Title: Valve lift mechanism for internal combustion engine
Inventor: AOYAMA SHIYUNICHI
IPC: F02D13/02
Filed: 1979-07-03
Abstract: PURPOSE: To vary the initial phase of a reciprocating cam held between a cam and a rocker arm in accordance with operation state, by respectively tapering contact face of the cam and the reciprocating cam in rotational directions each.  
     CONSTITUTION: A reciprocating cam 3 is turned about the axis of a rolling cam shaft 7 parallel with a cam shaft 2 and radially shaped like a wedge. The inclined face as of a tapered cam contacts with a rocker arm 5. For contacting with a first tapered cam 1, the back face 9 extending at an angle in the axial direction of the shaft 7 is applied with a load of a return spring 10 wound around the shaft 7. Thereby the reciprocating cam 3 is applied with a force by the return spring 10 in the clockwise direction, in other words, in a direction urging it against the first cam 1. A contact point of the rocker arm 5 on the cam face 8 varies as the cam 1 is lifted.

Title: Telephone terminal device for power line carrier
Inventor: KOBAYASHI KENJI
IPC: H04B3/04
Filed: 1980-06-20
Abstract: PURPOSE:To narrower the transmission band and to make effective use of the band, by controlling the level of the reception signal and the oscillation frequency of a voltage-controlled crystal oscillator through the reception linger signal. CONSTITUTION:A frequency shifting system linger signal including a control signal for measurement and data signal as well as a communication current voice current in a voice band is transmitted by a carrier suppression single side band system, and the linger signal is converted into a voltage corresponding to the difference from the reference frequency by a frequency discriminator 24. This voltage is compared with a reference voltage at a comparator circuit 25, and the output voltage of the circuit 25 is taken as a negative or positive reference voltage corresponding to the polarity to the reference voltage. The output voltage of the comparator 25 and that of the frequency discrimination circuit 24 are added via resistances R1, R2, and applied to a voltage-controlled crystal oscillator via a voltage amplifier 26 to control the oscillation frequency. The amplifier 26 produces a control voltage corresponding to the shift from the carrier frequency of the linger signal. As a result, a synchronizing pilot signal is made unnecessary.

IPC: F02M59/44
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To provide sliding parts for a fuel injection pump unit which consist of a reduced number of parts and have a performance capable of withstanding to long-term service under severe condition. SOLUTION: Sliding parts 1 for fuel injection pump unit have a body 1a formed by brazing a metal body 2 with a ceramic body 4 in such a manner that directions of center axes thereof are almost concided with each other. And end face of the ceramic body 4 opposite to an end face joined with the metal body 2 is a sliding face 4a of a driving portion of the fuel injection pump with respect to a cam. According to this construction in which the cam sliding faces of the parts are formed by the ceramic body 4, wear resistance is remarkably improved and parts life is extended compared with conventional sliding parts using metal roller. The parts are extremely simple in structure due to brazing the ceramic body 4 to the metal body 2 as the major portion of the parts.  The parts are exceedingly economical due to reduced use of the expensive ceramic constitution by using the ceramic body 4 only for a portion forming the sliding face 4a.

Abstract: PURPOSE:To form and change a ruled line with simple operation by storing plural patterns of the ruled line and changing and displaying the pattern of the ruled line every operation of a ruled line conversion key. CONSTITUTION:When the pattern of the ruled line is to be changed to another pattern after forming a table with ruled line marks by operating a carsor key and a ruled line mark key, a ruled line conversion/change key is depressed. Consequently, a key signal is outputted to a CPU through a keyboard control device KBC and an instruction group stored in an ROM is executed. A character code on a starting address of a refresh memory RM is read, and the character code is a ruled line code, the pattern is written in the original storing address of the memory RM by regarding the pattern as a thin ruled line. The rewritten code information is sent to a CRT control circuit CRTC, and while referring a character generator CG, the pattern is read out and displayed on a CRT. When the conversion key is depressed again, the information in the memory RM is converted into a thick ruled line code and displayed. When the conversion key is depressed once more again, a ruled wave line is displayed.

IPC: B23P6/04
Filed: 1989-04-04
Abstract: PURPOSE:To obtain a remelting part without imperfection productively at inexpensive cost by applying a magnetic field vertically to a surface to be treated which is remelted by arcs to stir a remelting part magnetically. CONSTITUTION:A torch 1 comprises a nozzle 3 in surroundings of a central electrode 2, and an exciting coil 5 is provided in its periphery. When arcs 7 are generated between the electrode 2 of the torch 1 and a casting 6 as a material to be treated, the surface of a part 6a to be treated of the casting 6 is melted by the heat of the arcs to form a remelting part 8. The current I flowing at this stage flows in parallel with a surface near the surface of the casting 6 and flows radially from the center of the remelting 8 as arrows in the figures show. When the exciting coil 5 is excited to give a magnetic field in vertical direction to the surface of the part 6a to be treated, Lorentz's force F is generated by an interaction of the current I described before and the magnetic field, and the melted metal is flowed in a certain direction to generate the stirring work. An internal imperfection is thereby floated and discharged, and a width of the remelting part is widened to improve productivity.

Title: Waste gas disposing euqipment for industrial furnace wherein raw material or accessory raw material is preheated by dry-type dust collector
Inventor: YAMAZAKI SHIGERU
IPC: B01D46/34
Filed: 1979-07-05
Abstract: PURPOSE: To remove the dust and efficiently raise the temperature of the accessory raw material or main raw material, by providing a dry-type packed-bed dust collector at the outlet port of a cooler of the waste gas disposing equipment and filling the accessory raw material or main raw material as a dust collecting layer in the collector.  
     CONSTITUTION: The dry-type packed-bed dust collector 3 is installed at the downstream side of the cooler 2. After the waste gas of a furnace 1 is cooled by the cooler, the gas passes through a dust collecting layer 15 made of the accessory raw material from a feeder 6 or main raw material from another feeder 7. At that time, dust in the waste gas adheres to the accessory raw material or main raw material and the temperature of the accessory raw material or main raw material is raised by the high-temperature gas of the cooler 2. Possessed heat is thus efficiently recovered without using a heat medium. The dust does not need to be separated. This results in heightening productivity.
