Title: Manufacture of thermal head
Inventor: SHIRAKAWA KYOJI
IPC: H01C17/06
Filed: 1985-06-27
Abstract: PURPOSE:To stabilize the quality of plating at a terminal part and thereby enhance yield of the product even where the film thickness of an Al conductor layer is small, by adding a heating treatment after Ni plating, in a conventional terminal plating process. CONSTITUTION:The Al layer in the region of a terminal part 10 is selectively dipped two times in a Zn substitution liquid, followed by electroless Ni plating to provide an Ni layer 7 in a thickness of about 2mum over the entire surface of the terminal. After drying the thus obtained material by Freon or the like, the material is heated in a belt furnace under one of the conditions of 150 deg.CX5min, 200 deg.CX1min, 250 deg.CX30sec and 300 deg.CX10sec. Thereafter, Sn is deposite so as to surround the Ni layer by electroplating, thereby producing the terminal part 10 for connection to an external circuit. With the heating under the above heating condition, adhesion is markedly enhanced, and excellent strength can be maintained.

Title: Controlling device for cooling and heating
Inventor: UENO JIYUNICHI
IPC: F24F11/02
Filed: 1980-10-03
Abstract: PURPOSE: To synchronize the whole system by a method wherein clock words containing the summer and winter informations are given at the fixed period to local controlling devices in the air-conditioning system consisting of a central controlling device and a plurality of the local controlling devices.  
     CONSTITUTION: The central controlling device MC transmits at the fixed period the clock words containing the summer and winter informations. The start of analog to digital conversion and the operating direction of operating end due to the summer and winter informations are provided by the clock words. Detected temperatures, which are converted from analog values to digital values by means of an analog to digital conversion starting signal ST, and stored in the local controlling device SC, as controlled variables. On the other hand, because the cooling operation and the heating operation necessitate the movements of the operating end, the directions of which are opposite each other, the directions are provided by the summer and winter informations. A time-proportional-position action is employed as a controlling action and a controlling operation is performed at the period of seconds on an electric heater which has no moving part and on the basis of mean values calculated at the period of minutes on cold and hot water valves and the like.

Title: Differential amplifier
Inventor: INOUE HIDEKAZU
IPC: H03F3/45
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To correct an offset automatically by providing a 1st differential amplifier amplifying an output signal of a correction circuit and a feedback circuit or the like that applies a base voltage of a 3rd transistor(TR) to the correction circuit as a control signal and obtaining the output signal from the 1st differential amplifier. SOLUTION: A signal from a TR 20 is fed to a 1st differential amplifier 24, in which the signal is amplified and led to an output terminal 27. In this case, an offset is corrected by feeding back an output signal to an input of the 1st differential amplifier 24 so as to make base voltages of TRs Q2 , Q7 match each other accurately, That is, a 2nd differential amplifier 25 having 1st and 2nd TRs Q3 , Q6 detects an offset voltage, it is converted into a current, further converted into a base current being a very small current by TRs Q4 , Q5 and filtered by a capacitor 26 with small capacitance. Thus, the current resulting from the offset voltage is filtered and fed back to the input of the 1st differential amplifier 24 amplifying an output signal of a correcting circuit in this way, then the offset is automatically corrected.

Title: Redundancy suppression coding system
Inventor: OCHI HIROSHI
IPC: H04B1/66
Filed: 1978-11-14
Abstract: PURPOSE: To suppress the redundancy of the picture including the intermediate gradation through a simple process by giving the run-length coding to the gradation level every time the gradation level has change of one gradation and furthermore setting and inserting the gradation change inverted code.  
     CONSTITUTION: The first picture element of each scan line is set to gradation level 0, and then the run-length codes of gradation levels 1, 2... are transferred in sequence. As gradation levels 0∼7 feature run-length 0, the code of run-length 0 is repeated 8 times. After this, the code of run-length 2 with gradation level 8, the code of run-length 0 with gradation level 9, the code of run-length 2 with gradation level 10 and so on are transferred in sequence. After transfer of the code of run- length 4 with gradation level 13, the gradation changes from increment to decrement. However, in this case, gradation level 13 does not proceed to level 14 but to level 12. At this instant, gradation change inverted code R is transmitted. The same procedure is given even in the case of the opposite change of the gradation. For the run-length code, the short code is allotted preferably to the one featuring a high emergence probability in order to decrease the transmission bit number as much as possible for every picture element.

Filed: 1984-07-06
Abstract: PURPOSE:To permit easy maintenance and supporting of load in an optional position by using neck bearings fitted to the shaft part of a rolling roll as members for supporting the rolling roll. CONSTITUTION:The rolling roll body 1 is drawn out in a lateral direction while the neck bearings 3 are held attached thereto in the case of removing the rolling roll from a housing. The bearing 3 has a circular outside diameter and the diameter smaller than the outside diameter of the body 1 and can be therefore easily and quickly drawn out without paying consideration for the position of the bearing 3. Since there is no need for considering the position for supporting the load during rolling in the stage of inserting the rolling roll into the line, the roll is easily and quickly insertable into the housing.

Title: Multi-port memory
Inventor: SHIRAISHI ATSUSHI
IPC: G06F15/16
Filed: 1988-06-07
Abstract: PURPOSE:To enable a memory itself to avoid its working defects caused at collision of write addresses by invalidating the write requests to some or all ports having coincidence of addresses and therefore preventing the writing collision to the same address. CONSTITUTION:An address coincidence detecting circuit 11 checks the coincidence of write addresses among ports. When the coincident addresses are detected, a warning signal generating circuit 12 gives the information to the outside of a memory by means of a warning signal Alarm to show the detection of the coincident addresses. At the same time, a write request invalidating circuit 13 stops the relevant writing action. These circuits 11-13 have the simple constitutions and can be set into a chip which contains a memory cell array 16. Thus it is not required to suppress the external writing actions to the same address via the software or the hardware. In addition, such problems like the circuit/wiring spaces, etc., can be eliminated.

Title: Ink jet head
Inventor: MIZUNO TSUNEO
IPC: B41J2/145
Filed: 1986-06-17
Abstract: PURPOSE:To lessen the variation of ink particle speed by making the mutual operation by the simultaneous drive of adjacent piezoelectric elements less, by a method wherein the tapered part in which the ink feed path side of a pressure chamber becomes narrower is provided and a part of a piezoelectric element is so established as to overlap with the tapered part. CONSTITUTION:A tapered part 120 is established in a tapered shape so that its width on the ink feed path 11c-11e side of pressure chamber 12c-12e becomes narrower. Then, a part of the piezoelectric element 20c-20e provided to the pressure chamber 12c-12e via a drive plate is so established as to overlap with the tapered part 120. Because the tapered part 120 is provided to the pressure chamber 12c-12e and a part of the piezoelectric element 20c-20e is so provided as to overlap therewith, the interval between the pressure chambers 12c-12e can be made equivalently large in the tapered part 120. Therefore, though the interval between the pressure chambers 12c-12e are made small, the influence of mutual action by the simultaneous drive of adjacent piezoelectric elements can be made less and the variation amount of ink particle speed to that in single drive time can be made less.
