Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To improve operability, to reduce the occurrence of directivity and to facilitate exchange by providing an oscillation generation element, an oscillation transmission member and a pen tip member formed of a material having viscoelasticity for an input pen. SOLUTION: An oscillator 4 is driven by an oscillator driving circuit 2 and an electric driving signal is converted into a mechanical ultrasonic oscillation by the oscillator 4.

When the oscillation transmission member 5 is press-fitted to a rubber-formed pen tip chip 12, it easily deforms and both parts are integrally constituted with elasticity and they are closely adhered. Stable oscillation can be transmitted and inputted. At the time of exchanging the pen tip chip 12, rubber elasticity is used and it can easily be installed on the oscillation transmission member 5.  Directivity is improved by using NBR for the material of the pen tip chip 12, deformation by the direction of an oscillation input pen is eliminated and a coordinate can highly precisely be calculated in spite of the direction.

Title: Thermal head
Inventor: SHIRAKAWA KYOJI
IPC: B41J2/335
Filed: 1989-02-15
Abstract: PURPOSE:To enhance the thermal efficiency and the high-speed thermal response properties of a heat generating resistor by a construction wherein auxiliary current supplying conductor layers formed of a material with a low thermal conductivity is intermediately provided so that the widthwise interval thereof accords with a heat generating part of a heat generating resistor, and the widthwise spacing between a common current supplying conductor layer and a discrete current supplying conductor layer is set to be larger than the widthwise interval of the auxiliary current supplying conductor layers. CONSTITUTION:Auxiliary current supplying conductor layers 9 are formed of Ti, Zr or an alloy thereof which has a thermal conductivity of about 1/10 times that of Al used for common and discrete current supplying conductor layers 4a, 4b. Therefore, heat generated by passing an electric current to a heat generating resistor 3 is hardly transmitted to the conductor layers 4a, 4b. The widthwise spacing L between the current supplying conductor layers 4a and 4b is set to be greater than a heat generating part of a heat generating resistor 3, which construction increases the spacing between the contact part of the layer 4a and the resistor 3 and the contact part of the layer 4b and the resistor 3, so that it becomes more difficult for the heat of the resistor 3 to be transmitted to the layers 4a, 4b, and heat insulating property in the electrode direction at the location of the resistor 3 can be enhanced. It is thereby possible to increase the thermal output of the resistor 3, enhance thermal efficiency in printing, maintain a high printing energy density, and to obtain a high high-speed response property.

Title: Semiconductor output circuit
Inventor: KINOSHITA ATSUSHI
IPC: G11C11/41
Filed: 1990-02-14
Abstract: PURPOSE:To adjust a timing with internal read data by adjusting the delay quantity of an equalizing signal activating read data (RD line) to an intermediate level by means of switching a delay circuit composed of an electric fuse. CONSTITUTION:A signal is inputted from an input pad for external signal input 9, and it is amplified in an invertor 8. Then, an N-channel transistor 7 is turned on and a node (e) is set to an L-level. Then, the node (e) holds the L-level by a latch circuit 10 and the node (e) comes to the L-level. Thus, the P-channel transistor of a transfer gate 14 is turned on and the H-channel transistor is also turned on. The equalizing signal (a) passes through a signal line 15 and it is delayed by an invertor for delay 11 when it passes through the signal line 15 and activates an equalizing transistor 4. Consequently, the timing is adjusted to that when an RD buffer circuit 5 outputs an H-level and an RD signal (c) changes from the intermediate level to the H-level at high speed. Thus, the timing of the equalizing signal and that of read data can be adjusted.
