Title: Preparation of polyester and sorbic acid
Inventor: KAMEI NOBORU
IPC: C07C57/10
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To efficiently obtain a sorbic acid having a high hue. SOLUTION: When allowing ketene to react with crotonaldehyde, crotonaldehyde having a purity of 95 wt.% or larger is used as the crotonaldehyde supplied to the reaction system to prepare a polyester. In this process, unreacted crotonaldehyde is recovered from a reaction mixture obtained by allowing ketene to react with crotonaldehyde, and the recovered crotonaldehyde is optionally recycled in the reaction system. The α- vinylcrotonaldehyde content in the crotonaldehyde supplied to the reaction system is, e.g. less than 0.5 wt.%, and the para-aldehyde content in the crotonaldehyde supplied to the reaction system is, e.g. less than 0.5 wt.%. Sorbic acid having a high hue is efficiently obtained, e.g. by degrading the polyester, obtained through the above-mentioned process, using hydrochloric acid.

Even if the frequency of an injected signal is changed between the injection synchronous ranges, the free oscillation frequency of the signal outputted from the oscillation circuit part 15 is made to follow the frequency of the injected signal. The phases of the injected signal and an injected synchronizing signal can always kept in a prescribed relation.

Title: Touch control system for carrying object
Inventor: HARADA EIICHIRO
IPC: G05D3/00
Filed: 1987-11-02
Abstract: PURPOSE:To improve the working accuracy by absorbing the speed fluctuation of a carrying object and secuting a touch between a working tool and a fixed position of the carrying object. CONSTITUTION:In case the speed vij of a carrying object 2 has fluctuation within a range of vi1-vi2, the start time of a working tool 3 has a change within a range of ti-ti'. Thus the touch points th1-th1' can be maintained at a fixed position with a distance 2l0 secured from a base point S1 in case a passing position sensor 41 is set at the point S1. As a result, the tool 3 can follow the speed fluctuation of the seed vij of the object 2 if produced. Thus a touch is secured between the tool 3 and a fixed position of the object 2 and the working accuracy is improved.

Title: Driving dircuit for display panel
Inventor: ARIMOTO HIRONOBU
IPC: G09G3/291
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To drive an independent electrode at a low voltage and low frequency by applying a reset pulse of the polarity reverse to a display panel in the interval of application of the display pulse in a common electrode. SOLUTION: A reset pulse has the polarity reverse to a display pulse and a magnitude of the same voltage as the first step pulse (6). This voltage is, for example, 160 V, which is the voltage for performing a discharge when a wall charge is left. Thus, the residual wall charge is surely discharged. Further, the same voltage is set, whereby the driving circuit can be simplified. The reset pulse requires a length capable of performing a sure discharge when the wall charge is left after the discharge is ended. To perform the sure discharge, about 5 μsec is necessary for this device. As to the time of discharge, the reset pulse is preferably inserted after the lapse of about 15 μsec from the fall of the display pulse to 0 V (GND).

Title: Self-propelled thresher
Inventor: NOGUCHI HIROTOSHI
IPC: A01F12/00
Filed: 1989-10-24
Abstract: PURPOSE:To enable to perfectly discharge residues such as grain dusts and facilitate the maintenance of the thresher by pivotally supporting either of the front and rear ends of the thresher on a hinge, permitting the other end to vertically rotate and winding a belt between a receiving pulley on an intermediate shaft near the hinge and an output pulley to transmit the power to the respective portions of the thresher. CONSTITUTION:After a threshing work is finished or when the inspection of a thresher is arbitrarily required, a cylinder for vertical movement is elongated to incline the thresher wherein the front side 7 of the thresher is high and the rear side is low because the rear end 6 of the thresher 3 is pivotally supported on a hinge 8. Since a receiving pulley 19 is disposed near the hinge 8, the rotation power of an engine can be smoothly transmitted to a threshing cylinder, a winnower, a shaking trellis, the first conveyer, the second conveyer, a straw-discharging cutter, etc., even under the inclined state, thereby permitting to perfectly discharge residues such as grains clogged in the thresher 3 from the rear portion of the thresher 3. The maintenance, such as inspection, cleaning and repairing, of the thresher 3 after the finish of the threshing work can be readily performed.

Title: Magnetic recording medium
Inventor: TSUGANE YOSHIHITO
IPC: G11B5/738
Filed: 1987-10-31
Abstract: PURPOSE:To improve an overwrite characteristic and to obtain excellent durability by incorporating nonmagnetic particles of specific sizes into a magnetic layer and projecting the nonmagnetic particles at specific ratios from the surface of the magnetic layer. CONSTITUTION:The nonmagnetic particles having 0.2-0.5mum average grain size are incorporated into the magnetic layer and are projected from the surface of the magnetic layer at 0.01-0.5mum<2> ratio per 1mum<2>. A primer coating layer having the film thickness larger than the film thickness of the magnetic layer is formed on this magnetic recording medium and, therefore, the surface characteristics of the magnetic layer are not impaired even the film thickness of the magnetic layer is reduced. Since the magnetic layer is thin, the overwrite characteristic is improved; in addition, part of the nonmagnetic particles project partially on the surface of the magnetic layer and adequately polish the surface of a magnetic head. Friction is thereby decreased and the good traveling property and durability are obtd.

Title: Semiconductor memory and bit line selecting method therefor
Inventor: HASHIGUCHI AKIHIKO
IPC: G11C7/00
Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor memory in which a short cycle time can be realized with low power consumption and a bit line selecting method therefor. SOLUTION: With regard to external column address and row address RA, the column address is decoded first to produce a column select signal CSD which is then latched at same timing as the row address RA. The latched column select signal CSD is inputted immediately to a column select circuit CS in order to precharge a bit line BL designated by the column address. The row address RA is decoded by means of a row address decoder RDC and a word line WL designated after decoding is activated. Since the decoding time of column address is excluded from the memory cycle, a short cycle time can be realized with low power consumption.
