Abstract: PURPOSE: To dry grains uniformly by making dropping ports meet with an opening of a supply port for dropping grains as moving a shutter member to corrospond to the intermittent drive of a let-out valve and equilizing the dropping time of grains of these dropping ports.  
     CONSTITUTION: Dropping ports 26aW16c with a position-ditecting switch LS 1  and others at hand are made to meet an opening or a supply port 29 for dropping grains as moving a shutter member 30 with a switch operation piece 44 via shutter-driving motor 32 with six stepping relay contacts in its circuit to correspond to the intermittent drive of a let-out valve (unillustrated). When th operation piece 44 is brought in contact with LS 1 , since the member 30 is positioned on this side of the dropping port 26a, the dropping port 26a is opened. When the operation piece 44 is in contact with either LS 2-1  or LS 2-1  and the member 30 is moved to close the dropping port 26a, the dropping port 26b is opened as meeting with the supply port 29. When the member 30 is further moved to bring the operation piece 44 in contact with LS 3 , dropping dorts 26a and 26b are closed, and grains can be dropped through the dropping port 26c.

Title: Light scanner for optical recording medium
Inventor: MIYAKE TAKAHIRO
IPC: G11B7/085
Filed: 1988-02-03
Abstract: PURPOSE:To successively access plural information tracks without a successive break by providing a changeover return means to switch a light source or a light path when a light beam reaches an end edge and to return the light beam to the start edge of scanning. CONSTITUTION:When a light beam A' reaches an end edge 2b on an information track 2 and a polygon mirror 5 is further rotated, a light beam A to be made incident is reflected by a next mirror 5a. At such a time, the light beam A' is instantaneously changed from a reflection angle smaller than an angle theta2 into the reflection angle larger than an angle theta1. For such a reason, the light beam A' is immediately returned to a start edge 2a on the information track 2, and the scanning of the information track 2 can be newly started. Since the light beam A' is always moved only in a scanning direction by repeating the above-mentioned action, the plural information tracks 2 can be successively accessed without passing a fly-back period.

Filed: 1979-03-02
Abstract: PURPOSE:To secure the data transmission with the highest transmission efficiency  by giving the control to the transmission telegram process block to indicate the  alteration of the transmission parameter in case the value of the negative answer detection circuit which is read out by the parameter detection circuit with every fixed time is larger than the prescribed level. CONSTITUTION:In case the transmission quality is detected at the transmitter side and in the communication control system which increases the transmission efficiency of the data communication circuit or the like, negative answer counter circuit 3 is started to perform the count-up when the negative answer is detected by negative answer detection circuit 2 out of the telegram received at telegram reception process block 1. On the other hand, timer circuit 4 starts parameter alternation detection circuit 5 with every fixed time, and thus circuit 5 reads out the value of circuit 3. And in case the value read out is larger than the prescribed level, transmission telegram process block 6 is controlled to indicate the alteration for the transmission parameter as well as reset circuit 3. As a result, the quality of the data communication circuit can be confirmed at the transmitter side and with every fixed time, thus ensuring the data transmission with the highest transmission efficiency for the transmission quality of each time.

Title: Video disk player
Inventor: KISO MATAICHIROU
IPC: G11B21/08
Filed: 1983-02-15
Abstract: PURPOSE:To exclude the effect of ambient temperature on position control by providing a temperature sensor near a suspension to apply the position control to an arm by an arithmetic output between a track control signal detected by a stylus and the output of the temperature sensor. CONSTITUTION:The temperature sensor 12 is provided to an upper part of the suspension. When the ambient temperature around the suspension rises, a voltage across a thermister 12A is decreased and an input voltage to a multiplier 17 is also decreased. Even if a track control signal inputted to an input terminal A of the multiplier 17 is unchanged, the output from the multiplier 17 is reduced, resulting that the controlled variable by coils 5a, 5b, 5c and 5d is decreased. In comparing the case at a reference temperature with that at the increased temperature, the rigidity of the suspension is decreased by the increase in the ambient temperature and the amount of movement of the arm 8 is the same as that at the reference temperature even if a control voltage given to each coil is less. That is, the amount of change in the elasticity of the suspension attended with the temperature change is corrected by an output of the temperature sensor 12 and control coils 5a-5d are controlled by a proper control voltage.

Abstract: PURPOSE:To realize the assured winding of a film for the automatic film loading mechanism of a camera, by forwarding the film by a sprocket until the film is wound up to a spool. CONSTITUTION:The tip of a film is put on a patrone 13, and the camera back cover is closed. Thus the preliminary film winding mode is secured with a motor 1 turning toward an arrow mark. A clutch lever turns counterclockwise, and a gear 7 bites the gears 8 and 9. A sprocket 19 turns with its projected part 18a pressed by an end 17b of a spring 17a wound round a gear 17 to forward the film. The turning speed of the spool having a friction surface and a film pressing roller is set a little higher than that of the sprocket. Thus the film is  driven by the spool after the film is wound up to the spool. The projected part  may possibly hit the spring end 17b at the opposite side 18b but just ride over  the end 17b since the side 18b formes a cam surface.
