Title: Current supplying method in electrolytic polish
Inventor: ISODA SHIGEO
IPC: B23H5/00
Filed: 1987-06-23
Abstract: PURPOSE: To provide constant values of voltage-current characteristics and avoid the generation of an abrasion by forming a feeder element of a material having hardness higher than a workpiece and contacting the workpiece with 50gW150g of a press force.  
     CONSTITUTION: An aluminum alloy disk-like workpiece 11 is pinched rotatably by a plurality of rotary drive resin rollers 10 and contacts rotatably an electrode (negative pole) tool 12 with about 1kg/cm 2  of press force. Electrolyte is supplied from the polished surface while about 3 volt of DC voltage is supplied from a feeder element 13 for electrolytic polishing. This feeder element 13 is formed of quenched steel having hardness higher than the workpiece 11, for example Hv 600 of hardness, 0.2μmRmax of surface roughness and 6g/cm 2  of spring constant and contacts the peripheral end edge of workpiece 11 with 50W150g, preferably 70W90g of press force by a feeder element support 14. Thus, voltage- current characteristics in the feeding spot will have constant stable values and so abrasions occur in carring out surface polishing.

Filed: 1991-06-28
Abstract: PURPOSE:To enable an easy retrieval with a simple and inexpensive constitution by automatically discriminating the presence of the information recording of a recording medium after specifying an automatic retrieving mode and executing retrieval or a reproducing operation without unnecessary reproduction. CONSTITUTION:When the automatic retrieving mode is specified by a command means 1, a controlling means 5 run a recording medium 6 at a high speed by the driving means 2 and the recording signal of the medium 6 is read by a pick-up means 3. This signal is transformed into a signal which shows the presence of information recording by a detecting means 4 and when a non-signal condition within a maximum period is detected, a forward direction retrieval is operated by the means 5 and the starting point of the information recording is retrieved. When the non-signal condition within a maximum period is detected by the means 4, a reverse direction retrieval is operated by the medium 6 and the starting point of the information recording is retrieved. When the starting point is detected by the forward direction retrieval, the information recording is reproduced by a user command during reproduction, an operation is returned to the reverse direction retrieval for detecting a non-signal condition over a maximum period. Thus, the constitution is simplified and the retrieval is made easy even if there is a damage on the medium 6 locally.

Title: Low frequency amplifier of battery driven electronic device
Inventor: TANAKA SHIYUNICHI
IPC: H03F3/68
Filed: 1982-09-14
Abstract: PURPOSE:To obtain a miniature amplifier of high quality with a low cost, by connecting a load between a joint of a pair of output transistors (TR) connected in series to each other and the end of a battery power supply and therefore driving the load without using a transformer despite a low level of power supply voltage. CONSTITUTION:When the signal reception is carried out, a control terminal 60 is grounded to supply power supply voltage 104 to OTL amplifying circuits 28A and 28B. An input signal 100 is supplied to output TRs 38A and 40A via TRs 32A, 34A and 36A. The TR38A is equal to a pnpTR, and the voltage which varies in the rising direction from the bias voltage is applied to the base of the TR38. Thus the voltage is reduced between the collector and the emitter, and therefore the npnTR40A performs an adverse amplifying action to carry out a push-pull operation. The voltages of same phases are supplied to the TRs 38A and 40A, and the intermediate potential between the TRs 38A and 40A is set at 1/2 voltage 104 by a resistance 66A. Thus a sine wave signal 102A based on 1/2Vcc is obtained when the signal 100 has a sine wave. The signal 102A is also supplied to the circuit 28B. The levels are matched with each other between output signals 102A and 102B by a resistance 58. Then the output signals having opposite phases and the same voltage are applied to a speaker 16.
