Title: Magnetic recording and reproducing device
Inventor: OTANI MINORU
IPC: G11B5/027
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To enable performing error protection in a high speed reproducing mode by an error protection function in an ordinal reproduction mode without developing a new LSI. SOLUTION: In a double speed reproduction mode, a reproduced data rearranging circuit 11 distributes each reproduced data 9a, 9b read by two magnetic heads 8a, 8b to signal processing groups 2a, 2b for each sequence number, also, each reproduced data 9a, 9b are rearranged so that each track number belonging to the same sequence number is continued in the same signal processing group. Thereby, in the signal processing group 2a, error protection in the double speed reproduction mode can be performed by the same error protection function as that of a normal reproduction mode.

CONSTITUTION:The fine metal and/or metallic compd. grains are dispersed in water by using an org. polymer having protective colloid activity, if necessary, The dispersion is mixed with a nonaqueous liq. which is phase-separated from water in 0.01-50, preferably <=1, times the volume in the presence of a surfactant, agitated and brought into contact with each other. The amt. of the surfactant is controlled to 0.01-5wt.% of the water. Further, the contact is made in the presence of 0.005-30%, based on water, of a water-soluble inorg. acid salt and/or a water-soluble org. acid salt without surface activity, or the salt is added after contact. The grain is transferred to the nonaqueous liq. from the dispersion to obtain a two-phase mixture. The nonaqueous liq. in which the grains are dispersed is isolated from the aq. phase of the two-phase mixture almost free from the grains.

Title: In-tunnel monitoring system
Inventor: MORI AKIHISA
IPC: G01N29/14
Filed: 1999-12-22

Patent JP-2000186866-A (JP)
Title: Absorption refrigeration apparatus
Inventor: HAYASHI YASUHEI
IPC: F25B15/00
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To keep stable capability by eliminating refrigerant vapor leakage into a regenerator and an overflow of an absorption solution into a refrigerant recovery tank. SOLUTION: An intermediate concentration absorption solution separation cylinder 12 is enclosed with an absorption solution limit plate 15 equipped with a valve mechanism 16. When a liquid level of an absorption solution in the intermediate concentration absorption solution separation cylinder 12 is low, refrigerant vapor separated from an absorber passes through the valve mechanism 16 and is moved to a refrigerant recovery tank 10. When the liquid level of the absorption solution is high, a float valve structure 17 closes a valve hole and hence the absorption solution is prevented from being overflowed to the refrigerant recovery tank 10.  The refrigerant vapor produced here moves from a small opening 18 to the refrigerant recovery tank 10, but since an opening area is small, the amount of the movement is restricted and hence pressure in the intermediate concentration absorption solution separation cylinder 12 becomes higher, whereby supply of a solution to the regenerator from the absorption solution pump is reduced and the amount of discharge from the regenerator is increased. Further, variations of the liquid level of the absorption solution are limited, and hence stable capability is kept.

Title: Multioxygen-containing compound, photoresist composition, photoresist pattern formation, and semiconductor device
Inventor: LEE GEUN SU
IPC: G03F7/038
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To efficiently prevent the diffusion of an acid produced in exposure process by incorporating a photoresist composition with a crown ether or polyethylene glycol derivative as a multioxygen-contg. compoud. SOLUTION: The diffusion of an acid produced in exposure process is effectively prevented by incorporating a photoresist composition with a multioxygen- contg. compound, i.e., a crown ether of formula I (n is 1-5) or formula II ((a) to (c) are each 1-5) (e.g. 12-crown-4,[2.2.2]bicyclic crown ether) or a polyethylene glycol derivative of formula III [R1 and R2 are each a (substituted) 1-10C alkyl containing H and/or OH, or the like; m is 1-20] (e.g. polyethylene glycol, polyethylene glycol dimethyl ether). Being low in the absorbance for rays corresponding to an ultra-short wavelength region of <=250 nm, the above crown ether or polyethylene glycol derivative never deteriorates the photosensitivity of a photoresist composition even if incorporated therein.

Title: Ion current detecting device of internal combustion engine
Inventor: NISHIGAKI TAKAHIRO
IPC: B60K6/445
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To prevent wrong determination of a misfire or the like according to the ion current detection result by limiting the combustion state determination of an internal combustion engine based on an ion current according to the current flowing through a motor and a motor control device of a hybrid vehicle. SOLUTION: An electric control unit(ECU) 40 reads a voltage value of an ignition plug 16 part generated by an ion current, and compares the read value with a designated value to conduct the required control operation when a misfire is determined. In the ion current detecting device of a hybrid vehicle, when a large current flows through a motor, noise is generated to have a bad influence to the ion current to cause wrong determination of a misfire. When a misfire determination limiting routine is executed, the noise present is determined when the detection values Im of currents of motors MG1, MG2 are larger than a designated amount, when the change rate (dIm/dt) of the detected current value is larger than a designated value, or when a regenerative control current Irm flows.  Thus, it is possibe to prevent wrong determination of the engine combustion state according to the detection of an ion current influenced by noise.
