Title: Optical wavelength multiplex recording and reproducing device
Inventor: UMETSU NOBUHIKO
IPC: G11B7/005
Filed: 1993-11-08
Abstract: PURPOSE:To reduce the size and weight of this device and to reduce the cost with simple constitution by causing the transmission or reflection of irradiation light and return light to and from a recording medium by a wavelength selection element in recording and reproducing. CONSTITUTION:Optical wavelength multiplex recording by a two-photon recording method is conducted by irradiating the optical wavelength multiplex recording medium 4 with the recording light of the selected wavelength from a light source section by condensing this light thereto via the wavelength selection element 2. At this time, the return from the recording medium 4 is rotated 90 deg. in the plane of polarization and transmits the wavelength selection element 2. This return beam is partly reflected by a beam splitter 23 and is made incident on a detecting section 28, by which a servo signal is obtd. At the time of reproducing, the laser beam from the light source 1 is reflected by the wavelength selection element 2 and the fluorescence generated beam from the recording medium 4 is rotated 90 deg. in the plane laser beam is transmitted through the wavelength selection element 2 and is introduced via a filter 26 and a condenser lens 27 to a photodetecting section 3, by which the recorded information at the respective wavelengths is detected. At this time, the selecting element 2 reflects the reproducing light without allowing the transmission and allows the transmission of only the excited fluorescence. As a result, the recording and reproducing are conducted with the simple constitution.

Title: Load operation control device
Inventor: TOMITA KENJI
IPC: B60R16/023
Filed: 1997-10-14
Abstract: PROBLEM TO BE SOLVED: To reduce the phase shift of a twinkling by that a first control means sends the synchronizing signal of a prescribed cycle as a standard cycle for a second control means and the second control means synchronizes again the action of an own certain cycle by the standard cycle and acts a load connected to itself. SOLUTION: ECU 12 sends a twinkle synchronized signal for ECU 11. When the ECU 12 judges the start of the twinkle action of a winker, a winker stop signal sent through a multiplex communication circuit 14 for the ECU 11 is switched to a winker action order and at the same time as switching, the sending of the twinkle synchronized signal of the prescribed cycle which is the standard cycle is started. At every time when the ECU 11 receives the twinkle synchronized signal from the ECU 12, a canter for counting the twinkle cycle is reset and a re-synchronization is applied to the twinkling of a winker lamp. Thereby, the shift of the twinkle phase of the winker lamp can be reduced to the extent to which the disorder of the exterior twinkle phase can not be seen.

IPC: C23C18/12
Filed: 1993-10-14
Abstract: PURPOSE:To form a uniform oxide ceramics film free from cracking on the surface of a body to be treated with a high productivity by electrostatically atomizing a soln. of a metallic compd., uniformly depositing the resultant fine particles on the surface of the body to be treated while volatilizing the solvent and carrying out burning. CONSTITUTION:An alcoholic or aq. soln. or a sol of a metallic compd. such as alkoxide or a silicon compd. is electrostatically atomized and the resultant fine particles are deposited on the surface of a body to be treated to form a film uniform in thickness. At that time, the atomized fine particles transferred in the space between the atomizing part and the surface of the body to be treated are irradiated with IR or microwaves to volatilize the alcohol or water. A gel film hardly contg. solvent molecules can be formed in a desired thickness in a one-pass process. This film is then converted into the objective ceramics film by burning, e.g. at about 300-1,200 deg.C in an atmosphere selected according to the purpose.
