Patent JP-S59185498-A (JP)
Title: Loudspeaker device
Inventor: KITOU KOUJI
IPC: H04R3/04
Filed: 1983-04-06
Abstract: PURPOSE:To raise a distortion reducing effect at the time of a large output by setting the center pole of a loudspeaker to a length of such an extent that its height exceeds the upper end face of a voice coil in a motional feedback type loudspeaker device. CONSTITUTION:A center pole 25' is made longer by a length H than the upper end face of a voice coil 24. The length H is made almost equal to the maximum amplitude which is forecast at the time of the maximum output sound pressure level. Therefore, even in case of a large amplitude at the time of a large output, the pole 25' is always in the coil 24, therefore, the inductance of the coil 24 is scarcely varied. Also, heat escapes easily to the pole 25' from the coil 24, and the temperature of the coil 24 falls. As a result, the variation of a resistance R of a woofer unit 8' and an inductance L becomes as shown by 30' and 31', respectively, and even at the time of a large output, an equilibrium condition of a bridge circuit is almost formed. Therefore, an exact speed signal is obtained, and distortion reducing effect by a speed feedback can be displayed sufficiently.

Inventor: SAKAI KIYOSHI
IPC: C07D407/12
Filed: 1993-02-25
Abstract: PURPOSE:To obtain a new compound useful as a synthetic intermediate for a therapeutic agent for hyperlipemia such as compactin or mevinolin. CONSTITUTION:This compound is expressed by formula I (R1 is protecting group of OH selected from tetrahydropyranyl and acyl), e.g. (2aSR,5aRS,6RS,8 aSR,8bSR)-2a,3,5a,6,7,8,8a,8b-octahydro-3-oxo-6(tetrahydropyran-2-yl) oxy-2H- naphtho[1,8-be]furan-2-one. The compound expressed by formula I is obtained by subjecting a Z type olefin expressed by formula II (THP is tetrahydropyran-2- yl) to the basic cyclizing reaction in a solvent (e.g. THF). Since this compound expressed by formula I is capable of providing a compound keeping a state of the same steric configuration as that of compactin is obtained in introducing various substituent groups (R) into the 1-position of the naphthalene skeleton, the compound is convertible into an intermediate for synthesizing the compactin, etc., or its derivative.

Title: Copying device
Inventor: NAKAMURA SHINICHI
IPC: G03G21/14
Filed: 1988-03-14
Abstract: PURPOSE:To reduce power consumption without lowering the maximum copying velocity of a copying device by making the incoming velocity of an optical system lower than that in a copying time adjusting to a time necessary for the exchange of originals. CONSTITUTION:When the time necessary for the exchange of the originals is longer than the time necessary for the incoming action of the optical system, a CPU in a controller judges a timing for the exchange of the originals and commands an I/O output 807. The output 807 outputs a reference frequency 812 for determining the incoming velocity of an optical motor to an optical motor controller 110 at a frequency lower than the frequency at the time of usual copying so as to make the incoming velocity low. As a result, a current flowing in the optical motor 115 can be made small and a peak current at the time of inversion can be kept low. Thus, the current fed to the optical motor can be reduced and the power consumption can be suppressed without lowering the maximum copying velocity of the device.
