Title: Semiconductor device
Inventor: FUNATO AKIHIRO
IPC: H01L29/78
Filed: 1989-03-20
Abstract: PURPOSE:To obtain a highly accurate resistance value by providing a gate electrode at the upper part or the lower part of a resistor layer through an insulating film having a specified thickness, and changing the resistance value by a voltage applied on the gate electrode. CONSTITUTION:A gate electrode having a structure which crosses the partial region of a resistor layer 2 is provided on the N-diffused resistor layer 2 through an SiO2 film 5 having the thickness of 1,000Angstrom  or less. The resistance value of the resistor layer 2 can be changed by changing a gate voltage which is applied to said gate electrode 6. When the resistor comprising a P-diffused layer is formed on an N-type substrate, the same structure can be obtained. Since the dispersion in resistance value can be corrected after manufacturing, the highly accurate resistance value can be obtained readily.

Title: Casting method for wrapping metal
Inventor: MIKI ISAO
IPC: B22D17/00
Filed: 1978-06-05
Abstract: PURPOSE:To easily manufacture the excellently cohesive parts wrapped in the cast metal applying a low pressure, by previously forming the coating layer of a specified metal on the surface of the copper pipe, when the copper pipe is to be wrapped in the cast aluminum by the die casting method. CONSTITUTION:At manufacturing the heat exchanger, etc., the copper pipe 2 is wrapped in the cast aluminum 1 so as to form a one body. In this case, the coating layer 3 of zinc, zine-alloy, tin-alloy, etc., is previously plated on the surface of the copper pipe 2. This plated copper pipe 2 is wrapped in the molten aluminum 1 being cast under a comparatively low casting pressure of 100-200kg/cm<2> by the die casting method. Since the casting pressure is low, the copper pipe 2 never causes deformation due to the pressure; besides, a part of the plated layer 3 is molten into the molten aluminum and forms an alloy; hereby, the copper pipe 2 strongly coheres with the wrapping metal, aluminum. On the other hand, the thermal conductivity of the boundary between the copper pipe 2 and the wrapping metal 3 shows no deterioration.

A part of the beam is reflected by the half mirror 9 to provide the light beam (light beam for synchronization) 5A for detecting the position of the light beam for scanning. The light beam 5a for synchronization enters the grid 2 and enters a photodetecting element 3 via a condenser bar 12. Since the non-transparent parts 2b are provided at irregular intervals to the grid 2, the sum of the change in the quantities of both the light reflected by the front face of the half mirror 9 and the light reflected by the rear face thereof is detected by the photodetecting element 3. The device is so constituted that the change in the quantities of said light has specified regular periods. The disturbance in the synchronizing signal is, therefore, eliminated and the exact light beam scanning is possible.

Title: Hot and cold water combination device
Inventor: NAGAOKA YUKIO
IPC: F16K31/06
Filed: 1989-03-17
Abstract: PURPOSE:To obtain a miniature combination device compounded of respective functions of a pressure governing valve and a temperature governing valve by balancing respective outlet pressure of a hot-water side valve body and a water side valve body, and while adjusting the mixture ratio with the attracting force and the resiliency of a variable magnetic force generating means and the magnetic material and the spring force. CONSTITUTION:When the current in the positive direction is flowed from a control circuit 18 to a coil 12, an iron core 20 generates the electro-magnetic force to resist to a magnetic material 22 mutually and energize a valve shaft 8 to the lower direction. Therefore, a water side is closed and a hot-water side is opened, and the outlet pressure pH 2 and PC 2 of a hot-water side valve body 4 and a water-side valve body 6 are changed to balance an automatic pressure governing valve 3. As a result, the temperature of the mixed hot-water rises. When the current in the negative direction is flowed to the coil 21, the iron core 20 attracts the magnetic material 22 and move the valve stem 8 to the upper direction to open the water side and close the hot-water side, resisting to the force of a spring 25. As a result, the temperature of the mixed hot-water lowers. A balance point of the automatic pressure governing valve 3 can be moved by changing the current to be flowed to the coil 21, and the mixed temperature is detected by a thermister 15 and computed by the circuit 18 to control the current to the coil 21.
