. This eliminates the chance to detect a component of a wave length other than the set wavelength with the silicon photodiode array 14 thereby enabling the avoiding of a phenomena otherwise leading to a grave disturbance in function of a spectrooptical apparatus.
Patent JP-S6271333-A (JP)
Title: Phase locked oscillator
Inventor: MUTO HIROSHI
IPC: H03L7/14
Filed: 1985-09-24
Abstract: PURPOSE:To hold an output frequency to a voltage before a fault takes place in a reference input even when a reference input signal is faulty by providing an occupancy rate converting circuit. CONSTITUTION:If an error takes place in a reference input signal fed to a reference input terminal 100, an error detection circuit 7 detects it to invert the level of a selection signal to be logical '0'. As a result, the selection circuit 2 selects and outputs a signal from a occupancy rate converting circuit 6. Further, the circuit 6 stops the occupancy rate converting operation to keep the duty factor just before the selection signal is inverted. As a result, a signal having a constant occupancy rate is fed to the 1st low pass filter circuit 3. A DC voltage being the result of an output signal from the circuit 6 eliminated by an undesired high frequency component is sufficiently identical to the control voltage fed to a voltage controlled oscillation circuit 4 when the reference input signal is normal. That is, the output voltage (i.e., the control voltage of the voltage controlled oscillator circuit 4) of the 1st low pass filter 3 is unchanged even when the reference input signal is in error.

Abstract: PROBLEM TO BE SOLVED: To obtain a picture displaying method making it possible to visually recognize the wide range of the wall surface of a three-dimension texture on one screen by making a picture just like looking at the direction of the center line of a visual field at a visual angle larger than a specific value. SOLUTION: When an ultra wide angle direct-vision screen is selected as a screen form desired to display, an ultra wide angle direct-vision screen preparing and displaying part is started. The ultra wide angle direct-vision screen preparing and displaying part prepares and displays a screen just like looking at the direction of the center line of the visual field at a visual angle larger than 180 deg. from a visual point. In order to do that, an invivo tissue image prepared by extracting pixels in the range of an inputted CT value is displayed to input the position of a visual point E1 in the invivo tissue image and to input the direction of the center line of the visual field SC.  Namely, the picture is prepared and displayed just like looking at the direction of the center line of the visual field SC from the visual point E1 at a visual field angle θ of about 200 deg., e.g. is prepared and displayed. Thus, a tumor Y which can not be recognized visually by a conventional endoscope image of a visual field angle smaller than 180 deg. can be recognized visually.

Title: Bubble storing device
Inventor: MORI YUTAKA
IPC: G11C19/08
Filed: 1981-12-30
Abstract: PURPOSE:To discriminate easily the operating condition of a bubble storing device equipped with a major loop and a minor loop, by reading, when information is read out from other minor loops, together with the information on the same address having the marker loop. CONSTITUTION:The output of a device which designates a bubble storing device 10 as a whole is serially inputted into a sense amplifier 11 and amplified. At the same time, a marker loop is also read out. When the marker loop is read out, a strobe pulse synchronized with the marker loop output is obtained from a controlling circuit to operate with the marker loop output at an AND operating circuit 13 and to set a flip-flop 14 by the output of the circuit 13. Since the output from the marker loop is usually ''0'', even when an output ''1'' is obtained from a controlling circuit 12, the flip-flop 14 cannot be set. If an address is bubble written in the major loop, the flip-flop 14 is set to alarm defects which causes defective operations of the storing device.

Title: Oscillation circuit
Inventor: TANOI SATOSHI
IPC: H03B5/36
Filed: 1989-08-16
Abstract: PURPOSE:To attain the oscillation at a high frequency by providing a transfer gate between an output side of a vibrator and a PMOS and an NMOS gate of an inverse amplifier circuit and providing a level fixing means fixing a level of both the MOS gates to a prescribed level. CONSTITUTION:When an enable signal E of logic '1' is inputted to an input terminal 50, an NMOS 51a is turned on. Moreover, since the output of an inverter 52 goes to logical '0', a PMOS 51b is turned on to turn off an NMOS 53. As a result, an input of an inverting amplifier circuit 55 and an external connection terminal 54 are connected via a transfer gate 51, then the circuit is in the oscillating state. In this case, an output terminal 56 and an external connection terminal 57 are driven by the inverting amplifier circuit 55. Since one stage of a transistor(TR) circuit only is provided between an output node Q of the circuit 55 and a power supply Vcc and between the output node Q and a ground level Vss, the voltage drop by two stages of TRs is avoided and a high frequency oscillation is attained.
