Title: Formation of pattern
Inventor: HIRAI YOSHIHIKO
IPC: G03F7/11
Filed: 1985-12-10
Abstract: PURPOSE:To improve contrast by providing a process in which resin and a thin film are exposed through a pattern and the thin film is removed entirely and a process in which he resin is developed to form a pattern. CONSTITUTION:An organic thin film 13 which has a bleaching function with radiation is laminated at every molecule layer on photosensitive resin 12 applied on a semiconductor substrate 11 which includes a step part 10 and its film thickness (d) is uniformed on the resin 12. The thin film 12, therefore, becomes nearly uniform in radiation bleaching function per unit surface area, i.e. contrast improvement effect. Patterning exposure to ultraviolet rays 15, etc., is carried out through a mask 14 after the thin film 13 is formed, and the photosensitive resin 12 is developed after the thin film 13 is removed to form the fine pattern of the photosensitive resin 12. Consequently, the film thickness dependency of transmission characteristics of a light transmission thin film is eliminated to form the fine pattern by the uniform contrast improvement effect.

Title: Semiconductor device
Inventor: KITAMURA MASAYOSHI
IPC: H01L29/861
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To discharge the charges at the boundary between the first and second semiconductor areas of a semiconductor device without giving any influence to the operation of the device by constituting the device so that the third semiconductor area can become a main current route and a prescribed thin film does not become the main current route when a voltage is applied across the first and second semicon ductor areas. SOLUTION: A thin layer 9 which comes into contact with a P-type area 1 and an N-type area 3 and covers the surface of an I-layer area 2 is formed on the side face of a semiconductor device and the impurity concentration in the layer 9 is made higher than that in the I area 2. Accordingly, the resistivity of the layer 9 becomes lower, but the resistance of the layer 9 becomes higher, because the thickness of the layer 9 is thin. Therefore, the I-layer area 2 becomes a current route and the layer 9 does not become any currant route when a pulse-like voltage is applied across electrodes 4 and 5.  When a high voltage is applied across the electrodes 4 and 5, the charges stored at the boundary between the areas 1 and 3 flow to the P-type area 1 or N-type area 3 which is in contact with the layer 9 through the layer 9 at a time constant which is very slow as compared with the width of the impressed pulse and, consequently, the occurrence of element breakage caused by discharge can be prevented.

Filed: 1987-11-02
Abstract: PURPOSE: To increase the number of sounds which can be simultaneously produced by determining an assigned channel at the time of channel overflow based on precedence designation data and channel assignment inhibition flags which are sent from a waveform generation part. CONSTITUTION: A channel control part 6 is provided which compares precedence designation data of respective channels sent from a waveform generation part 4 and generates channel reset data based on channel assignment inhibition flags sent from the waveform generation part 4 and a channel overflow signal sent from a key operation detection part 2. Precedence data of channels whose channel assignment inhibition flags are '0' are compared to mute the channel having least precedence designation data at the time of channel overflow, and a new sound is assigned. Thus, the number of sounds which can be simultaneously produced is increased.

Title: Pilot operation type switching valve
Inventor: YAMAMOTO KOHEI
IPC: F16K17/10
Filed: 1986-11-20
Abstract: PURPOSE:To prevent a liquid spill at the time of shut off by forming a poppet valve section at one end of a valve lug applied with the liquid pressure of the second port in equilibrium and communicating or shutting off the first and second ports with this poppet section. CONSTITUTION:When the first port A1 is connected to a liquid pressure source, a check valve 37 allows the free flow of the pressure liquid from the first port A1 toward the second port A2. If the first port A1 is connected to a tank, the flow of the pressure liquid from the second port A2 toward the first port A1 is shut off by a check valve 37 and a poppet valve section 28 seated on a valve seat 24 by a spring 33, thus the flowout of the pressure liquid from a load system is blocked, and the load system is locked. In this case, the liquid pressure of the second port A2 is applied to a valve 27 in equilibrium, thereby the poppet valve section 26 is seated on the valve seat 24 by the spring 33 regardless of the load.

The character output transistor Qc is turned on by the character signal while the differentiated signal of its emitter output goes to a single peak pulse different in polarity for rising and falling the character signal. When the blanking signal delayed in phase by DELTAtau the character signal is applied to emitters of video output transistors Qr, Qg and Qb, conduction at the leading edge is accelerated while the transistors are forced into a nonconducting state at the trailing edge.
