Title: Image forming device
Inventor: EZU AKIHIRA
IPC: G03G15/00
Filed: 1989-03-13
Abstract: PURPOSE:To reduce selecting operations through keys, to lighten the burden imposed on an operator, and to prevent wasteful copying caused by misoperation by performing a magnification priority processing and a paper selection priority processing when an identifying means identifies a first color and a second color, respectively. CONSTITUTION:Marks Mb and Mr are recorded on a document D with the first or second color beforehand, and the identifying means 171 identifies the marks Mb and Mr at the time of image formation. When the means 171 identifies the first color, a magnification changing means 8 is actuated so that a magnification matches the size of a selected image-formed medium P, thereby performing the magnification priority processing; when the means 171 identifies the second color, a selecting means 304 is actuated so as to select the image- formed medium P matching the size of the document D detected by a detecting means 53, thereby performing the image-formed medium selection priority processing. Since selecting operations through keys are minimized, the burden imposed on an operator can be lightened, and wasteful copying caused by the misoperation can be prevented.

Title: Coagulation and filtering operation
Inventor: YOSHII YOUICHI
IPC: B01D29/00
Filed: 1979-05-16
Abstract: PURPOSE: To effect a fast coagulation and filtering operation by a method wherein an aluminum based coagulant is added at a speicified pH to form coagulated material.  
     CONSTITUTION: An aluminum based coagulant such as aluminum sulfate, aluminum chloride, polyaluminum chloride or the like is added to water to be treated. At the same time HCl, etc. is added to form coagulated material in acidic region of pH 4.5W6.0, preferably pH 4.8W5.7. This method of forming coagulated material on an acidic region reduces pressure drop in a high-speed filter operation and increases the amount of trapped suspension. The process also eliminates the need of pH adjustment to neutral region by adding alkalis when addition of coagulant decreases pH of water to be treated.

Title: Controller for revolution speed of fan of air conditioner for vehicle
Inventor: OGIWARA YOSHIYUKI
IPC: F24F11/76
Filed: 1981-04-20
Abstract: PURPOSE:To prevent the unnecessary rise in the revolution speed of a fan from being caused by the temporary change in the temperature of a vehicle room, by keeping the revolution speed of the fan at the minimum after the temperature of the room has reashed the vicinity of a set level, until the difference between the room temperature and the set level exceeds a predetermined value. CONSTITUTION:When the difference Ts-Ti between a set level and the temperature of a vehicle room has become smaller than a prescribed value T1, a comparison and calculation circuit 8 sends out a signal ST1 to a discriminator 14 to shift switches 10, 11 to bring their movable contacts 10c, 10d, 11c into touch with fixed contacts 10b, 10b', 11b. As a result, though the circuit 8 stops sending out the signal ST1 to the discriminator 14, the switches 10, 11 remain shifted to keep the revolution speed of a fan at the minimum until the difference Ts-Ti becomes larger than a signal T2 from a reference voltage generation circuit 13. When the difference has exceeded the signal T2, the movable contacts 10c, 10d, 11c of the switches 10, 11 come into touch with fixed contacts 10a, 10a', 11a to apply a signal to a fan motor 7 through an amplifier 5 and a drive circuit 6 to continue the controlled rotation of the motor until the difference becomes the prescribed value T1.

Title: Phase locked loop circuit
Inventor: TAKAHASHI AKIRA
IPC: H03L7/10
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To obtain a phase locked loop circuit in which no phase jump is caused for an output phase synchronizing signal in the case of switching a reference signal for phase locking and no out of frame synchronism is caused in an opposite device. SOLUTION: When a reference signal switching circuit selects a new reference signal from a reference input terminal 1a, phase locking control is stopped by a free run control signal 5 to cause free running. Thus, tri-state buffers 13a, 13b of a charge pump 6 reach a high impedance state, then an output level of the charge pump 6 is given by resistors 14a, 14b and a voltage controlled oscillator 9 outputs a frequency in the vicinity of the frequency substantially to be synchronized. In this case, since no phase lock control is conducted strictly, a phase of an output phase locking signal is slowly changed and the phase locking control is restarted when the phase of the output phase synchronizing signal is closer to the phase of the new reference signal.

Title: Porous exothermic body
Inventor: IMURA KOICHI
IPC: H05B3/14
Filed: 1992-02-18
Abstract: PURPOSE:To enhance heat transfer efficiency by employing a porous exothermic body which is of a three dimensional net work structure made of PTC material where its porosity lies in a specified range, each opening diameter of its net work structure lies in a specified range in the unit of mum and no through-hole exists along the skeleton of the three dimensional net work structure. CONSTITUTION:A porous exothermic body is so constituted that its porosity is not less than 60% and not more than 98%, each opening hole diameter of a net work structure is more than 50mum and not more than 5000mum and no through-hole is available along the skeleton of the three dimensional net work structure. A mixture including PTC raw material is thereby frothed and sintered as it is in a frothed state. Sintering the material with its frothed state maintained permits the porous exothermic body to be formed, which has no through-hole along its skeleton. This thereby allows a three dimensional net work structure which has a little or almost no hollow skeleton while sufficient strength is being maintained, to be formed in full detail, so that its contact area is made large. By this constitution, heat transfer efficiency can be enhanced.

IPC: G11B27/10
Filed: 1986-03-19
Abstract: PURPOSE:To eliminate a waste of time due to a wrong setting by easily setting a disk number, a data number, etc., without any mistake. CONSTITUTION:When a disk 12 is selected in a disk storage section of a tray 13 based on an externally set disk No. whether there is the disk 12 or not is detected and stored and when the selected disk 12 is reproduced based on an externally set music No., TOC data stored on the disk 12 is read and stored. Then it is decided whether the externally set disk No. is already set before or not and when so, the disk No. and music No. are collated with the storage contents to display a wrong set number. Consequently, even if a wrong number is set externally, it can be corrected immediately, so the setting operation is facilitated and a waste of time due to the wrong setting is eliminated.

Title: Tape cassette
Inventor: SHIOMI YOSHINORI
IPC: G11B23/087
Filed: 1984-03-28
Abstract: PURPOSE:To prevent the leakage of the rubbing powder, if produced between a coil spring and boss, to outside by setting a coil spring which energizes a tape guide member toward a lower case at a position enclosed by a boss set to the inner wall of an upper case and a hole formed to the tape guide member. CONSTITUTION:A coil spring 18 which energizes a tape guide member 13 toward a lower case 6 is set at a position enclosed by a boss 16 set to the inner wall of an upper case 4 which guides and supports the member 13 and a hole 15 through which a boss of the member 13 for insertion of the boss 16 is put. This eliminates a new space for the spring 18 and therefore functions can be added without increasing the height. Furthermore the rubbing powder, if produced between the spring 18 and the boss 16 due to the up-down movements or vibrations of the member 13, can be prevented from leaking outside. This ensures the stable video record/reproduction at all times.
