Title: Apparatus and method for band-gap voltage reference
Inventor: BAOSON NIYUIAN
IPC: G05F3/30
Filed: 1994-04-21
Abstract: PURPOSE: To obtain a stable and exact band gap voltage reference without any temperature dependency. CONSTITUTION: The band gap reference circuit (14) generates a band gap voltage reference (VBG) at the bases of transistors Q1 and Q2 . A reference current signal (IT) is generated by the difference of base/emitter voltages due to the difference of emitter areas between the transistors Q1 and Q2 , and allowed to flow to the collectors of the transistors Q1 and Q2 . A corrected current signal (ITT) generated by a current squaring circuit (16) is poured into the collection of the transistor Q1 so that the collectors of the transistors Q1 and Q2 can have unequal current values. The current squaring circuit (16) squares the reference current signal (IT), and divides it by a sampling current signal (ISC) generated at a current generator/amplifier in order to generate the corrected current signal (ITT).

Title: Wire dot printing head
Inventor: IWAMI HIDEAKI
IPC: B41J2/235
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To prevent the printing characteristic change even with a filler expanded by providing a means for absorbing the expansion of the filler in the lateral direction in the vicinity of a coil which releases a swingably-supported armature having a printing wire fixed at the tip by selective excitation. SOLUTION: A wire dot printing head has a filler 36 made of a silicone resin filled in a wire dot printing head for transmitting the heat of a coil 32 to a sheet sinking cap for heat radiation 24 as well as a coil bobbin 31, the coil 32, and a core 33, fixed to a base 20. Ring-like air layers 40A, 40B are formed as an expansion absorbing means at the inside and the outside of the core 33 with respect to the radial direction of the filler 36, respectively. Accordingly, even when the filler 36 expands in the lateral direction, since the air layers 40A, 40B absorb the expansion, an uneven pressure is not applied to the core 33 so that the suction point of the armature 34 is not dislocated.

Abstract: PURPOSE:To obtain a compact optical system and furthermore to accurately detect a focus and a track by using a combination lens system consisting of convex and concave lenses. CONSTITUTION:The light beam made incident on a convex lens 12 attached to the light incident surface of a half prism 14 and focused light beam is separated into two beams by the prism 14. One of these two beams passes through the prism 14 as a focus detecting light beam and is made incident on a concave lens 16 and then on a focusing detector 20 via a cylindrical lens 18 after dispersion. Meanwhile the other beam is reflected by a half mirror of the prism 14 and made incident on a tracking light detector 22 as a tracking guide detecting light beam. In this case, a tracking detecting optical system consists of a convex lens having a large refractive index and therefore the total length of this optical system can be reduced. Thus a compact optical system is obtained.

Title: Semiconductor storage device
Inventor: MUROYA YUKINORI
IPC: G11C16/06
Filed: 1990-03-30
Abstract: PURPOSE:To attain a high speed operation by providing an interruption circuit interrupting a signal inputted to a latch circuit in accordance with an equalizing pulse signal while an equalizing circuit equalizes the input-side of the latch circuit. CONSTITUTION:The latch circuits 13 and 14 are connected to the output ends of differential amplifiers 36a and 36b through clocked (CMOS) invertor circuits 11 and 12. The latch circuits 13 and 14 latch a signal which the differential amplifiers 36a and 36b discriminate. Consequently, the signal is not transmitted by the clocked invertor circuits 11 and 12 in an equalizing period, and signals before the generation of the equalizing signal which the latch circuits 13 and 14 latch are outputted as Q and the inverse of Q. Thus, the signal of a prescribed level can securely be outputted.

Abstract: PURPOSE:To safely use a gas cooker even if the pressure of gas in the cylinder extraodinarily rises, by bringing a nozzle of check valve into the closed condition by pushing up a check valve by high pressure and by deforming a belleville spring. CONSTITUTION:When a gas cylinder 1 is assembled in the body of gas cooker, a valve stem 17 pushes to open a check valve 3, of which valve nozzle 2 is the closed condition. This time, as the check valve 3 itself is moved by a coil spring 6 contracting, the rear end 3' of the valve is contacted to the belleville spring 7, and a part of force to open a valve of gas cylinder acts to the check valve 3 by the belleville spring 7. If the pressure of gas in the gas cylinder extraodinarily rises by some reason, the check valve 3 is pushed up by high pressure and the belleville spring 7 is deformed. The valve nozzle 2 is brought into the closed condition by the action of a spring 19, therefore, the gas heater can be used safely.

Abstract: PURPOSE:To make irradiation power density constant, by correcting the change of gas concentration in an exposure chamber, the change with time of current value of an electron storage ring, the change of reflection factor due to the oblique incident angle of synchrotron radiation light (SOR light) in a swing mirror, and the fluctuation caused by the change of beam spot size. CONSTITUTION:When an X-ray shutter 8a is opened, synchrotron radiation light (SOR light) 1 is introduced into a beam line part 3 under an ultra-high vacuum. At the same time, a control signal SA is applied to a driver 9b of a swing driving part 9 from a central operating part 18. In the central operating part 18, the swing angular velocity to the swing angle theta of a swing mirror 8 is calculated in real time, and the control signal SA is so outputted that the swing mirror 8 is driven at the calculated swing angular velocity. As the result, the swing angular velocity omega of the swing mirror 8 is sequentially changed so as to correct the 'fluctuation' of exposure amount. Thereby the irradiation power density is made constant.
