Title: Printing head for dot printer
Inventor: ITO AKIHIRO
IPC: B41J2/235
Filed: 1992-11-12
Abstract: PURPOSE:To reduce an impact when an armature returns to a former position and to always stop the armature at an approximately constant former position irrespective of temperature increase. CONSTITUTION:A dot printer printing head 1 is provided with an armature 4 that is attracted by an electromagnetic drive means 5 for driving a printing wire 2 to a printing position and returned to a former position by a return spring 6 for driving the printing wire to a non-printing position and a cushioning member 8 for reducing an impact when the armature is returned to the former position. The cushioning member 8 is formed by overlapping a cushioning damper sheet 80 on a thickness correction plate 81 reducing in thickness in accordance with the thickness increase of the damper sheet caused by temperature increase. If the thickness of the damper sheet 80 is increased by temperature increase, the thickness of the thickness correction plate 81 substantially reduces to offset the increase of the thickness of the damper sheet. In this manner, the thickness of the cushioning member 8 can be always kept approximately constant irrespective of temperature increase.

Title: Semiconductor memory device
Inventor: MIYAZAKI KAZUTOMO
IPC: G11C16/06
Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor memory device in which an increase in the number of terminals can be suppressed to a required minimum and in which a redundant memory can be inspected nondestructively while an increase in the area of a chip is being suppressed by a method wherein an input terminal is owned jointly. SOLUTION: When a defective memory cell is detected in a normal memory 30, the address of the defective memory cell is registered on a redundancy selection circuit 102. When a memory is accessed, the redundancy selection circuit 102 is set so as to be accessed to either the normal memory 30 or a redundant memory 20 according to the compared result of an input address with a registered address. According to a control signal RSEL, redundancy coersion selection circuit 101 selects and accesses a memory cell in the redundancy memory 20 according to the input address irrespective of the existence of the registered address. As a result, a redundancy memory cell can be inspected nondestructively.  When the input terminal of the addresses is owned jointly, an increase in the number of terminals can be suppressed, an increase in the area of a memory chip can be suppressed to a required minimum, and the cost of a semiconductor memory device can be reduced.

Abstract: PURPOSE:To perform stable operation by constituting an arm member of two members, respectively connecting a remote control cable to one end of the first member and a drive cable to one end of the second member, forming in both end parts of the first member a cam groove having an equal radius part and engaging one part of the second member with this cam groove. CONSTITUTION:When a shift control lever is handled, a member A of an arm 21 is turned through a remote control cable 11, thus a member B, engaged with a cam groove 23 of the member A, is turned in the same direction. Thus obtaining a stroke in a drive cable 12, a forward reverse switching mechanism is given force thus performing a required shift control. However, because equal radius parts 23a, 23b are provided in both end parts of the cam groove 23 in the member A, in the range where a roller 26 of the member B engages with these equal radius parts 23a, 23b, the member B obtains no movement, here a stroke of the cable 11 is not transmitted to the member B. Accordingly, in this range, no adjusting work is required till the stroke of the cable 11 is equalized to its play amount.

Abstract: PURPOSE:To accurately control the film forming velocity of a sputtering thin film by arranging an optical type film thickness gage in the vicinity of a base plate to be treated in a sputtering equipment and controlling the output of a sputter power source by the film thickness detection signal. CONSTITUTION:A sputter electrode 8 with a target 7 for sputter fixed thereon is provided oppositely to a holder 6 fitted with a base plate 5 to be treated in a vacuum chamber 1 for sputtering. An optical type film thickness gage 10 is arranged near to the holder 6 for the base plate. Since a sputter film sticks the monitor glass of the film thickness gage 10 similarly to the surface of the base plate 5 to be treated during sputtering work, light is allowed to collide against this sputter film and both the transmitted light and reflected light are monitored. The thickness and refractive index of the sputter film are detected by an electric signal. The detection signal is inputted to a film thickness controller 11 and compared with the set value in this controller 11. The film forming velocity of the sputtering film on the base plate 5 is properly controlled by controlling the power of a sputter power source 12 by this difference.

Title: Acoustic signal processing device
Inventor: SHUDO KATSUYUKI
IPC: G10L19/00
Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To allow slow motion reproduction of acoustic signals using as small capacity of memory. SOLUTION: Memory 5 is accessed in an annular condition that the maximum value and the minimum value are linked. When acoustic signals stored in the memory 5 are read out after being subjected to pitch conversion by means of time base compression and the write address value coincides with a specified one, the readout address value is changed to the address value close to an write address value. During the period in which the readout address value that so changed by the succeeding counting operations catches up with the write address value, an address founder 18 performs the counting operation of the readout address value.  Using this address counter 18 and a subtraction section 19 which outputs the address value different from the read out address value outputted from the counter 18 by a definite value, the address values respectively outputted from the readout address counter 18 and that outputted from the subtraction section 19 are used to gradually increase or decrease the signal levels read from the memory and to synthesize and output an acoustic signal.

Abstract: PURPOSE:To enable a short-wave laser ray source to be surely possessed of stable temperature control characteristics and to be lessened in output fluctuation by a method wherein heat released from a Peltier thermoelectric element is transferred to a part distant from a lens tube through a heat pipe and then dissipated. CONSTITUTION:One of the sides of a Peltier thermoelectric element 13 is brought into contact with the base of a case 12, and the other side is in contact with an aluminum block 14, so that heat released from the Peltier thermoelectric element 13 is transmitted to a heat pipe 15 via the aluminum block 14, transferred to a heat dissipating fin 16, and dissipated there to keep the case 12 constant in temperature. The case 12 and the heat dissipating fin 16 can be arranged separate from each other, so that the case 12 can be kept constant in temperature independent of the temperature of the heat dissipating fin 16, therefore a lens tube 10 fixed to the case 12 through the intermediary of a spacer 11 can be kept constant in temperature, and a semiconductor laser 1 can be kept constant in optical axis and output.
