Title: Optical pickup device
Inventor: MAEDA TAKANORI
IPC: G11B7/135
Filed: 1995-03-15
Abstract: PURPOSE: To read out optical information of high utilization efficiency from both of different optical recording media by correcting the spherical aberration considered to be necessary for reading out the information from the optical recording media having the different thickness of the substrate by a ray flux splitter. CONSTITUTION: A collimator lens 23 collimates the ray flux corresponding to P polarized light to parallel rays and imparts the refraction different from the refraction of the P polarized light to the ray flux corresponding to S polarized light of the optical path length shorter than the optical path length of the ray flux corresponding to the P polarized light. The ray fluxes passing the lens 23 are, therefore, made incident on an objective lens 24 with the different incident faces of the peripheral edge rays while the optical axes are the same as each other. The spherical aberration is so corrected as to be made nearly zero to the respective incident ray fluxes in the lens 24. Then, the lens 24 focuses the respective ray fluxes in the state that the spherical aberrations are corrected. Then, the reading out of the information of the optical disk is possible if the information recording surface exists within the range where the spherical aberrations are corrected. As the result, the information from the optical recording media having the different thicknesses of the substrates is read out by correcting the spherical aberrations.

IPC: F02B27/02
Filed: 1989-03-08
Abstract: PURPOSE:To improve the effect of inertia supercharging by connecting plural numbers of intake ports, where close timing comes nearer, to a common intake passage, and also connecting the other intake ports to an independent intake passage. CONSTITUTION:Intake ports 2-5 are installed in one cylinder 1, while close timing of these intake ports 2, 3 is set so as to deffer from that of the other intake ports 4, 5. The intake ports 2, 3 are connected to a first common intake passage 15 and the other intake ports 4, 5 to a second common intake passage 23, respectively. With this connection, a same phase pressure wave being generated in the common intake passage 15, 23 just before the close timing is led into a combustion chamber from the intake ports 2, 3 and the intake ports 4, 5 connected to these common intake passages 15, 23, spitting due to interference between the intake ports is brought to almost nothing. Therefore the effect of inertia supercharging can be improved.

Title: Signal phase controller for optical communication
IPC: G02F2/02
Filed: 1992-03-13
Abstract: PURPOSE:To easily perform phase control over the optical communication without using any optical memory by providing a specific optical cable and a light output terminal for transmitting a light signal having wavelength outputted by a wavelength converting means. CONSTITUTION:The light signal lambda1 inputted from the light input terminal 1 passes through the optical cable 2 and has its wavelength converted from lambda1 to lambda2 by a wavelength converting element 3. The wavelength lambda2 obtained by the wavelength converting element 3 is set depending upon the value of a current I that a wavelength setting means 4 sends to the wavelength converting element 3. The output light of the wavelength lambda2 from the wavelength converting element 3 is transmitted by an optical fiber 6 and a reception-side wavelength converting element 11 converts the light to wavelength lambda3 equal to the wavelength lambda1 at the time of the input. The output light of the wavelength lambda3 from the wavelength converting element 11 is transmitted by an optical cable 14 and outputted from a light output terminal 15. Thus, the phase of the output signal can be controlled by the simple constitution without using any electric memory.

Title: Protection controller for air conditioning equipment
Inventor: ISHIDA TETSUYA
IPC: F25B49/02
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To secure safety by judging whether the actuation of a protective device which cuts a power source for a compressor is caused by either a rise in a high pressure or malfunctioning when the high pressure in a refrigerating cycle rises abnormally to stop the operation when it is caused by the rise in the pressure. SOLUTION: When air conditioning equipment is operated, a power source voltage 16 is applied to a coil 10 by a high pressure protective device 14 and the operation of a compressor 15 continues. Under such a condition, when the high pressure rises above a prescribed value or when the protective device 14 malfunctions, the protective device 14 is opened. But at this point, a computer 2 converts the high pressure from temperature data from thermistors 17-19 and the number of revolutions of a fan 20. When a value thus obtained is within a working range of the protective device 14, the protective device 14 is determined to be actuated and the operation of the compressor is stopped. On the other hand, when it is not within the working range, the malfunctioning of the protective device 14 or instantaneous power failure is determined to occur to suspend the operation of the compressor 15.  Then, after a fixed time, the compressor is rerun.

IPC: H04M1/00
Filed: 1987-03-11
Abstract: PURPOSE:To adjust the display density of a display device automatically by converting the moving position or direction of a telephone set into a resistance and discriminating the position or direction depending on the resistance. CONSTITUTION:When a telephone set is installed, a movable contact 1 is moved in the direction of gravity and goes to a standstill and an inherent resistance is shown with a fixed contact 2. In this case, a guide bar 3 guides the movable contact 1 so that the movable contact 1 has a stable and accurate inherent resistance with the fixed contact 2. When a telephone set is moved, the movable contact 1 is moved and a specific resistance is inputted to a delay circuit 5. On the other hand, since power is supplied to an LCD display device through a delay circuit 5 from a power supply circuit 7, the display density of the LCD display device 6 is adjusted automatically by the change in the inherent resistance.
