Inventor: SUNAHARA KAZUO
IPC: C04B41/88
Filed: 1989-02-22
Abstract: PURPOSE:To obtain the fine adhesion with a ceramics substrate including Pb by using the paste made of the composition including the predetermined quantity of Ag powder, Pd powder, crystallized glass frit, glass frit and Nb2O5+ TaO5+TiO2+ZrO2. CONSTITUTION:The paste is made of Ag powder 45-95, Pd powder 2-45, 60<=Ag+Pd<=97, crystallized glass frit 1-40, glass frit 0-39, glass frit total <=40, Nb2O5+TaO5+TiO2+ZrO2 with 0.1-10 of the composition (wt.%). When the paste is coated on a green sheet or a ceramics substrate including Pb and is baked, the metal oxide react with Pb in the ceramics substrate to bond strongly, and a quantity to be grazed is a little and the solder-wettability is good because of the crystallized glass. In the case of a multiple layer substrate, the desirable composition is 78<=Ag(80-99)+Pd(0-20)<=99, crystallized glass frit (0.1-20) + glass frit (0-19.9)<=20Nb2O5+TaO5+TiO2+ZrO2<=0.01-10.

Title: Film winding and rewinding circuit of camera
Inventor: TABATA YASUSHI
IPC: G03B17/00
Filed: 1984-03-05
Abstract: PURPOSE:To inhibit a motor from rotating in a film rewinding direction unless the sprocket of a camera side is released and disallow the rewinding operation of a film. CONSTITUTION:When the film is rewound after photography, winding/rewinding selection switches SW1 and SW2 are operated so that terminals SW1a and SW 2a connect with common electrodes SW1c and SW2c. Then, a switch SW3 for flow passage switching also has the common electrode SW3c connected to the terminal SW3a associatively. Then, when the sprocket which engages perforations of the film is released, a rewinding switch 64 is turned on. Consequently, a current flows to the coil 18 of a relay 14 through the switch SW3 and rewinding switch 64 and the common electrode 16-1 of the switch 16 is connected to the terminal 16-3. Then, a current flows through a motor 10 from the selection switch SW2 to the selection switch SW1. This current direction is opposite to that in winding operation and the film is therefore rewound.

Title: Range finder
Inventor: ODA YASUO
IPC: G01B11/02
Filed: 1980-03-28
Abstract: PURPOSE:To improve the steel piece yield, by operating the average distance from a prescribed position in the photoelectric element side to the object to be measured by the timing signal related to beam scanning and by specifying the position of the surface having ruggedness to show its actual state. CONSTITUTION:Rotary mirror 6 is rotated in one direction in a constant speed, and the laser beam irradiated from laser beam generating device 8 to rotary mirror 6 is scanned vertically on one side face of steel piece SP and is reflected there. Consequently, the region on steel piece SP to which the detecting part consisting of object lens 1, light shield plate 2, condenser lens 3, and photoelectric element 4 is just opposite is irradiated periodically by the laser beam. Since light shield plate 2 is interposed in the light path of the detecting part, photoelectric element 4 receives intermittently the reflection light of the laser beam due to the surface of steel piece SP. In this intermittent light receiving, the position on the surface of steel piece SP irradiated by the laser beam is determined by the slit position of light shield plate 2. The signal detected by photoelectric element 4 is input to the data processing part, which is not shown in the figure, to calculate a required distance.

Title: Modem circuit
Inventor: SUGA YUKIO
IPC: H03C1/54
Filed: 1979-04-06
Abstract: PURPOSE:To prevent a carrier noise from being generated by providing a level shifting circuit between a DC amplifying circuit and multiplying circuit and then by inserting a capacitor into the gain control circuit of the multiplying circuit. CONSTITUTION:From terminals T1 and T2, signals to be modulated and demodulated are input and from terminals T13 and T14, earrier signals are supplied. Then, the modulated and demodulated signals are shifted by level shifting circuit 3 by way of DC amplifying circuit 1 and then input to transistor TRQ1 and Q2 of the multiplying circuit. Currents flowing through TRQ1 and Q2 are made unrelated mutually in terms of DC by capacitor C5 inserted into the gain control circuit and limited to constant values by TRQ7 and Q8. As a result, the gain of the DC component is zero and even if amplifying circuit 1 would generate an offset voltage, no modulated signals is output from terminals T11 and T12. Therefore, a carrier noise can be prevented from being generated.

Among that, 50-80% is added to the compound as the ternary alloy powder of 60-70%-Ni-15-35%-Cu-5-15% Mo and the balance is added as 20-50% Ni powder simple body. The additive rate of the C powder is furthermore regulated to 0.5-1.0%. Said mixed body is sintered in a nonoxidative atmosphere contg. a vacuum at 1,150-1,250 deg.C and thereafter is cooled at the cooling rate of 10-30 deg.C/min from the sintering temp. to room temp. The sintered body is then subjected to the subzero treatment at <=-20 deg.C, and after that, is applied to the heat treatment. The high strength sintered member having high dimensional precision is thereby obtd. by the relatively low temp. sintering without requiring a quenching process.

Once a write command signal is inputted from control part 6 to AND circuit 9 via bus 24, the output of circuit 9 controls writing in memory part 12 via bus 29 according to the state of element 10. However, when element 10 is in set mode, circuit 9 sends its output via bus 29 by the output to suppress writing in memory part 12, thereby preventing malfunction.

A second pickup 3 (second PU) is moved from the readout requirement position of the first PU to the readout completion position of one reproduction unit and starts the reading of a second reproduction unit after it completes its movement. In the midway in which the second PU reads data, the first PU completes the reading of the first reproduction unit to store them in a buffer memory 17 and it is moved again to the readout completion position of the second PU and starts the reading of the third reproduction unit after it completes its movement. Thus, the device becomes reactable to the data requirement of a host computer 14 at high speed by repeating these operations.
