Title: Frequency-variable clock generation device
Inventor: DEEBUITSUDO ERU HAASHIYUBAAGAA
IPC: H04N5/91
Filed: 1992-04-25
Abstract: PURPOSE: To selectively generate a clock signal corresponding to any desired standard among plural digital video standards without switching plural oscillators to use. CONSTITUTION: In order to generate the output clock signals of frequencies respectively corresponding to the digital data rate of 1st and 2nd video standards, a voltage controlled oscillator(VCO) means 20 generates the clock signal of 1st or 2nd frequency corresponding to a 1st control signal. Corresponding to a 2nd control signal, a frequency dividing means 18 divides the frequency of clock signal from the VCO means with a 1st or 2nd coefficient. A video standard selecting means 15 generates the 1st and 2nd control signals so as to suitably combine these 1st and 2nd coefficients with the 1st and 2nd frequencies.

Title: Electronic balance
Inventor: MURAOKA TAKATOSHI
IPC: G01G23/48
Filed: 1986-06-06
Abstract: PURPOSE:To allow the display of load to naturally change without unnaturally fixing or abruptly changing the same, by converting load data and temp. data to digital signals by one A/D converter and stopping the taking-in of the temp. data only when load data varies. CONSTITUTION:The title balance is constituted of a balance part 1, a temp. sensor 2, an A/D converter 3, a change-over means 4 consisting of a gate circuit and a switching transistor etc. and a data processing part 5. When load data is stable, display does not change usually. At this time, a change-over order signal is outputted in predetermined timing and temp. data is intermittently taken in. When the load data varies, the change-over order signal is not transmitted to the change-over means even in predetermined timing and only the load data is taken in and displayed and, therefore, a display value varies continuously. As mentioned above, the display of load is changed extremely naturally while the load data and temp. data are alternately changed over by one A/D converter to perform data processing.

When the correct 8th digit number is depressed again, the number is set. Then the rest numbers are depressed successively and the end button is depressed finally, then all numbers are sent from a control section 2 and dialing is finished. Thus, the button information storage section 30 stores only one digit of button information and it is cleared by the information 202.

Title: Two-capstan driving type tape recorder
Inventor: NAKATANI YOUICHIROU
IPC: G11B15/43
Filed: 1983-07-21
Abstract: PURPOSE:To control the tape tension between two capstans of a take-up side capstan motor and a payoff side capstan motor to a specific value without providing any tape tension detector between the capstans by controlling the braking forces of electromagnetic brakes provided to the capstan motors so that the tape tension between the two capstans has the specific value. CONSTITUTION:When the tape tension between the capstans becomes larger than a value set by a tape tension controller 17, the output of an amplifier 16 decreases and the output of an amplifier 12a decreases. Consequently, the braking force of an electromagnetic brake 19 becomes small and the rotating speed of the payoff side capstan motor 5a becomes faster than that of the take-up side capstan motor 5b; and the amount of the tape unwound from the payoff side capstan 2a becomes larger than that of the take-up side capstan motor 5b, and consequently the tape tension between the capstands decreases to specific tension. On the other hand, when said tension becomes smaller than the set value, the output of the amplifier 12a increases and the output of the amplifier 12a also increases. Consequently, the braking force of the other electromagnetic brake 19 becomes larger on the contrary.

Abstract: PURPOSE:To form a thick insulating film for isolating an element in a narrow element isolation region with high precision by oxidizing an silicon layer in a region, a side surface of which is surrounded by an oxidation-resistant film, and controlling the thickness of the growth film of an silicon layer as the insulating film for isolating the element. CONSTITUTION:The ions of an impurity 18 for preventing inversion are implanted into an silicon substrate 11 in an element isolation region through a polycrystalline silicon film 13 and an silicon oxide film 12, using a photo-resist, an silicon nitride film 15 and an silicon oxide film 14 as masks. A polycrystalline (single crystal) silicon layer 19 is formed only onto the surface of the exposed polycrystalline film 13 in an opening 17 through a selective epitaxial growth method. The polycrystalline silicon layer 19, the polycrystalline silicon film 13 under the layer 19 and a section up to depth of approximately 250Angstrom  of the silicon substrate 11 under the film 13 are oxidized selectively, employing the silicon nitride film 15 as a mask for selective oxidation, thus shaping an element isolation silicon oxide film (an insulating film for isolating an element) 20. The previously ion-implanted impurity 18 is rediffused and activated at that time, thus forming an inversion preventive layer 21.

Abstract: PURPOSE:To realize a minimization of formation of a mixed layer within a hot water storing tank, an effective use of quantity of charged heat and maximization of quantity of hot water which can be used with respect to the capacity of the hot water storing tank. CONSTITUTION:Based on an output of a clock 9 which counts time after a start of operation, an output of a heating source 4 is controlled so that, at the start of the operation when low temperature water exist up to an upper part of the hot water storing tank 1, the temperature of hot water supplied out of an hot water outlet 3 is high, and on the other hand, when hot water has been accumulated and a mixed layer 1b of hot water and cool water has come downward, the temperature of the hot water is lowered down. Thus, by increasing a difference of density between the hot water from the hot water outlet and the water in the tank at the begining of operation, attenuation effect of flow velocity from the hot water outlet is increase while formation of the mixed layer is prevented as munch as possible. As a result, a ratio of hot water of a useless temperature becomes small, and therefore, the quantity of heated heat can be utilized effectively.
