Title: Vibration isolating device for camera
Inventor: SUMIO HIROSHI
IPC: G01H17/00
Filed: 1986-09-29
Abstract: PURPOSE:To determine the initial value of a speed at the time of acceleration- speed conversion by using a deviation detector which utilizes an optical sensor in combination with a camera-shake detector consisting of only an acceleration sensor and an integrating device. CONSTITUTION:Signals from sensor devices 140a and 140b are sampled as a 1st and 2nd frame at a certain interval of time and the relative speed of a body in a image is calculated from the phase difference and the time interval between these signals. Simultaneously, a one-shot reset pulse is sent to an integrator 45b through a terminal P3 in the middle of the time from the signal sampling of the 1st frame to the sampling of the 2nd frame. The integrator 45b beings to integrate acceleration at this point of time and its output signal indicates the relative speed between a subject and a camera on an image plane at this point of time as the relative speed between the subject and camera based on a reference speed which is taken as 0. A processor 120 calculates a camera shake by phase detection after the sampling of the image of the 2nd frame. Consequently, the possibility that a deviation quantity is inaccurate or that an integral value is saturated is eliminated.

Title: Optical pickup device
Inventor: NAKAYAMA MASAHIKO
IPC: G11B11/10
Filed: 1994-09-27
Abstract: PURPOSE: To make it possible to exactly generate a phase difference of 90 deg. by providing this optical pickup device with a phase difference imparting means consisting of a set of plural total reflection prisms between P polarized light and S polarized light. CONSTITUTION: A polarization beam splitter 3 has a function to reflect the S polarized light and to allow the transmission of the P polarized light. The first total reflection prism 4 and the second total reflection prism 5 generate a phase difference of about 90 deg. between the P polarized light and the S polarized light. An objective lens 6 forms the microspot of the luminous flux from the second total reflection prism 5 on an optical disk. A condenser lens 7 condenses the light reflected from the optical disk and a cylindrical lens 8 generates an astigmatism. Quadrisected photodetector 9 detects focus error signal, etc., from the light past the cylindrical lens 8.  As a result, the phase difference generated by the total reflection prism not provided with dielectric film on the reflection surface is determined only by the refractive index of the total reflection prism and, therefore, the phase difference of 90 deg. is generated between the P polarized light and the S polarized light without receiving the influence of the variation, etc., in the film thickness.

Abstract: PURPOSE:To supply stably a charging current independently of the duty ratio by driving two sets of holding circuits where no supply current is produced when a node is at a low potential by transistors (TRs) of a prescribed connection respectively by a refresh pulse and an inverted refresh pulse. CONSTITUTION:When a node 2 of a holding circuit 12 is brought into a low potential via a driver circuit 11, a TR9 is not turned on via a node 8 even if the refresh pulse phi is inverted to a high level and a useless supply current is interrupted.

The circuit 17 the same as the circuit 12 supplies the recharging current similarly when the inverted pulse phi' is impressed. Thus, the recharging current is supplied stably at all times independently of the duty ratio of the refresh pulse.

Abstract: PURPOSE: To decrease NOx in an exhaust gas and to solve thereby a problem of unreacted ammonia by mixing NH3 in the exhaust gas contg. NOx and irradiating this mixed gas with an ultraviolet ray with a specified wavelength. CONSTITUTION: Test gases such as NO, N2 , CO2 , O2 and NH3 controlled into an arbitrary flow rate by means of a gas flow rate controller 4 are mixed uniformly by means of a gas mixer 5 and are introduced into a reactor 2 with irradiation windows 3 made of a synthetic quartz on its both ends. H2 O in the test gases is fed by means of a humidifier 6. The test gases coming out of the reactor 2 pass through a filter for collecting reaction products and are guided into an NH3 analyzer 9 equipped with a recorder 10 and are then exhausted into the atmosphere. The gas mixer 5 and the reactor 2 are stored in a thermostat bath which kept at 350 deg.C by imaging the outlet of a denitrification apparatus. As the light source of ultraviolet rays, an excimer laser 1 is used and the ultraviolet rays with wavelength of 170-230nm are used for irradiation.  As the result, NH3 is decomposed into (NH2 +H), which is reacted with NOx to decrease NOx.
