Title: Method of forming electrical interconnection part in silicon semiconductor device
Inventor: RATSUSERU KUREIGU ERUNANGAA
IPC: H01L21/285
Filed: 1988-12-01
Abstract: PURPOSE: To obtain a method where an etching operation of a contact opening part is not critical and a contact between a semiconductor material and a layer of a silicide are maintained as it is by covering a contact island with a supplementary metallic layer obtained through selective growing of a tungsten or a molybdenum before a separation layer is formed. CONSTITUTION: A layer of an ultrahigh heat-resistance metal such as a titanium is depositted on an entire structure, then the titanium layer is reacted on a silicon surface part not covered by a dielectric layer 19 through a proper heat processing to form a titanium silicide to a part of a contact region 18 and finally the remaining part of the unreacted titanium layer is removed through selective etching so as to be self-aligned with the contact region 18 in a contact island 20. Then the tungsten is selectively grown to cover the contact island 20 with a comparatively thin supplementary metallic layer. A titanium nitride layer 202 acts like a core forming base with respect to the growing of the tungsten during this processing and the dielectric layer 19 hinders this growing on the other hand.  Thus, the supplementary metallic layer 30 is placed on the contact island 20 without the need for the any photo-mask operation.

Title: Picture display control device
Inventor: ARISAKA KENJI
IPC: H04N5/445
Filed: 1986-12-18
Abstract: PURPOSE:To attain phase matching by providing a P-channel FET whose gate is connected to the inverted signal of a horizontal synchronizing signal and whose source is connected to a power supply and drain is connected to the input side of a resistor of a Schimitt circuit even when the pulse width of a horizontal synchronizing signal is decreased. CONSTITUTION:An oscillation circuit 1 is oscillated by a charge/discharge con stant depending on an externally mounted resistor RO and a capacitor CO at a range between H threshold level VTHH and L threshold level VTHL being a power potential VDD and ground potential VSS for a Schimitt circuit depending on the ratio of Rf/Rs. When the pulse of horizontal synchronizing signal (h) is generated, the level of a terminal T1 connecting to the inverted signal OSC of an oscillated output signal OSC via the resistor RO reses up to the power potential VDD by the operation of a P-channel FET 22 and the oscillation is stopped. If the pulse is lost, the oscillation is started, but the inverted signal OSC of the signal OSC and the level of the terminal T1 start descending from the potential VDD without fail. Thus, the timing of the oscillation circuit is constant and accurate phase matching is attained.

Title: Actuator for optical head
Inventor: OOTSUKA MIKIYUKI
IPC: G11B7/09
Filed: 1987-11-30
Abstract: PURPOSE:To stably guide a movable part with simple structure by providing a means to guide the movable part in both focusing and tracking directions on a fixed magnetic unit. CONSTITUTION:A guide hole 15 is provided in the center of a main body part of the movable part 9, inserted to a core, and the movable part 9 moves slidably in an axial direction for a yoke 1, and is supported so as to be turned around the axial direction. Based on the fact that a magnetic flux formed in a gap between a core 5 and permanent magnet pieces 6 and 7 pierces through a driving coil 16 for focusing, it is possible to perform driving control on the movable part 9 in the axial direction by controlling the direction and the magnitude of a current to be supplied to the driving coil 16 for focusing. Also, based on the fact that the magnetic flux pierces through only half of driving coils 17a-17d for tracking, it is possible to perform the driving control on the movable part 9 in a circumferential direction. In such a way, it is possible to obtain a guide function with a few amount of resistance without complicating the structure.

Title: Method and device for halftone recording
Inventor: YAMADA KEIKI
IPC: B41J2/36
Filed: 1987-12-02
Abstract: PURPOSE:To prevent the occurrence of a density fluctuation in the same gradation level, by correcting a gradation level signal corresponding to an environment temperature, a resistance value of a heating resistor, and a change in heat accumulation. CONSTITUTION:By referring to the gradation levels respectively in a prior recording pattern of a heating resistor and a present recording pattern of an adjacent heating resistor, significant data '1' is judged only when the gradation level is not less than a predetermined reference value, and significant data '0' is judged when it is less than the reference value. On the basis of the result obtained by referring to the combination of the significant data '1' and '0', an energy to be applied to a target heating resistor of a present recording line is optimized to make a recording density of the same gradation constant. Furthermore, a gradation level signal is obtained with the correction of the factors of difficulty in reproducing a halftone recording with fidelity, such as an environment temperature, a resistance value, and a heat accumulation. In this manner, with the prevention of the occurrence of a recording density fluctuation in the same gradation level, a uniform recording density is made available, and a sufficiently accurate gradation recording can be carried out.

Abstract: PROBLEM TO BE SOLVED: To increase a contact area between a conductive member and a wiring layer to suppress rise in the contact resistance in a contact hole of a small hole diameter by a method wherein the conductive member is buried in a connection hole formed in the wiring layer. SOLUTION: A wiring layer 3 in a floating state is formed on a semiconductor substrate 100.
