CONSTITUTION:Low expansion glass having (30-55)X10<-7>cm/cm deg.C coefft. of linear expansion is obtd. by admixing at least one optional component selected from each <=5.0wt% R2O (R is alkali metal), SrO, BaO, ZnO, PbO, TiO2, and ZrO2, <=10wt% CaO, and each <=3.0wt% Ta2O5, Nb2O5, WO3, La2O3, Y2O3, and Gd2O3, and 2wt% at least one defoaming agent selected from As2O3, Sb2O3, (NH4)2SO4, NaCl, etc. to a fundamental compsn. consisting of 45.0-65.0wt% SiO2, 5.0-15wt% B2O3, 15.0-25.0wt% Al2O3, and 5.0-15.0wt% MgO, with 0.63-1.79 molar ratio of MgO/Al2O3, vitrifying by melting at 1,470-1,500 deg.C, then forming at 1,150-1,250 deg.C.
Patent JP-H04124491-A (JP)
Title: Rotary compressor
Inventor: IIZUKA TATSUYUKI
IPC: F04C18/356
Filed: 1990-09-13
Abstract: PURPOSE:To obtain a rotary compressor excellent in abrasion resistance by not applying surface treatment to the slide contact face, with a vane slot part, of a vane, thereby minimizing hardness difference between the vane and a cylinder. CONSTITUTION:Surface treatment 6 is not applied to the sliding face 7, with a vane slot part 3, of a vane 2. When a rotary compressor starts its compressing action, pressure is generated to the sliding face 7, with the vane slot part 3, of the vane 2, and this pressure causes the sliding face 7 to be pressed to the vane slot part 3 and worn. However, since surface treatment is not applied to the sliding face 7, the hardness difference between the sliding face 7 and the vane slot part 3 is small, and therefore the vane slot part 3 is not easily chipped by the vane 2. The abrasion of the vane slot part 3 is therefore extremely small, thus preventing an adverse effect on a performance characteristic.

IPC: H01L25/11
Filed: 1994-10-12
Abstract: PURPOSE: To obtain a lightweight and compact semiconductor stack employing an insulation band for facilitating the press contact, while sustaining the press contact force for a long term, by setting a specific relationship between the radius and the thickness of plate at the curved part of the insulation band. CONSTITUTION: In order to retain a resilient press contact force in a semiconductor stack, a predetermined press contact force F is applied by means of a press and then a press rod 15 is lowered until coming into contact with a stopper seat 13 while a lock nut 18 is driven upward until coming into contact with the open surface of a U-shaped block. Although the insulation band 23 is not subjected to tensile force under that state, a tensile force F is applied to the race track type insulation band 23 as a reaction to the press contact force upon removal of the press and fracture due to tensile force is determined, by experiment, at the border of the curved part and the linear part of the insulation band 23.  An optimal insulation band could be constituted by setting the radius at the curved part of the insulation band 23 susceptible to the capacity of the semiconductor stack in the range of 2-12 times of the plate thickness at the curved part.

Title: Reception circuit for radio machine
Inventor: OGE AKINORI
IPC: H04B1/18
Filed: 1992-09-16
Abstract: PURPOSE:To easily optimize the input impedance by providing an emitter current control means which varies the emitter current of a transistor TR which amplifies an inputted signal. CONSTITUTION:An emitter current control means alpha consists of a variable current source 10 and if a current mirror pair consisting of TRs Q2 and Q3 and resistors R1 and R2. When the quantity of the charging current from a terminal 8 is changed by the variable current source 10, the emitter current of the TR Q1 is changed. When the emitter current is changed, the voltage between the base and the emitter of the TR Q1 is changed, and the junction capacity between the base and the emitter is changed. Then, the input impedance is adjusted. Thus, the input impedance is optimized without adjusting an input matching circuit 2 and degrading the reception sensitivity in the frequency band of a reception signal.

IPC: B60Q1/06
Filed: 1988-09-30
Abstract: PURPOSE:To provide adjustability for optical axis by reference to the car body by turning a headlight so that indeces of at least three points in total furnished at the headlight and on the body side are collimated on one straight line. CONSTITUTION:When aiming adjustment of a headlight 1 in the direction left and right is to be performed, checking is made with ocular collimation whether the line tying a collimating antenna 17 outside the car body in its transverse direction with another collimating antenna 15 is identical to the reference graduation 0 on a reference plate 19. When this line tying the two antennae is identical to the graduation 1 on the same plate 19, it signifies that the optical axis of the headlight 1 is dislocated to the left from the target position for the optical axis, and therefore an aiming screw is turned to tilt rightwise the headlight 1 with the rotary shaft of the collimating antenna 15 as the axis of tilting, and adjustment is made so that the reference graduation 0 on the reference plate 19 becomes identical to the two collimating antennae 17, 15. Thus the optical axis adjustment of the headlight in the direction left and right can be accomplished very easily by reference to the car body.

Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To obtain a practical system model optimal to power flow calculation by approximating a reactive power Q in the constant output control of an effective power P, i.e., the output from a power supply model where induction generators are linked with a system as distributed power supplies. SOLUTION: Assuming the primary effective power P1 is constant in constant output control of an induction machine type distributed power supply model, primary reactive power Q1 outputted from the induction machine type distributed power supply model is approximated by the product of a coefficient a2 and the square term of a voltage v at an link node, the product of a coefficient a1 and the linear term of the voltage v, and the product of a coefficient a0 and the 0 power term of the voltage v. According to the method, power flow calculation for determining voltage/current distribution of a system can be carried out at a higher speed with higher efficiency when distributed power supplies are introduced in a power flow calculation method for radial system where a distribution system model is built in the forward calculation.
