Abstract: PURPOSE:To form a pn junction at low temperature, inhibit a drop in film quality and form a pn junction having high carrier concentration and shallow graded structure. CONSTITUTION:A non-doped (for example, n<-> type alpha-Si) an opposite conductivity type amorphous silicon layer (for example, n<+> type alpha-Si layer) are deposited on a substrate whose surface comprises at least one conductivity type crystal silicon layer (for example, p-type polycrystalline silicon layer) based on a CVD process at a temperature ranging from around 150 to 300 deg.C. Then, it is heat- treated and crystallized, thereby forming a pn junction having a graded structure. The carrier concentration of the crystallized silicon layer is in the order of 10<21>cm<-3> while the film thickness can be 200 to 2000Angstrom  (therefore, the thickness of the pn junction has the same depth). Moreover, it is possible to enhance short circuit optical current due to surface field effect by providing a graded structure. This pn junction has a sufficiently practical capacity to use as a solar cell.

Filed: 1988-01-21
Abstract: PURPOSE:To obtain driving torque suited for an adhesive condition even during a slip by making an armature chopper control its constant conduction ratio and a field chopper control its constant field current or fixed conduction ratio, while slip is generated. CONSTITUTION:When conduction ratio gammaa of an armature chopper is smaller than its conduction ratio instruction gamma', a comparator circuit 7 obtains its output L. Under this condition, when a slip is generated and a comparator circuit 22 obtains its output H, an AND circuit 8 obtains its output H. In this way, a sample hold circuit 6 holds the conduction ratio gammaa of the armature chopper in that time. A field chopper is so controlled that in its field current coincides with a field pattern. On the contrary, when the slip is generated with the conduction ratio gammaa larger than the conduction ratio instruction gamma', the armature chopper is controlled as it is, and the field chopper holds the prevailing conduction ratio.

Filed: 1989-01-19
Abstract: PURPOSE:To make it possible to suppress the increase of pH of electrolyte during the charging process by stopping the circulation of electrolyte in the positive electrode side for a specified time during the charging process. CONSTITUTION:During the charging process, positive electrode electrolyte in a storage tank 22 in the positive electrode side and negative electrode electrolyte in a storage tank 24 in the negative electrode side are both circulated. When the circulation of positive electrode electrolyte is stopped for a specified time during the charging process, the number of bromine ions Br<-> in a reaction tank 14 in the positive electrode side becomes deficient, and by the associated specific reaction the concentration of hydrogen ions in the electrolyte is increased to reduce pH. In order to adjust the reduction rate of pH the stopping duration of the circulation of the positive electrode electrolyte is controlled. Thereby the pH adjustment of the electrolyte can be carried out by simply turning ON and OFF of an existing pump 30 with no need to provide new means or to add chemical agent.

Title: Apparatus for and method of measuring hardness of thermosetting resin material for molding
Inventor: TSUZUKI SUSUMU
IPC: B29L31/34
Filed: 1980-02-04
Abstract: PURPOSE:To evaluate the hardness of a resin in a die gate accurately by determining whether a pressure transmits to a cavity through the resin after it is retained in the gate for fixed time. CONSTITUTION:An upper die 5 and a lower die 6 are closed to throw a resin into an opening 7. Then, as a hydraulic device 3 is driven to lower a plunger 4, the resin is forced into a cavity 10 through a gate 9. When the resin pressure in the cavity reaches P1, the action of the hydraulic device stops, where the resin pressure becomes zero. After the time elapses by Xt, the hydraulic device 3 restarts to lower the plunger to increase the resin until it shows the highest value P2 by a pressure indication comparator 14. As the time Xt is prolonged, the resin in the gate 9 comes to be hardened where the resin pressure fails to rise again. The value Xt is varied by stages and the value P2 is read out at each time. Even if the time Xt is further extended, the value P2 can remain high. In this case, it should be determined that the resin is hard to be hardened in the gate 9, that is, poor appearance is hard to take place in the molded product.

Abstract: PURPOSE:To change the hue in response to the preference of the user by provid ing a phase shift means shifting a chrominance carrier signal by an angle in response to a command at each other horizontal scanning period and demodulating a chrominance difference components included in the output of the phase shift means. CONSTITUTION:The output of the amplifier 5 of the phase shift circuit 15 is fed to a phase shifter 16 and inputted to a changeover switch 17. A control signal having a level in response to the operating state of a hue adjusting operation button at the operating section is fed to a control input terminal of the phase shifter 16 and the phase shifter 16 delays the phase of the input by an angle in response to the level of the control signal. Since the gain of the matrix circuit 14 is changed in response to the phase shift angle of the phase shifter 16, the combined vector length of two vectors corresponding respectively to B-Y and R-Y signals outputted from the matrix circuit 14 is made equal to a length D1. Thus, the combined vector of the two vectors is made identical to a vector formed by turning the combined vector D1 by an angle phi/2 and only the hue is changed without changing saturation.
