Title: Picture recording and reproducing device
Inventor: TSUCHIDA TADAAKI
IPC: H04N5/765
Filed: 1990-04-24
Abstract: PURPOSE:To improve the utility by adopting the constitution such that the erasure is implemented by selecting the erasure mode able to select an optional recording area and the presence of recording is displayed. CONSTITUTION:The device is provided with each of picture signal recording, reproducing and erasure means and a mode changeover means selecting each function. At the changeover in the erasure mode, a recording area selection means selects a recording area of a recording element optionally and a display means displays whether a selected area is recorded or not recorded. Moreover, in the changeover state from the erasure to the pickup mode, an unrecording area selection means selects an unrecording area in the recording area. Through the constitution above, a photographer confirms the erasure. Moreover, a track to be immediately erased is moved in the case of rephotographing. An idle track is generated intentionally at the changeover to the pickup mode. Furthermore, an unrecording area selection means feeds an area till a succeeding unrecording area is obtained. Thus, the picture recording and reproducing device with remarkably excellent utility is obtained.

Title: Electric power amplifier
Inventor: TANAKA KOUICHI
IPC: H03F3/20
Filed: 1980-08-01
Abstract: PURPOSE:To reduce the loss of voltage as well as the variance of the idling current, by putting a series circuit of a transistor (TR) and resistance which are connected via a diode between the base and the emitter of the 1st and 2nd output TRs. CONSTITUTION:The relation between a current I'3 flowing to a diode chain 7 and a current I'4 flowing to TRQ12 and TRQ14 is shown by the equation (1), where S10-S14 show the emitter areas of TRs Q10-Q14. The relation between idling currents I'5 and I'4 when R3=0 is satisfied is shown by the equation (2), where S13 and S16 show the emitter areas of TRQ13 and TRQ16 respectively. The voltage drop due to a resistance R3 is set at 1.5mV when no signal exists, and thus the current I'5 is virtually decided by the emitter areas of the TRQ13 and TRQ16 and does not depend largely on the current amplification factor. When the level of an input signal is high, both the TRQ13 and TRQ15 can be completely driven by the resistance R3.

Title: Die for width rolling reduction press
Inventor: TAZOE NOBUHIRO
IPC: B21J1/04
Filed: 1987-04-30
Abstract: PURPOSE:To prevent the breakdown and wear of a die and the thermal effect onto instruments by executing uneven working on the die surface coming into contact with a slab. CONSTITUTION:A mesh like grooving 12 is executed in advance on the inclined part 10 and parallel part 11 on the surface of the press die 4 for width rolling reduction. Thus, the contact area of the die 4 surface and slab is remarkably contracted to reduce the heat conductivity between the slab and die 4 surface. The heat flowing amt. onto the die 4 is therefore reduced and the cooling effect of the die 4 is improved as well via the increase of the contact area. Moreover, the surface scale of the slab is crushed and removed with good efficiency due to the grooving. With the reduction in the heat flowing-in amt. from the slab and the improvement in cooling effect the temp. of the die 4 is reduced to prevent its breakdown and wear. Also, the thermal effect onto the peripheral instruments is prevented due to the temp. fall.

IPC: G06F3/03
Filed: 1991-05-13
Abstract: PURPOSE:To accurately know the period of replacement of an input part by driving an annunciating means when the frequency of depression of a depressed part of an input part exceeds a predetermined reference value. CONSTITUTION:It is judged whether or not a pen-down action is detected (step b1). Once the pen-down action is detected, an advance to a step b2 is made. When the pen-down action is not detected, coordinate detection at the input part is placed in a stand-by state. In the step b2, a counter in a CPU counts the number of times of the pen-down action. In a step b3, the counted value of the counter is compared with the predetermined reference value. When the counted value is less than the reference value, an advance to a step b4 is made to perform the coordinate detection by following up a procedure and in a stop b5, the detected coordinates are outputted to an output part. When the counted value is larger than the reference value, the operator is given an alarm urging the replacement of the input part in the step b6.

IPC: H03F3/30
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To secure the large amplitude of an output signal by setting the bias and signal levels of two output transistors TR independent of each other. SOLUTION: The DC component of the collector signal of a TR 16 is eliminated by a 1st capacitor 8, and only the AC component of the collector signal is applied to the base of a 1st TR 14. The DC level of the base of the TR 14 is decided by the ratio between the 1st and 2nd resistances 10 and 11 and the power voltage Vcc, and the AC level of the base of the TR 14 is decided by the capacity value of the capacitor 8 and the total value of both resistances 10 and 11. Thereby, the bias and the AC signal level of the base of the TR 14 can be freely set. The DC component of the collector signal of a TR 17 is eliminated by a 2nd capacitor 9, and only the AC component of the collector signal is applied to the base of a 2nd TR 15. Thus, the bias and the signal level of the base of the TR 15 can also be freely set.
