Title: Device in tappet valve system of internal-combustion engine
Inventor: OOHASHI RIYOUICHI
IPC: F02F1/42
Filed: 1983-08-03
Abstract: PURPOSE:To disuse a push rod, increase rigidity of a tappet valve system and achieve light-weight and compact design thereof by driving two intake valves which are disposed per one cylinder, by means of a cam via a bridge and an intake valve arm. CONSTITUTION:An intake cam 10 and an exhaust cam 11 are formed on a cam shaft 9 which is attached to a cylinder head 8. Intake and exhaust valve arms 3 and 5 are rocked by those cams 10 and 11, respectively. An exhaust valve 4 is directly opened and closed by the exhaust valve arm 5 while two intake valves 1A and 1B which are disposed per one cylinder are opened and closed by the intake valve arm 3 via a bridge 2. The exhaust valve is lower than the exhaust valve by the height l of the bridge 2. Since no push rod having low rigidity is applied in a tappet valve system, higher rigidity and light-weight and compact design thereof may be achieved.

Title: Printing device and printing method
Inventor: YAMAGUCHI KATSUYA
IPC: B41F33/14
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To provide a compact printing device which is capable of printing sheets with high print quality almost without a printing position deviation and at a reduced manufacturing cost as well as a printing method using this device. SOLUTION: The origin deflection level DX1, DY1, detected by edge sensors 42b-42d, of a printing sheet P to an image drawing region DA and the likewise detected inclination tanθ of the sheet P are sought. Further, image data in page memory corresponding to each of scan lines is read to adjust an address so that the deflection and the inclination are corrected. Consequently, no large- scale mechanism for correcting the positional deflection of the printing sheet P is required, so that the manufacturing cost of the device is saved. Thus it is possible to perform a high-quality printing almost free from a print position deflection.

Title: Masking method for lead wire connecting terminal
Inventor: ISHIKAWA SADAO
IPC: H01F27/29
Filed: 1978-11-18
Abstract: PURPOSE: To facilitate soldering and to enhance workability by masking a lead wire connecting terminal with polyamide resin layer before the terminal is impregnated with varnish.  
     CONSTITUTION: A thermoplastic polyamide resin with a softening point between 50W250°C is heated and melted. Into the molten resin immersed a lead wire connecting terminal which is later to be soldered, before the terminal is impregnated with varnish. Then, the terminal is pulled out of the resin and cooled to form a masking layer of the polyamide resin. This allows the soldering process to eliminates the need for removing varnish layer, thereby greatly enhancing working efficiency.

Title: Phosphate-type fuel cell power plant and exhaust heat recover method in phosphate-type fuel cell
Inventor: KOYAMA YOSHIO
IPC: H01M8/04
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To provide a phosphate-type fuel cell power plant of small size and low cost, in which heat and water can be recovered efficiently from exhaust gas. SOLUTION: Most of phosphorus oxide contained in exhaust gas is mixed with steam contained in gas by cooling in a partition type heat exchanger 20a upstream of an exhaust gas condensing heat exchanger 20, and then the resultant phosphate product adheres to the surface of a heating tube. Consequently, the phosphate product is rarely dissolved into a condensed recovery water to deteriorate a quality of water. In a direct contact type heat exchanger 20b positioned downstream, cooling water is brought into direct contact with the exhaust gas, so that high heat transferring/condensing characteristics can be achieved in comparison with the partition type heat exchanger, thereby miniaturizing the heat exchanger. Since it is unnecessary to use a heating tube or the like for a contact portion, providing an inexpensive exhaust gas condensing heat exchanger realized.

Title: Noise reducing circuit
Inventor: ITOGA MASAMI
IPC: H04N5/21
Filed: 1987-06-05
Abstract: PURPOSE:To always obtain a desired S/N and to suppress an after image phenomenon for various signals different in variable amount of an image by detecting a moving component average level from the inter-field difference signal of input video signals, and varying a coefficient value corresponding to an output signal from said detection. CONSTITUTION:A moving component average level detection circuit 11 measures a first average level of inter-field difference signals during one-H period in a vertical flyback cycle, and similarly measures a second average level of the difference signals during a vertical scanning period, then substracts the first average level from the second average level, and thus detects a moving component average level in every one-H period. A coefficient value setting circuit 12, when the detection circuit 11 decides that the inter-field variable amount per one-H period of video signals is large or small, outputs a signal in order to make the coefficient value K of a coefficient circuit 7 become smaller or larger. As a result, noise signals can be always suppressed even when video signals different in variable amount are impressed to an input terminal 1, furthermore, an afterimage also can be prevented.

Title: Image pickup device
Inventor: ADACHI YUKIHIRO
IPC: H04N9/04
Filed: 1987-06-09
Abstract: PURPOSE:To enable a manual correction of exposure by providing a means to control the operational characteristic of an AGC circuit based on a luminance information of an image pickup scope obtained from a color sensor. CONSTITUTION:An incident light beam 1 to the color sensor 10 is inputted to an interface circuit 11, and its 11 one output comes to a component of a color temperature information signal 15 and is inputted to a signal processing circuit 8, thus the original operation of full-auto white balance is executed. The other output from the circuit 11 is inputted to a selection circuit 12 as a luminance information signal 14, and is processed together with an AGC voltage 16 that is the output from the AGC circuit 7. A voltage controlled amplifier VCA 6 is controlled by an output 17 from the circuit 12, thus the maximum gain of the AGC circuit is increased/decreased. The operation of the AGC circuit varies corresponding to the magnitude of the amount of incident light beam; when the amount is large, the AGC circuit scarcely operates, hence the manual correction of iris is enabled. When the amount of incident beam is small, the manual iris correction is disabled.
