Title: Slide boat for liquid growth
Inventor: KONO KENJI
IPC: H01L21/208
Filed: 1986-02-20
Abstract: PURPOSE:To use substrates having different thicknesses by elevationally moving substrate bases upward or downward by the movement of a gap regulator and regulating the depth of a hole for containing the substrate on which a semiconductor crystal is grown. CONSTITUTION:The bottom 11a of a substrate base 11 is tapered, and contacted with the tapered surface 12a of the surface of a gap regulator 12. When the regulator 12 laterally moves rightward or leftward, the base 11 contacted with the regulator elevationally moves since the bottom 11a is tapered to thereby vary the depth of a hole 16. Thus, the hole 16 can contain substrates of various different substrates, and semiconductor crystals can be preferably grown on the substrates having different thicknesses with one set of boat base 13 and a slide boat 16. In order to clamp the regulator, clamping screws 14 are used, the depth of the hole 16 is set, and the regulator 12 is clamped so as not to move.

Title: Method of controlling pressure in evaporating drum of evaporator
Inventor: FUKUMOTO KATSUTOSHI
IPC: F17C13/02
Filed: 1980-03-19
Abstract: PURPOSE:To accomplish stable control on the operation of an evaporator for wide and rapid change of the load, by changing the sensitivity of a system for controlling the pressure in an evaporating drum according to the temperature difference of heating medium at the inlet and the outlet of the same. CONSTITUTION:When an evaporator is operated under a high load and the temperature difference of 15 deg.C at the inlet and the outlet of hot water, it is operated under an optimal controlling condition by correcting the output of a function operator 13. In this state, if the load is lowered rapidly, pressure in an evaporating drum is raised slightly, so that output of a subtracter 11 is lowered and that of a function operator 13 is also lowered. Consequently, output of a multiplier 12 and that of a pressure regulator 17 are both lowered. This causes reduction in the  opening of a control valve 21, so that the rise of the pressure in the drum can be  prevented. Thus, it is enabled to accomplish stable control against wide and rapid change of the load.

Title: Color cathode-ray tube
Inventor: HIROTA KOJI
IPC: H01J29/32
Filed: 1985-02-25
Abstract: PURPOSE:To further reduce the error of beam landing resulting from the thermal expansion of a shadow mask by properly selecting the width of black films located at given intervals and the distance between phosphor layers partly located on the black films. CONSTITUTION:The inner surface of a panel 5 is coated with black films 1 regularly arranged at given internals to form openings. These openings are regularly filled with red, green and blue phosphor layers 2R, 2G and 2B which are located at intervals (D). Heat 61 radiated upon those areas of a thin aluminum layer 13 located over areas of the black layers 1 not coated with the phosphor layers 2R, 2G and 2B undergoes irregular reflection thereby reducing the amount of reflected radiation heat returning to a shadow mask 4. Therefore, the temperature increase of the shadow mask 4 is reduced and as the result the error of beam landing is minimized. It is possible to improve the error of beam landing by 15-20% by satisfying the formula of W/3<=D<=W-20mum.

Title: Energy spread signal elimination device

IPC: H04N5/16
Filed: 1991-02-28
Abstract: PURPOSE:To realize a sufficient elimination rate to plural spread signals and to avoid the device from being depending on a signal form by discriminating the amplitude and the frequency of an energy spread signal and generating an elimination signal depending on the discrimination. CONSTITUTION:A video signal including an energy spread signal is fed to an input terminal 100 and inputted to a superimposing circuit 101 and an LPF 107. The superimposing circuit 101 receives an elimination signal of an opposite phase to that of the energy spread signal from a changeover circuit 104. The energy spread signal extracted by the LPF 107 is inputted to an S/H circuit 108, in which the signal is sampled and held. A microprocessor 110 obtains the amplitude and frequency information of the energy spread signal based on a difference between a high peak and a low peak and its period outputted from the S/H circuit 108. The amplitude and frequency of the elimination signal given to the superimposition circuit 101 are selected based on the obtained amplitude and frequency information to increase the reduction rate of the energy spread signal.

Title: Radio receiver
Inventor: TAURA KENICHI
IPC: H03J7/18
Filed: 1982-03-03
Abstract: PURPOSE:To obtain an identity discriminator which is used for two sound signals of the same content and opposite phase, by converting an integrator output biased to negative side into a positive voltage when the signals are the same content and opposite phase with an absolute value amplifier, relating to a car radio receiver. CONSTITUTION:The absolute value amplifier 39 is an amplifier in this case, which gives a positive output when the input is positive, gives also positive output even if the input is negative, and has almost equal gain with different polarity to the output to positive and negative inputs. Taking the gain about 1, since the output e0 of the integrator 37 has a positive voltage around a maximum value when it is the same content and in-phase, and the output e0 has a negative voltage around a minimum value when it is the same content and opposite phase, then the value is represented with a positive voltage around the maximum value in both cases. Since the output e0 is almost zero as to the two sound signals having different content, a voltage comparator 38 provides the discrimination output of coincidence and discidence by comparing a discrimination voltage eth determined suitably with an output voltage of the absolute amplifier 39.

While referring to the contents of characteristic table stored and held in a characteristic table storage means 119, a processing time predicting means 120 calculates the predictive processing time of job data as the object of processing time prediction based on their features provided by the feature discriminating means 112.

Title: Input signal holding circuit
Inventor: ARAKAWA HIDEKI
IPC: H03K3/356
Filed: 1984-02-28
Abstract: PURPOSE:To improve the noise immunity by obtaining an overlapped period so that a voltage of one node is high and a voltage of the other node is at a prescribed level or over in an input signal holding circuit having noise immunity. CONSTITUTION:When a noise having a pulse width shorter than a normal pulse width is impressed and a write enable signal -WE goes to a low level, a level of a node N1 goes to high and the level of a node N3 remains high and is unchanged. The signal of the node N1 is delayed and the signal of the node N2 is changed, but the signal of the node N1 goes to a low level after a time tau. Since the relation of time tau > time tau' exists, the level of the node N1 is low before the level of the node N2 goes to a high level and the level of the node N4 is kept low and unchanged. Thus, the level of the node N3 is kept high and unchanged.
