Title: High speed packet and frequency switch
Inventor: ANTONEERA DANIEERU
IPC: H04B10/291
Filed: 1990-07-19
Abstract: PURPOSE: To improve flexibility in a network by permitting only a stream to be transmitted to a corresponding fiber leading to an outside from a switch within various kinds of frequencies obtained by the frequency conversion of respective optical packet streams. CONSTITUTION: The optical stream g1 of the extracted packet is transmitted to a passive power divider SS1 and divided into m-number parts so as to be introduced by a frequency conversion block FK11. One of the packets is converted into the frequency which is assigned to be the same as the one in the fiber leading to the outside from the switch and the whole remaining ones are converted into an annulment frequency. Then, the packet k11 of the new frequency is combined again in order to form the stream in output optical fibers u1-un together with the packets k12-k1n from another frequency conversion block in a passive re-combining device. Thus, flexibility is enhanced in the communication network.

Title: Proportional electromagnetic system direction controlling valve with manual operation mechanism
Inventor: SHIMOURA KENICHI
IPC: F16K31/11
Filed: 1982-10-28
Abstract: PURPOSE:To improve lightness and reliability of a manual operation by attaching a pilot valve to a movable iron core of a solenoid such that voltage is not applied to the solenoid in the manual operation to avoid the action of pilot pressure. CONSTITUTION:Since solenoids 28a, 28b are both not excited in manual operation, a lever 15 is operated. When a main spool 2 is moved in the direction E, a piston 7b is also moved in the direction of E and the spool 2 is lightly moved only against the repulsion of a manual lever operating return spring 13 until the spool 2 abuts against a piston 7a. Also, when voltage is applied to the solenoid valve 28b, a pilot valve 18b attached to a movable iron core 29b is pressed against a valve seat 27b by a force corresponding to the applied voltage, and pressure in a return spring chamber 19b and a pilot pressure chamber 9b is increased in proportion to the force pressing the pilot valve 18b against the valve seat 27b. As a result, the pistons 7a, 7b are pressed against both ends of a piston fit portion 6 and moved to the pilot pressure chamber 9a side together with a main spool connecting member 3 so that the spool 2 is also moved in the direction E at the same time.

IPC: C21D9/52
Filed: 1981-11-27
Abstract: PURPOSE:To prevent surfaces of a steel plate from damaging owing to contact with impellers by providing rings which have greater outer diameter than the maximum diameter formed by impellers in rotation and the same axial core to the rotating shafts of the impellers. CONSTITUTION:Impellers 36 and 38 of a successive steel-plate quenching device each have four blades 40 projecting from the outer circumference radially at equal intervals.

Abstract: PURPOSE:To reduce the necessary area and electrostatic capacity as compared with a semiconductor device having a conventional stabilized resistance by forming a polysilicon between an electrode and an emitter region or a base region, forming high and low density impurity layers in the upper and lower portions, and forming the two layers in a stabilized resistance. CONSTITUTION:A P type base region 4 and an N type emitter region 3 are formed on an N type semiconductor substrate 7, a polysilicon layer which contains 10<18>-5X10<19>atoms/cm<3> of phosphorus is formed in 3,000Angstrom  of thickness on the contact of the region 3, an arsenic is implanted to the surface under the conditions of 50keV, 3X10<14>-2X10<16>atoms/cm<3> to activate the arsenic implanted to 750 deg.C. Then, emitter electrodes 1, 2 are formed on a polysilicon layer 8, and the ohmic resistance (10<-3>-10<6>OMEGA/cm<3>) of the surface high density layer and the high resistance (10-0.05OMEGAcm) of the intermediate layer are used as series resistance for a current flowed to the region 3. Thus, a diffused region for a ballast resistance can be eliminated on the substrate 7 to reduce the chip size. Since the bonding capacity between the substrate 7 and the ballast resistor can be eliminated, it can prevent the high frequency characteristic from deterio rating.

A handle 4 rotating in the directions shown in the arrows 10 while keeping a shaft 9 as a supporting point is provided on the upper surface of the door 1. Now, when the handle 4 is pushed to the direction shown in the arrow 7 with a hand, a piece 11 slid on the lower end of the handle is moved in the direction reverse to the direction pushing the handle 4 and thereby a supporter 5 is pushed. Therefore force is given to the door 1 in the direction shown in the arrow 7 and the bearing 6 on the rail 3 and the door 1 is opened by small force. The opening and closing mechanism of the door is small and therefore a separator main body is miniaturized and operability is improved.

Title: Temperature controller for electric carpet
Inventor: SUZUKI TAKAHARU
IPC: G05D23/24
Filed: 1985-08-30
Abstract: PURPOSE:To enable an appropriate temperature control by detecting the leading time of the surface temperature of a surface-like main body and room temperature so as to decide the presence or absence of a cover or a rug and controlling temperature according to the presence or absence of the cover. CONSTITUTION:As the carpet is conducted, its surface temperature slowly increases. However, its increasing speed depends on room temperature, and the time until the prescribed temperature is attained is longer as the room temperature is low. When the cover or rug is laid on the carpet, the temperature speedily rises because heat is hardly lost out of the surface of the carpet. A microcomputer 11 calculates a curve C as the function of the room temperature from the room temperature and the leading time, both of which are detected by a thermister room temperature sensor 4. If the leading time is longer than the decision value, it is decided that the cover is not provided. And if not, it is decided that the cover exists. Based on the decided result, the microcomputer 11 controls temperature so as to attain an appropriate surface temperature.
