Patent JP-H02210861-A (JP)
Title: Semiconductor device and its circuit
Inventor: SAKAMOTO MITSUZO
IPC: H01L21/761
Filed: 1989-02-10
Abstract: PURPOSE:To contrive to hardly turn a parasitic N-P-N transistor into an ON- state by a method wherein the main part of an N-type semiconductor substrate region, which is used as the collector region of the parasitic N-P-N transistor, is removed by etching from the rear of a wafer. CONSTITUTION:A P-type semiconductor layer for element isolation use is provided on an N-type semiconductor substrate 1 and an N-type semiconductor element formation region is provided thereon. Moreover, an insulating layer 12 on the side of the rear of a P-type epitaxial layer region 3 to be used for element formation is selectively removed and the high-concentration N-type semiconductor substrate 1 is removed by etching using the layer 12 as a mask to contrive to expose the region 3 on the rear of a wafer. Accordingly, even if it is generated that the epitaxial layer 3 is forward-biased up, most of the high-concentration N-type semiconductor substrate region 1 under the layer 3 is removed. Thereby, a parasitic N-P-N transistor, which uses the substrate 1 as its collector, does not work.

Title: Controller for electric sewing machine
Inventor: IKISU NOBUFUMI
IPC: H02P29/00
Filed: 1979-03-16
Abstract: PURPOSE:To make the pitch of backstitching constant, by supplying an intermittent signal to energize a solenoid for a cloth feed reversing mechanism and applying a continuous signal for a period corresponding to the last stitch. CONSTITUTION:The output of a tachometer generator TG is applied to a speed control circuit SPC to generate a clutch coil signal CLS or a brake coil signal BRS. The output of the tachometer generator is controlled by a foot-pressed switch FSW. The output signal of the lower position detector DD of a position detecting unit PS for sewing-machine needle is applied to a reversal control circuit BTC to produce a signal BTS for energizing a solenoid for a cloth feed reversing mechanism. The signal BTS is made intermittent to reduce power consumption. When the solenoid is deenergized, the signal BTS is made continuous for a period corresponding to a final stitch. According to this constitution, timing can be arranged. As a result, the pitch of backstitching can be made constant.

Title: Display attribute setting system for graphic
Inventor: TANOBE EIKO
IPC: G06F3/153
Filed: 1989-02-09
Abstract: PURPOSE:To simplify the setting operation of attribute information by selecting a graphic having a desired attribute from in a graphic display already, selecting this graphic and setting the attribute information of a graphic generated newly. CONSTITUTION:First of all, a graphic having the same attribute as that of a graphic to be drawn from now on is sought on a display screen, and this graphic is designated. As a result, in the inside of a system, based on coordinate information of a designated graphic as a clue, attribute information possessed by its graphic is extracted, and its extracted attribute information is set as attribute information of a graphic to be drawn from now on. Thereafter, by executing an additional generating operation of the graphic in the same way as before, a new graphic is displayed on the display screen by an attribute corresponding to an attribute corresponding to the set attribute information. In such a manner, a graphic having a desired attribute is selected from in the graphic displayed already, and by selecting this graphic, the attribute information of a graphic generated newly is set. Therefore, the setting operation of the attribute information becomes extremely simple.

Title: Hydrogen fluoride gas analyzer
Inventor: FUJIMORI HARUO
IPC: G01N29/00
Filed: 1984-02-22
Abstract: PURPOSE:To analyze the concn. of HF in UF6-gas with good accuracy, by separating probe laser beam into analytical beam and reference beam and allowing only the analytical beam to pass the hot lens region of excited HF while detecting refractive spectral diffractions of both beams. CONSTITUTION:A gaseous mixture of UF6 and HF is flowed to piping 12 from the direction shown by the arrow 16 while HF laser beam is transmitted from a transmitter 70 to excite HF-gas. Further, HeNe laser is transmitted from a probe laser transmitter 11 and separated into analytical beam 30 and reference beam 29 by a slitter 24 to be transmitted to the piping 12. The HF-molecule excited at this time is deexcited in a non-radiant manner to generate a hot lens region 6. In this case, the analytical beam 30 receives the fluctuation of the gaseous mixture and the effect of the hot lens region 6 and reaches a beam receiver 9A while refracted. Because the reference beam 29 is not passed through the hot lens region 6, it receives only the fluctuation of the gaseous mixture to reach a beam receiver 9B. Therefore, by setting off gas fluctuations by detecting the refractive spectral diffractions of the beam receivers 9A, 9B, HF in the UF6-gas can be analyzed with good accuracy.

Title: Space-heating apparatus
Inventor: MURABAYASHI SHIGERU
IPC: F24S90/00
Filed: 1982-02-28
Abstract: PURPOSE:To prevent generation of heat-insulating air layers due to change in the volume of a latent-heat accumulating medium and to thereby improve the heat radiating characteristics of a space-heating apparatus consisting of a container incorporating therein a latent-heat accumulating medium that reduces its volume when its phase is changed from solid to liquid, by employing such a mechanism that the bottom of the container is freely expansible. CONSTITUTION:An expansible band 6, for instance, in the form of a bellows is used at the bottom surface of an enclosed container 5 of polyethylene which incorporates therein a latent-heat accumulating medium 1 such as calcium chloride or sodium hydrogen phosphate. When the latent-heat accumulating medium 1 is converted into liquid phase by the heat of solar rays, the volume of the medium 1 is increased as shown in Fig. (a) of the drawing, and expansion of the medium 1 is absorbed through extension of the expansible band 6. On the other hand, when a negative pressure is produced in the container 5 as the phase of the medium 1 is changed from liquid to solid, the band 6 contracts and pushes the medium 1 upward in the container 5 as shown in Fig. (b). Therefore, it is enalbed to prevent generation of air layers in the container 5.
