Title: Image forming device
Inventor: ITO HIROSHI
IPC: G05D23/19
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To obtain an image forming device by which the temperature of a fixing device is excellently maintained without lowering the copying speed even in the case of successively forming images, on the paper of a comparatively large size by devising the temperature control of the fixing device. SOLUTION: In the case of successively making copies of one hundred or more sheets of A3-sized paper, the standby temperature of a heat roller 11 before starting the copying is raised to a high standyby temperature. For instance, when standard standby temperature is 195 deg.C, the standby temperature of the heat roller 11 is raised to be at 205 deg.C, which is the high standby temperature. Then, the copying is started after the standby temperature of the heat roller 11 is raised. Thus, since the standby temperature of the heat roller 11 is high, the temperature of the heat roller 11 is hardly lowered though successive copying is executed on the A3-sized paper that is a large sized paper, so that the copying is successively executed at a specified copying speed.

Title: Device for estimating distance of ship approaching to pier in ship guide system for approach to pier
Inventor: SHIMOKAWA ITSUO
IPC: G08G3/02
Filed: 1981-09-02
Abstract: PURPOSE:To attempt at safety in guiding a ship in approach to a pier and improve reliability  by judging abnormality if change in the acceleration of the ship approaching a pier based on  measured distances by means of an ultrasonic wave or others is more than the specified acceleration and estimating the distance of the ship from the immediately preceding measurement value. CONSTITUTION:The distance to a ship 1 approaching a pier and the speed of ship by the  change in the distance to the ship are measured by means of an ultrasonic wave sending and  receiving device 2 that is immersed in the water at a dolphine pier 3, and measured distances are stored in a distance memory 18 through a counter 17 and the speed is written in a memory 21 through a velocity counter 20. An abnormal value judging circuit 30 calculates the  approaching speed of the ship to the pier by the difference of the contents of the counter 20 and memory 21. If the change in the acceleration is more than a specified acceleration, the  abnormality judgement signal is input to a distance estimating circuit 40. The circuit 40 upon  receiving the signal calculates for estimation the distance of the ship 1 based on the memory  contents immediately before that are stored in the memories 18 and 21. Accordingly misjudgement of approaching to the pier due to noises developed by the measurement of, for instance,  a tug boat in the vicinity can be avoided and safety in the guiding of the approach to the pier  and increased reliability can be thereby attempted.

Title: Servo circuit of digital disk player
Inventor: TOMIDOKORO SHIGERU
IPC: G05D3/12
Filed: 1982-08-09
Abstract: PURPOSE:To reduce the effect of a mistrack signal, etc. without lowering the loop gain and to ensure stable servo control, by limiting the level of a frequency component higher than a prescribed frequency among error signals and delivering a signal component having a low frequency with no limitation to correct an error in response to the signal of a low frequency. CONSTITUTION:When a tracking error signal has a frequency lower than a prescribed level, the normal servo control is given to the error signal with no attenuation given through an attenuating circuit 22. When an error signal has a high frequency, the error signal is differentiated and compared with a reference level. If the error signal has a level higher than the reference level, a comparator 24 drives the circuit 22 to attenuate the error signal and then to lower the dynamic range. In this case, no servo control is carried out. The tracking error signal has the higher level of frequency as the scale of error increases. Therefore, a servo system performs no servo control if a mistrack signal is produced and the frequency of this signal is higher than a prescribed level. As a result, it is possible to increase the loop gain by increasing the response frequency of of the servo system.

Abstract: PURPOSE:To obtain the composite body having a homogeneous foaming structure with spherical foams by a method wherein the liquid foaming material discharged behind a facing material is dispersed all over the back surface through a lining material and then is filled into the remaining part by a special structure stepwise when it is foaming. CONSTITUTION:The facing material 1 such as an iron plate etc. is fed by a feeding mechanism 4 and liquid foaming material 6 such as polyurethane and the like is discharged from a discharger (a) behind the facing material. The foaming material 6 is pressed by a dispersing roller 7 while being cleamy yet through a lining material 2 such as the craftpaper and is dispersed on 80-100% of the area of the foamed body formed at the back. During the gel time when reaction and foaming is made, the remaining 10% or thereabouts (another 10% foams or disperses after passing the roller 7) disperses at the position of a correcting roller 8 to fill 40-60% of the whole capacity. Thus, the foam structure is forced to be deformed and pressed so that 20% of the capacity is filled before it reaches dies 10, 11. At the inlet part of the dies, 20-40% of the remaining capacity is filled before the end of the gel time and the rise time is completed to obtain the adiabatic composite plate.
