Abstract: PURPOSE: To take out the remaining solid with high purity and effectively, by performing the primary separation of the solid and liquid under high pressure, then returning the pressure to the neighborhood of the atmospheric pressure and, in this way, melting a part of the specified component of crystalline state.  
     CONSTITUTION: Over and under the high-pressure vessel 3 of which at the inner face the heat-insulating layer 5 is equipped, the pistons 1 and 2 which are driven with an oil hydraulic pressure, are installed, and the pipes 6, 7 and 8 for drawing- out the compressed liquid to each of which the check valves 6a, 7a and 8a are arranged, are installed. Now, the substance 4 in which the solid and liquid coexist, which is held under high pressure using this apparatus, is compressed by operating the pistons 1 and/or 2, and the separated liquid is discharged 6, 7 and 8 outside the system. Then, the pressure of the vessel 3 is returned to the atmospheric pressure or the pressure at its neighborhood. As the result, a part of the crystal of the specified component is melted, so that the liquid impurities which have been sticked to the surface of the solid or entangled into the gaps among the crystals are washed and removed with the molten liquid. In this way, the remaining solid is prevented from being contaminated in the state covered with its own molten liquid, so that the solid of high purity can be taken out

Title: Cable fm automatic channel selection circuit
Inventor: WATABE ATSUO
IPC: H03J7/18
Filed: 1986-05-23
Abstract: PURPOSE:To simplify the operation at cable FM reception by applying automatic channel selection based on the output of an antenna changeover detector and a tuning detection circuit. CONSTITUTION:The antenna changeover circuit 6 detects that a cable FM switch is turned on and the tuning detector 8 is detected to be in nontuning state, only in this case, a control output is outputted from an AND circuit 7 to an automatic channel selection circuit 9, which is activated until a cable FM broadcast is received. In detecting the receiving state of a reception circuit 4 by the tuning detection circuit 8, the channel selection by the circuit 9 is stopped. The automatic retrieval is applied until the reception circuit is tuned by having only to switch the antenna switching circuit 3 to the position of the cable FM terminal in this way so as to receive the cable Fd broadcast. Thus, the operation at the reception of a cable FM broadcast is simplified.

Title: Blower
Inventor: TERAO TOSHIO
IPC: F24F1/00
Filed: 1981-07-30
Abstract: PURPOSE:To prevent a motor from being abnormally heated and to improve safety, by a method wherein a fixture, with which a bearing part of a motor for blast and for air conditioner is secured to a blower, is constituted by the use of a high-heat transfer substance so that it covers a bearing collar part and a blower body and forms a radiating part between it and the body. CONSTITUTION:Heat, generated at a body 8 and bearings 9, 9 by driving a blast motor 7, is transferred to a fixture collar part 14 of a fixture collar part 14 of a fixture base 12 through a vibration absorbing rubber 11. The fixture collar part 14 has a better thermal conductivity and a gap is formed between a fixture cover 16 and a collar part 19. Thereby, an enough radiation takes place, and additionally, a heat radiated from the motor body 8 is gradually dissipated through a heat dissipation part 15. This causes a base plate 1 to be reduced in temperature rise, and enables to perform a sufficient dissipation of a heat generated at the body 8 and the bearing 9, which results in preventing the motor from abnormal heating.

Abstract: PURPOSE:To prevent the chattering of vanes by a method wherein the changing rate of the projecting amounts of each vanes, projecting into a back-pressure chamber, is reduced to change accelerations acting on the vanes continuously and smoothly. CONSTITUTION:The configuration [X(theta), Y(theta)] of the inner peripheral surface A of a cylinder is formed in accordance with the formula I while the projecting amount 1(theta) of the vanes into the cylinder is expressed by the formula II. Here, the total sum of the projecting amount of the vanes becomes constant in a function expressed by the sum of cos(mtheta), sin(mtheta) and the higher harmonics (2mtheta, 3mtheta, 4mtheta,...). On the contrary, the sum of the projecting amounts of the vanes into the back-pressure chamber becomes constant also. Accordingly, the changing rate DELTAh (formula III) of the projecting amount of the vanes into the back-pressure chamber becomes zero at all times, the accelerations acting on the vanes are changed smoothly and the chattering may be eliminated by a method wherein the configuration of the inner peripheral surface of the cylinder is formed in accordance with the formula I .

Title: Digital broadcast receiver
Inventor: KINO TETSUO
IPC: H04N5/44
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To improve convenience at the time of retrieving a program chart by storing data related with a program viewed by a user, and editing and displaying the data as a viewing history according to a request. SOLUTION: An MPEG2 transport demultiplexer 20 separates a PSI data stream from a transport stream. The PSI data stream includes data necessary for a program chart(EPG) such as the information of a channel or a program. An MPEG2 decoder & OSD 22 converts character data constituting the EPG into a video signal, and this video signal is transmitted through a video encoder 24, and displayed as a video. When a user views a program, a CPU 28 prepares a viewing history including a broadcast date, channel, fee, genre, and broadcast content or the like for each program unit by referring to the EPG, and stores it. When the user requests the viewing history at the time of retrieving a program, it is displayed according to a desired sort key and sort order.

Title: Automatic focus controller
Inventor: AOI SHIGERU
IPC: G11B7/09
Filed: 1984-06-12
Abstract: PURPOSE:To keep constant a zero cross point of an automatic focus control signal by delivering a signal proportional to the output signal of a photoelectric converting means to a generating means for automatic focus control signal as a zero cross correction signal. CONSTITUTION:When the reflection factor is different on the surface of an optical recording medium, the total photodetecting quantity changes with photoelectric conversion elements 1a and 1b. Thus the voltage Ve delivered from an adder 9 is also changed. The output voltages Va and Ve of current/voltage conversion amplifiers 2 and 3 are changed together with change of the Ve. When an assembling error has different directions, a point B set before the zero cross correction is shifted to the right or left from a shown point A at the focused point of an objective lens. Then the voltage Vf is supplied to an input terminal at one side of an adder 5 as a zero cross correction signal. As a result, the zero cross point is fixed for an automatic focus control signal Vg delivered from the address 5. Thus it is possible to secure a proper signal at all times despite a change of the reflection factor.

Title: Control pattern setter
Inventor: KUZUHARA TAKESHI
IPC: G05B19/02
Filed: 1992-05-13
Abstract: PURPOSE:To simplify an internal controller by substituting element values of both ends of a first control element value, second control element values corresponding to them, and a detection value into one prescribed relation formula to obtain a desired second control element. CONSTITUTION:When a temperature Ti detected by a temperature sensor S1 is in the rage from T1 to T2, temperatures T1 and T2, pressures P1 and P2 corresponding to them, and a detected temperature Tx are substituted for Tm-1, Tm, Pm-1, Pm, and Ti of the formula (Tm and Tm-1 are temperatures in both ends of the temperature range including the temperature Ti and Pm-1 and Pm are pressure values corresponding to these temperatures). When the detected temperature is in the range from T2 to T3, T2, T3, P2, P3, and Tx are substituted for Tm-1, Tm, Pm-1, Pm, and Ti of the formula. Consequently, a CPU 13 only performs operation of numerical value substitution in a pressure arithmetic part 13b. Thus, a program to generate the relation formula is unnecessary, and the memory capacity is reduced.
