Title: Laser oscillation frequency stabilizing device
Inventor: SAKAI YOSHIHISA
IPC: H01S5/068
Filed: 1991-06-28
Abstract: PURPOSE:To realize a laser oscillation frequency stabilizing device capable of ensuring higher frequency stability. CONSTITUTION:Emitted light from a semiconductor laser 1 is halved by an optical coupler 2, with one branch light directed to enter an acoustical optical modulator 3 and the other branch light derived as output light. The incident light to the acoustical optical modulator 3 is frequency-modulated with a modulation signal from a high frequency oscillator 9. First and zeroth modulated light beams yielded thereupon are directed to an optical switch 13, and are switched and outputted conformably with an output signal from a high frequency oscillator 14. An output light is directed to enter an absorption cell 7 and absorbed at a specific frequency. A transmitted light through the absorption cell 7 is detected by an optical detector 8. An electric signal from the optical detector 8 is detected in synchronism with a high frequency signal from the high frequency oscillator 14, and an error signal ES produced responsibly to a difference between the mean frequency of the zeroth and first modulated a peak frequency of the absorption cell 7 is rendered to negative feedback to the semiconductor laser 1 to stabilize the oscialltion frequency of the semiconductor laser 1.

Abstract: PURPOSE:To obtain satisfactory bistability and to secure satisfactory storage characteristic by orienting liquid crystal molecules uniformly over the whole surface of a panel by arranging to reduce the difference between the surface polarity of an upper and a lower orientation film formed on a pair of transparent substrate to a small value. CONSTITUTION:Film thickness of an orientation film 21 on a rear glass transparent substrate 11 having a transparent electrode 12 comprising ITO, etc. formed thereon is made thicker than the film of an orientation film 15 faced oppositely thereto interposing ferroelectric liquid crystals 14, and only the surface of the orientation film 15 is subjected to orientation treatment. Thus, the intensity of each surface polarity of the film 21, 15 faced oppositely to each other interposing liquid crystals 14 is balanced by adjusting the film thickness of the film 21 to the thickness so as not to result any difference of surface polarity between the film 21 and the film 15. By this constitution, liquid crystal molecules are oriented uniformly over the whole surface of the panel, and satisfactory bistability is obtained.

Title: Boron nitride coated hard material and its production
Inventor: OMORI NAOYA
IPC: B23P15/28
Filed: 1992-06-18
Abstract: PURPOSE:To produce a boron nitride coated hard material. CONSTITUTION:When a boron nitride coating layer is formed on the surface of a WC-based cemented carbide as a base material to obtain a boron nitride coated hard material, the percentage of a bonding phase in the surface part of the base material is made lower than that in the interior of the base material or the bonding phase is not allowed to exist in the surface part. A surface- modified layer is preferably formed in the surface part of the base material by sintering or heat treatment and the surface of the base material is sintered or heat-treated and then coated with baron nitride. Since the resulting boron nitride coated hard material has very high wear resistance and excellent adhesive strength, it can effectively be utilized for various tools, parts, grinding wheels, etc.

Title: Detecting equipment of oil film floating on water surface
Inventor: IIZAKA TOYOJI
IPC: G01N27/02
Filed: 1995-06-27
Abstract: PURPOSE: To detect an oil film reliably at low costs of equipment and maintenance by immersing an oil film detecting terminal and floats as opposed terminals in a surface part of water and by detecting an impedance between them. CONSTITUTION: A pair of floats 2 functioning as opposed terminals are immersed in water W so that the water W flows between them and about a lower half of an oil film detecting terminal 5 is submerged by changing the amount of penetration of a protecting tube 43 into a support tube 61. When an AC power from an AC power source X is impressed on the terminal 5 and the floats 2 through a converter 42 in this state, an alternating current corresponding to an impedance value of the water W runs between them. When oil floats on the surface of the water W at this time, the impedance value between the terminal 5 and the floats 2 becomes the total value of the impedance values of the water W and an oil film, becoming larger than that of the water W alone, and an indication value of an output device 8 becomes large. Accordingly, the presence of the oil film can be detected.  At the time when the impedance value is larger than a set threshold value, an alarm signal is outputted 8.

Abstract: PURPOSE:To surely understand a message, by changing the speed of utterance of same messages repeatedly in response to the instruction of repetition by the operator. CONSTITUTION:At the 1st utterance of a message, a control section 11 transmits a reset pulse signal to a reset signal line 14 and resets a counter 4, and a gate pulse signal is outputted to a gate signal line 15 to input the output of the counter 4 to an audio output section 10.
