Title: Hot wire type air flowmeter
Inventor: TSUTSUI MITSUKUNI
IPC: G01F1/68
Filed: 1983-10-26
Abstract: PURPOSE:To measure the flow rate of passing air accurately even though the temperature difference is yielded between the inside and the outside of intake air path, by providing the approximately same coefficient of thermal conductivity at a point, which is contacted with the intake air, in the output transmitting part of each heat sensitive element. CONSTITUTION:A hole 17 is provided in a holder 15 for a CW pin, which holds the output transmitting part of a cold wire 2 that is inserted into a conducting circuit. The cold wire is provided at a position, where air, which is heated by a hot wire 1, does not pass. An interval LH between the hot wire 1 and the holder 15 is made equal to an interval LC between the cold wire 2 and the holder 15 without enlarging the size of a bypass 106. Thus coefficient of thermal conduction lambdaH between the hot wire 1 and the holder 15 becomes approximately equal to coefficient of thermal conduction lambdaC between the cold wire 2 and the holder 15. Even though there is the difference in temperature between intake air and a body 107, the flow rate of the intake air passing in the bypass 106 can be accurately measured.

IPC: G11B7/004
Filed: 1985-09-11
Abstract: PURPOSE:To attain the detection of high reliability with a disk recording device by giving a position control to a detection signal that read a sector discriminat ing signal applied to a specific area on a disk via an exclusive head with the discriminating signal supplied at every sector. CONSTITUTION:A counter 102 counts clocks 70 and delivers a pulse 420 with a pulse 310 defined as a start point. While a counter 107 counts clocks 70 and delivers a pulse 410 with a pulse 400 defined as a start point. The start and stop of these counting actions are controlled by an FF 100 and 105 respectively. Then a counter circuit 108 is cleared by a pulse 400 and counts clocks 70 and the contents of the circuit 108 are loaded to a register in the counter 107 when a pulse 300 is produced. Then the counter 107 starts its counting action at the pulse 400 and produces the pulse 410 when the count value of the counter 107 is equal to the contents of the register. In case the pulse 420 is not detected through gates 104 and 109 in a normal detection mode, the pulse 410 is produced. Thus the pulse 410 or 420 is delivered to an output pulse 430.

Inventor: KINOSHITA MASAHIRO
IPC: H02G1/16
Filed: 1992-07-06
Abstract: PURPOSE:To make it possible to repair a cable without cutting and rejoining it by cutting off a required range of a metal sheath including a damaged portion, covering the cut area with a cylindrical copper plate having a fault current capacity equal to or above that of the metal sheath, and joining both ends of the copper plate to the metal sheath over the entire circumference by soldering. CONSTITUTION:If a corrugated aluminum sheath 2 is damaged after the installation of a cable, a required length of the aluminum sheath 2 including the damaged portion is cut off to expose a plastic insulated power cable core 1. After it has been confirmed that there is no damage to the plastic insulator, lead is put by a plumber on the circumference of the aluminum sheath 2 in proximity to the cut area; thus a lead layer 3 is formed there and the circumferential surface is smoothed. A copper plate 4 having a fault current capacity equal to or above that of the aluminum sheath 2 is rounded into a cylindrical shape, and the cut area is covered with the resultant cylinder. Both ends of the copper plate 4 are joined to the lead layer 3 over the entire circumference using solder 5; the seam of the copper plate 4 is also joined together over the entire length using solder 6.

Title: Glass composition
Inventor: OSADA HIDEKI
IPC: C03C3/085
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To improve the specific Young's modulus of glass and also to increase the productivity of a glass substrate by specifying composition ratios of SiO2, Al2O3, MgO and ZrO2 being main components. SOLUTION: The composition range of main components are kept in 47.5-58% SiO2, 10-30% Al2O3, 10-30% MgO and 0.1-2.8% ZrO2 by weight ratio. When SiO2 is less than 47.5%, melt property becomes worse, and when SiO2 is more than 58%, crystal is hardly precipitated. Then Al2O3 is less than 10%, a precipitated crystal is small and strength is low, and when Al2O3 is more than 30%, melt temp. becomes high and the glass is liable to devitrify. When MgO is less than 10%, the chemical durability of a glass matrix phase is not improved, and when MgO is more than 30%, other crystalline phase is precipitated and desired strength is difficult to obtain. When ZrO2 is less than 0.1%, sufficient crystalline nucleus is hardly formed and fine and homogeneous crystalline structure is not obtained.  Also when ZrO2 is more than 2.8%, melt temp. becomes high and also the glass is liable to devitrify and melt formation becomes difficult.

Title: Voltage stabilization circuit
Inventor: OTSUBO TAKAYUKI
IPC: H02M3/338
Filed: 1990-07-26
Abstract: PURPOSE:To obtain stable output voltage by making a feedback circuit including a shunt regulator. CONSTITUTION:A shunt regulator 13 composing a feed-back circuit 9 controls an anode-cathode current with the voltage at a reference voltage input terminal 14. That is, when the induction voltage of the secondary coil 4 of a switching transistor 3 increases, voltage divided by voltage division resistors 7 and 8 increases, the anode-cathode current of the shunt regulator 13 increases, and potential at point (a) lowers. As a result, the turn-on time of the switching transistor 3 shortens and the induction voltage of the secondary coil 4 decreases. When decreasing, the induction voltage of the secondary coil 4 can be controlled so as to be constant by reverse action. Thereby stable output voltage can be obtained.
