Abstract: PURPOSE:To produce a condensed pyridine-based mevalonolactone intermediate exhibiting a reductase inhibitory effect and useful as an intermediate for synthesizing a medicine for improving hypercholesterolemia by reacting a specified condensed pyridine derivative with a base and subsequently condensing the resultant anion with a specified aldehyde compound. CONSTITUTION:A condensed pyridine derivative represented by formula I [X ring is a (substituted)phenyl or a 5- to 6-membered heteroaryl; R<1> and R<2> are each H, a 1 to 8C alkyl, a 3 to 7C cycloalkyl, a 1 to 3C alkoxy, etc.; R<3> is H, a 1 to 8C alkyl, a 2 to 6C alkenyl, etc.; Y is formula P<+>R<11>R<12>R<13>Hal<-> (R<11> to R<13> are each methyl, ethyl, phenyl, etc.; Hal is a halogen), etc.] is reacted with a base to produce its anion. The resultant anion is then condensed with an aldehyde compound expressed by formula II (R<9a> and R<9b> are each methoxymethyl, trimethysilyl, etc.; R<10> is methyl, ethyl, benzyl, etc.) or formula III, thus producing the objective condensed pyridine-based mevalonolactone intermediate represented by formula IV (Z is a group of formula V or VI) and useful as an intermediate for producing a medicine for improving hypercholesterolemia.

Title: Coordinate input device, drawing system, and storage medium stored with its drawing program
Inventor: KUWABARA KAZUHIKO
IPC: G06F3/0488
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To obtain an input device which can generate a drawing without causing any incompatibility by outputting a detected angle of rotation to a display device as display angle information on drawing data to be drawn by the display device according to coordinate data and rotating the drawing data at an angle corresponding to the sent angle of rotation. SOLUTION: When a drawing is made on the coordinate input device 20 with a coordinate input means 1, its coordinate data are outputted by an output control means 13. The coordinate input means 1 is constituted freely rotatably by a turntable, so the coordinate input means 1 is used and rotated to an easy- to-draw direction. A rotational angle detecting means detects the angle of rotation of the coordinate input means 1 and an output control means 13 outputs the detected angle of rotation to the display device 30. The angle of rotation becomes display angle information on the drawing data to be drawn on the basis of the drawing data, so the display device 30 rotates the drawing data at the display angle and displays them, so that the angle of rotation of the coordinate input means 1 matches the angle of rotation of the coordinate data on the display device 30.

Title: Rhythm detector
Inventor: MORITA MASAHARU
IPC: G10L25/51
Filed: 1984-06-11
Abstract: PURPOSE:To detect rhythm components of a sound signal by supplying the sound signal to a comparator through two integrating circuits having different time constants after rectifying the sound signal. CONSTITUTION:The sound signal from an input terminal 31 is rectified by a rectifying means 11 to become a rectified output waveform (b). This rectified output is led to integrating means consisting of resistances 21 and 22 and capacitors 27 and 26 respectively to become rectified voltage waveforms 35 and 36, and they are inputted to the non-inverted input terminal and the inverted input terminal of a comparator 30. If time constants of integrating means are set properly, the voltage in the non-inverted input terminal of the compartor 30 is higher than that in the inverted input terminal in parts indicated in a figure (c) by oblique lines, and a high-level voltage is outputted to the output, and a waveform (d) of the rhythm detection output is obtained. Thus, rhythm components of the sound signal are detected.

Abstract: PURPOSE:To control air conditioning means, lighting means, visual and acoustic means, vibration means, and aroma generating means so that a sleeping person can get a good sleep by judging the sleeping state on the basis of the output from a piezoelectric element in no contact with and no restraint on the sleeping person. CONSTITUTION:A piezoelectric element 4 in which a polymer piezoelectric material formed into a thin film and having flexible electrode films adhered on both the surfaces is molded into a tape is internally provided, and a belt is fixed to the surface of a mattress 3 in such a manner that it is situated just under the breast part of a human body in bed. When the piezoelectric element 4 is deformed by the body movement of a sleeping person during sleeping, a voltage is generated from the piezoelectric element 4. In sleep judgment means, a timer takes timing operation in the presence of the output from a comparator, and the timing operation by the timer is stopped and reset in the absence of the output. When the time timed by the timer reaches a predetermined time or more, sleeping state is judged by a judging part. Only when the human body is laid on bed and in quiet state, the sleeping state is judged, and room temperature control is performed by control means.

Title: Torque converter
Inventor: KONO SATOSHI
IPC: F16H45/02
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To positively reduce torsional vibration of a power transmission system without causing troubles such as enlargement of the device, an increase in the number of part items, complication of assembling works. SOLUTION: With this torque converter, a recessed part 18 forming a pendulum chamber 21 is formed at the end part wall 16 of a converter cover l. A roller 19 serving as a centrifugal pendulum is rockably accommodated in the recessed part 18. Communicating holes 22 are formed in a cover plate 20 for closing the recessed part 18 to communicate the inside of the recessed part 18 to the inside of a liquid chamber 4 through the communicating holes 22. Since the pendulum chamber 21 is formed in the converter cover 1, the shaft length of the torque converter is shortened. Thus, there is no need to fill the pendulum chamber 21 with lubricating oil, especially, and the need for sealing parts for preventing the leakage of lubricating oil is also eliminated.

Inventor: NOGUCHI MASARU
IPC: F16K41/10
Filed: 1986-05-26
Abstract: PURPOSE:To inhibit the torque of a valve stem from being transmitted to a bellows, by fixing to a valve cap or the bellows a cap fitting ring having a projection to be engaged with a groove formed on an upper outer peripheral surface of a valve member presser ring. CONSTITUTION:A valve member 7 is rotatably connected to a valve stem 6.

Title: Image formation
Inventor: SUGATA MASAO
IPC: G03G15/05
Filed: 1977-10-06
Abstract: PURPOSE:To improve the durability for repeated uses of a screen photosensitive element by applying a liquid containing a non-ionic surface activator, silicone oil of low viscosity and water to the surface of the photosensitive element on each repetition of the image formation. CONSTITUTION:A liqud, which contains in volumetric ration 0.5 to 5 of non-ionic surface activator such as polyoxyethylene alkyl eter, 0.1 to 5 of silicone oil having a low viscosity lower than 100 CP such as dimethyl silicone oil and 90 to 99.8 of water, is applied to the surface of a screen photosensitive element either each repetition of the image formation or intermittently. The liquid thus prepared is applied in need while detecting the contamination and deterioration of the photosensitive element. As a result, since a thin film is formed on the surface of the element, the resistance to the corona ions can be so remarkably improved that the maintenance of the initial characteristics of the photosensitive element can be remarkably improved.

Title: Optical transmission system
Inventor: NOGAMI TAKEKI
IPC: H04B10/11
Filed: 1992-05-13
Abstract: PURPOSE:To make long distance transmission advantageous by devising the system such that a 1st storage section of a transmitter stores a digital signal from an input section and outputs the stored digital signal at a speed slower than the storage speed of the digital signal. CONSTITUTION:A broad band analog signal (b) is sampled by an A/D converter circuit 25 at a frequency higher than that of the signal (b) and converted into a digital signal. A storage circuit 26 stores the signal from the circuit 25 and reads the stored signal at a speed slower than the write speed of the signal to extend the time of the digital signal from the circuit 25 and the result is sent to a coding circuit 27. The circuit 27 codes the signal from the circuit 26 and a modulation circuit 28 modulates the signal to generate a transmission signal. An infrared ray diode 29 converts the transmission signal into an infrared ray signal 102 and emits it. Since the signal is subject to time base extension in the circuit 26 and then modulated, a diode operated for a low frequency is adopted for the diode 29.
