Title: Dubbing device of optical disk reproducing tape
Inventor: SOEDA SHUICHI
IPC: G11B19/02
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To prevent the level fluctuation of a signal from a MIX circuit by making the connection of the MIX circuit to be for a tape recording signal only in such a manner that an optical disk reproducing signal is mixed with a tape recording signal or reproducing signal and the tape recording signal only is changed over and outputted for monitoring. SOLUTION: The signals of R and L channels are selected for MIX or separation by an output changeover switch of an operation part 16 and outputted through an output changeover circuit 7. When the recording signal is selected to the CD reproducing signal by an input changeover switch of the operation part 16, the output of the CD reproducing signal to a MIX output terminal 9 is interrupted by the output changeover circuit 7. When the input changeover switch of the operation part 16 is selected to the LINE IN side and the output changeover switch is slid to the MIX side, the CD reproducing output is mixed to the tape recording or reproducing signal by the output changeover circuit 7 and outputted from the MIX outputting terminal 9.  When the CD is reproduced for dubbing the tape, the output for monitoring is made by interrupting the connection of the MIX side of the CD reproducing output.

Title: Cleaning method for carbon monoxide sensor
Inventor: KONO TAKASHI
IPC: G01N27/406
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To prevent the aging of a solid electrolytic carbon monoxide sensor, i.e., the increase of H2 /CO ratio, deterioration of response and fluctuation of air base, by applying a voltage between the electrodes of solid electrolytic carbon monoxide sensor for a predetermined time and then performing heat-up processing. SOLUTION: The voltage being applied between the electrodes of a sensor must have same polarity as the electromotive force being generated between the electrodes of sensor. The applying voltage is 1-5V and when it is required to shorten the applying time, a voltage of 4-5V is applied thus obtaining sufficient effect through processing of 4-15sec. An applying voltage higher than 5V may cause damage on stabilization zirconia. A sensor deuterated through long term use is applied with voltages of 1, 3, 5V for 10sec (polarization) in order to lower the sensitivity of carbon monoxide thus enhancing the S/N ratio relatively. This effect is especially eminent when polarization is carried out with applying voltage of 5V.

Title: Sample capsule for x-rays microscope
Inventor: MIZUNOE KATSUZO
IPC: G21K7/00
Filed: 1991-09-27
Abstract: PURPOSE:To enable a sample capsule to be assembled so that the thickness of a sample chamber formed between two membranes is constantly equal to a specified value. CONSTITUTION:A sample capsule for X-rays microscope consists of a pair of membranes 1 and a spacer 9 which is sandwiched between them. The thickness of the sample chamber 10 is determined by that of the spacer 9. Namely, it is as thin as 3 to 10mum. Therefore, even if a clearance is formed due to blockage between the spacer 9 and the membrane 1 or between the spacers by a foreign object, confirmation thereof is difficult. By constituting the spacer 9 of a conductive material and by allowing current to flow and performing monitoring electrical disconnection when a foreign object blocks an area between the spacer 9 and the membrane 1 or between the spacers, tight contact between the spacer 9 and the membrane 1 or between the spacers 9 can be detected. The thickness of the sample chamber reaches a specified value due to the tight contact.

Title: Refrigerant composition and binary refrigerator using the same

Filed: 1998-09-03
Abstract: PROBLEM TO BE SOLVED: To obtain a compsn. which has a sufficient refrigerant capability by mixing an azeotropic mixture of chlorodifluoromethane and octafluoropropane with n-pentane in a specified amt. based on the amt. of the azeotropic mixture. SOLUTION: This compsn. is prepd. by mixing an azeotropic mixture having an azeotropic point of -47 deg.C and comprising chlorodifluoromethane having a b.p. of -40 deg.C and octafluoropropane having a b.p. of -36.7 deg.C with n-pentane in an amt. of 14 wt.% or lower of the amt. of the azeotropic mixture. Though n-pentane has a high b.p. (36.0 deg.C), it is well compatible with a compressor oil; therefore, a specified amt. of n-pentane mixed enables the oil in the state of being dissolved in n-pentane to be returned to a compressor, thus enabling troubles such as locking of a compressor due to oil-up to be prevented. When a specified amt. of dichloromonofluoromethane is added to the azeotropic mixture, effects similar to one obtd. by n-pentane can be obtd. without the necessity for installing an oil separator for separating the oil.

Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To obtain a process for producing a liquid crystal display element having an excellent contrast. SOLUTION: This process for production consists in injecting antiferroelectric liquid crystals or ferridielectric liquid crystals in an isotropic phase into a liquid crystal cell consisting of a pair of glass substrates attached with transparent electrodes, insulating films and oriented films subjected to rubbing treatments and slowly cooling the liquid crystals to cause the phase transition to a smectic A phase and, further, slowing cooling the liquid crystals to cause the phase transition to the antiferroelectric phase or the ferridielectric phase.  In such a case, the operation to heat up the liquid crystals again to the isotropic phase after the phase transition to the smectic A phase, then the operation to slowly cool the liquid crystals to cause the phase transition to the smectic A phase is executed at least once, by which the orientation defects of the liquid crystal phase are decreased. As a result, the domains varying in the orientation directions and dia type defects are drastically decreased or annihilated, by which the liquid crystal display element having the improved contrast is embodied.
