Title: Hot water generating method employing multitube type heat exchanger
Inventor: FUKUI RYUJI
IPC: F24H1/18
Filed: 1987-02-10
Abstract: PURPOSE:To prevent the occurrence of a fluctuation in hot water temperature and water hammer due to a fluctuation in the amount of hot water used, by a method wherein condensate of steam is stored in the container of a multitube type heat exchanger, and by changing a condensate level according to an amount of hot water used, a hot water temperature is controlled. CONSTITUTION:When the mount of hot water 12 used is small, the temperature of the hot water 12 is increased, and a water level rise signal for condensate 9 is transmitted from a temperature regulator 2 to a water level regulator 7 so that the heat transfer surface of a heat transfer tube 5 is decreased. Through measurement of the present condensate 9 level, the opening of a water level regulating valve 8 is throttled according to a deviation between a water level to be set and the present value, and the condensate level is lowered to a value near a set value by reduction of a drainage amount of the condensate 9. When the amount of hot water 12 used is increased, the condensate level is lowered to a value near a set value by similar action described above. Cascade control, where a set hot water temperature is set as a target value, is effected, a fluctuation in a hot water temperature due to a fluctuation in the amount of hot water used is prevented from occurring, a conventional steam flow rate regulating valve is eliminated, and water hammer occurring due to opening and closing of a valve is prevented.

Inventor: MAREI JIEI ROBINSON
IPC: H01L27/06
Filed: 1992-02-14
Abstract: PURPOSE: To provide a new bipolar transistor structure wherein, for improved operation speed and reduced capacity, effective base width EBW is narrower. CONSTITUTION: As a feature, an emitter region E of a bipolar transistor structure 12 and a sub-emitter/collector region SEC which is positioned, while being localized under an active base region layer ABL are formed in an imbedded collector layer BCL. Into a sub-emitter/collector region SEC, N-type atoms which, distributed or diffused in retrograde concentration, diffuses at a relatively high speed are implanted from the embedded collector layer BCL into an epitaxial layer EPI, preferably, from an active base region layer ABL under the emitter region E to upward. Preferably, phosphorus atoms are implanted into the sub-emitter/collector region in relatively a high N<+> -concentration. The sub-emitter/collector region SEC occupies a horizontal-direction cross-sectional area, about 10-20% of horizontal-direction cross-sectional area of the imbedded collector layer.

IPC: G09G3/12
Filed: 1991-01-28
Abstract: PURPOSE:To realize a control circuit for the fluorescent display tube which can controls the filament circuit of the fluorescent display tube. CONSTITUTION:The voltage at the terminal 6b of the base circuit of a transistor(TR) 6 is held at 0V to turn on an FL 2. At this time, the TR 6 turns on and the center tap of the coil (m) of a transformer 3 is connected to the ground, so the bases of TRs 4 and 5 are held at a specific potential about the ground. In this state, if the voltage of the coil (m) is as shown in a figure, the TR 4 turns on, so a filament current flows to turn on the FL 2. When the voltage of the coil (m) is opposite, the TR 5 turns on.

Title: Belt screen type display image converter
Inventor: KONISHI TOSHIO
IPC: G09F19/18
Filed: 1987-02-12
Abstract: PURPOSE: To perform image continuous conversion economically and compactly by using a belt screen where only areas corresponding to display constitution characters or graphics are cut away and parts whose display are unnecessary are completely shielded from light. CONSTITUTION: Sections of optical fibers 3 are compactly bundled and fixed at uniform vertical and horizontal pitches like a single flat belt to form a light reception face, and a belt screen 1 moved in the vicinity of the light reception face is loaded. If the belt screen is made of a light shielding material, all of areas of display constitution characters and graphics are cut away; and when the belt screen is transparent, parts other than display constitution characters and graphics are completely shielded from light. Light of a monochromatic light source 7 is transmitted through the rotating belt screen 1 and a color filter drum 5 to continuously convert characters and graphics to vivid images on a display face 14.  Thus, characters and graphics are continuously converted to vivid, compact, and beautiful images like a flow because the light reception face is formed by closely bringing optical fibers into contact with one another in series and display parts on the screen are light-transmissive or cut away.

Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To realize a temporary down-shift for an engine brake only with one time down-shift requesting operation by a method wherein a down-shift means for use in shifting temporarily from the present gear stage to a gear stage lower than the former by one stage in response to a down-shift request operation is provided in an automatic transmission range selection. SOLUTION: During a D-range running operation, a shift lever is operated to change over it to an H range, a range map Mi corresponding to a gear stage (i) at that time is selected so as to perform an H range running operation. During an H range running, when a down-shift request operation is carried out, the map Mi of any one of (c) to (e) (if the present gear stage (i) is the fourth speed, for example, M4 range map) is stored. Then, in order to change over the range map to an Mi-1 range map of a gear stage (i-l) lower than the present gear stage (i) by one stage, the running state indicated by a point Pi is changed from (e) to a third-speed available region (d) and then it is possible to realize a down-shift transmission from the fourth-speed to the third-speed for the engine brake.

Abstract: PURPOSE:To minimize the deformation of a wall due to a rise in the inner pressure of a liquid chamber and to improve jetting efficiency by overlapping comb teeth of a vibrator by means of shifting them by every half pitch so as to form an ink channel, deforming the channel by the piezoelectric effect of the vibrator and jetting ink. CONSTITUTION:The piezoelectric vibrator 9 is bonded with a substrate A, on which grooves are made by a diamond saw. To produce a head of 8 grooves/mm, four grooves/mm are made on one side, for instance, a groove width of 90mum and a wall width of 160mum. Groove depth allows alpha (alpha is a cutting allowance of an electrode). To prevent ink from invading into the vibrator, an insulating film 7 is coated to insulate the electrode. Two substrates processed in such a way are prepared; one is turned the bottom up and both of them are joined at a wall overlapping part by shifting the difference by every half pitch. A nozzle plate 10 is bonded on the end of the substrates 3 and 8. The other end is obliquely cut to expose the electrode, and the substrates 3 and 8 are wired 12 by wire bonding or patterning to join with a driver 13.
